Development of Inspection System for Appearance Quality of Flat Sheet
Takayuki Ikeda
Engineering Div., JFE Electrical & Control Systems Inc.
JFE Electrical & Control Systems Co., Ltd has developed an appearance inspection
monitoring device with optical image sensors of the flat sheet for the finishing line of a paper
mill. The inspection monitoring device detects defects on the surface of paper, such as sticking
paper particle, paper folded and abnormal aligned. These are considered as one of the mostimportant quality control index for the paper mill. Advanced technology for image processing
has been applied to detect the defect with high accuracy.
Two monitors have been already installed and are in operation in the paper mill company forfolio sheeting line; in addition another four monitoring devices with the same technology arebeing used for plain paper copier.

The Countermeasures for Reduction of the Fuel Consumption in Lime Kiln
Hideto Suzuki
Consulting Department, Taiheiyo Engineering Corporation
Over the past years, Taiheiyo Engineering Corporation (TEC), Tokyo has conductednumerous investigations in cement plants around the world for various clients who have process
and operation problems or who are planning for innovations.
TEC have developed successful techniques to diagnose the existing cement plants and to
overcome the existing process/operational problems and to reduce the fuel consumption andthus assuring stable kiln operation.
In the paper industry in Japan is implementing various measures to reduce the fuelconsumption. Although a certain improvement has been obtained, but not to the extent of large
reduction of fuel consumption is obtained, so far.
Hence based on energy-saving technology adopted in cement plants, TEC has conducted
extensive study in Lime Kiln operation achieved following successful results towards reduction

of the fuel consumption.
1)

Diagnosis of Lime Kiln : TEC have conducted a diagnosis study on existing Lime Kiln

towards the existing process/operational problems and to found optimal countermeasures for
reduction of the fuel consumption.
2)

Replacement of existing Kiln Burner: By replacing the existing Kiln Burner with

Taiheiyo’s TMP Burner (Taiheiyo Multi-purpose Burner), TEC achieved improved burnability
efficiency and reduction in the amount of primary air.
3)

Adjustment of Lime Cooler: For the improvement of heat recovery efficiency of existing

Lime Kiln Cooler, Grate Speed Control and Airflow Control was adopted to Lime Kiln Cooler,
for better cooling efficiency.
4)

Adjustment of Kiln Operation: TEC has reduced the amount of water at the Lime Kiln

Inlet Housing, thus optimizing the O2 concentration control, and the of raw meal filling ratio in
the Lime Kiln.
As a result of adopting above mentioned countermeasures, TEC achieved a 13% to 15%
reduction of the fuel consumption.
Introductory Experience of Inspection System for Appearance Quality of Ream
Masami Uchida
Nichinan Mill, Oji Paper Co., Ltd.
At the process for making the ream by stacking cut paper, quality defects such as folding ,jumping or the unevenness occurs sporadically by mechanical causes. So as not to send
defective products to the next process, it is necessary to constantly monitor states of the ream. It
was subjected to visual inspection by the operator before, in order to achieve automation of thetest, where the end of 2006 and later, was installed an inspection system, it exerted a test stableaccuracy.

Operating Experience of Fuel Conversion to Petroleum Coke on Lime Kiln
Mitsuru Takatsuji
Akita Mill, Nippon Paper Industries Co., Ltd.
After the startup of the coal boiler in 2008, the lime kiln became the equipment using heavy
oil most in our mill. Due to the jump in the heavy oil price of these days, the equipment of
petroleum coke was introduced to reduce heavy oil consumption of a rotary lime kiln. An initialproblem was solved at an early stage after operation, mixing ratio of petroleum coke ismaintained as plan.
This paper reports the process for introduction of facility, and operation experience of fuelconversion to petroleum coke.

Revision of Japan Revitalization Strategy and Cellulose Nanofibers
Masayoshi Watanabe
Ministry of Economy, Trade and Industry
Revitalization Strategy of JAPAN was revised 24th June 2014. To put the Japanese economy
on the path of sustainable growth, continued reforms in line with a constantly evolving Growth
Strategy are essential. The aim of this revision of “Japan Revitalization Strategy” is to review
the progress of already implemented policies and to provide basic guidance for remaining tasks.
And it has been mentioned that Promotion of R&D Cellulose nanofibers in this Revision ofJapan Revitalization Strategy. Taking this opportunity, the Ministry of Agriculture, Forestry and
Fisheries (MAFF), and Ministry of Economy, Trade and Industry (METI) launched theinter-ministerial meeting to promote Cellulose nanofibers material in to the society, andnanocellulose forum composed of industry, academia and government, was also established.

Manufacturing of Cellulose Nanofiber and Sheet-making Technology
Hayato Fushimi
Incubation Section, New Business Innovation Center, Innovation Promotion Division,
Oji Holdings Corporation
Cellulose Nanofiber (CNF) is nano size cellulose fiber with high aspect ratio, which is
produced by fibrillation of pulp. In order to facilitate fibrillation of pulp efficiently, weinvestigated new chemical pretreatments (e.g. Oxidation, Esterification). Using these techniques,
we can control its size (short or long, coarse or fine) and surface charge (anionic, cationic or
neutral).We can also introduce reactive or hydrophobic substituent group on surface of CNF. We
try to apply these unique CNFs to various applications. For example, using high transparency
CNF, we have been successful in manufacturing continuous CNF transparent sheet. The CNF
transparent sheet has high transmittance (>90%), low haze (<1%), high mechanical properties,
tolerability to organic solvent and flexibility. This sheet will be useful as a material for organic

light emitting display, foldable solar cell and flexible TFT substrate. Through making CNF/resin
emulsion sheet, CNF reinforced plastics have been fabricated. The resin emulsion disturbs CNF
aggregation during dry process, and hence CNF is easily dispersed in the resin matrix. Additionof 20% CNF increases bending elastic modulus and bending strength of PE by 2.8 times and 2.2
times, respectively.

Efforts for the Practical Use of Cellulose Nanofibers
Masayuki Kawasaki
Nippon Paper Industries Co., Ltd.
Recently, research and development about the use of celluloses in wood biomass as energy
sources and a wide vareity of new materials have been vigorously carried out. As one of them,much attention about an investigation of cellulose nanofibers and their applictions is being
denoted.
The hydrogen bonds formed between cellulose microfibrils make it more difficult todisintegrate native cellulose into microfibrils with smaller width. Therefore, this technicalproblem has to be perfectly overcome to obtain cellulose nanofibers.
Native celluloses can be converted to individual microfibrils after oxidation mediated by
TEMPO followed by gentle disintegration treatment.
A way of preparing TEMPO-oxidized cellulose single nanofibers, their characteristics andpotential applications are introduced in this report.

Action for the Facilities Accident Reduction in the Pulp Manufacturing Process
Naonobu Motozawa
Kitakami HiTec Paper Corporation
Kitakami HiTec Paper Corp. was established by spinning off the “Kitakami Mill” from
Mitsubishi Paper Mills Ltd. in 2015. From start of operations, our mill has been producing pulp
from domestic hardwoods supplied mainly from Iwate Prefecture and sanitary paper andphotographic base paper.
In recent years, due to the limited capital investment budget, we concentrate our effort to
manufacturing cost reduction, reduction of fixed costs and the work efficiency improvement.
However, we faced to the frequent shut downs of the pulp manufacturing process on our 40

years old pulp plant due to equipment accidents.
Therefore, we, together with Mitsubishi Paper Engineering Co., Ltd. which is responsible forthe designing and maintenance work in the plant facilities, made a factor analysis of equipment
accidents that have occurred in recent years. As a result, more than half of the total accidents
were caused either by the bearing failures or leakages due to corrosion/deterioration of piping.
Through studying the causes of these accidents, various causes including the lack of aged
pipe management, lack of maintenance skill inheritance, skipping or neglectance of
maintenance items and lack of communication between operator and maintenance personnel
were found.
From 2007, in order to eliminate the cause of the accidents, we made a schedule to reducethese accidents to visualize our activity. And then under this schedule, we surveyed themaintenance and monitoring details of each maintenance area and built up “To-Do List” towork with. “To-Do List” mainly consists of four activities.
Through these activities, in 2013, machine shut down of the pulp plant reduced to 4times, 20
hours from that of 16 times, 57 hours in 2006.(Reduction of about 70%)In this paper, activities to reduce equipment accidents are reported along with someillustrative examples.

Operating Experience of Wire Shaking Equipment in Multilayer Linerboard Machine
Naoki Sumi
Kushiro Mill, Oji Materia Co., Ltd.
Recently, in order to compensate for paper strength reduction due to the waste paper ratio
increases, it is very important added in the internal paper strength additive. However, paper
strength improvement effects have become difficult at high addition area. It has to dividend
increase of kraft and internal paper strength additive, which is a factor of rising costs.
This time, we introduced wire shaking equipment at a multilayer linerboard machine for the
first time in the country. We obtained paper strength advancement by formation improvement.
As a result, it was able to achieve the dividend reduction effect of fresh pulp and paper strength
additive.
Formation improvement show a high tendency according to high basis weight, it have gained
a 30% increase at the 280g / m2. The highest frequency and stroke produced great improvement.
Also, advancement of bursting strength shows a high effect at high basis weight. It had
gained 5% up at the 280g / m2. This is the same result as the formation improvement. It waspossible to clearly see the relationship of specific bursting strength advancement and formationimprovement.

The Highest Nip Load Shoepress in Japan-Energy Saving by Introduction of High Nip
Load Shoe Press to the Container Board Machine
Akio Kato
Yashio Mill, Rengo Co., Ltd.
As companies are expected to take environmental actions, Rengo established“Eco Challenge020” as the company's environmental action plan and is strenuously working to reduce thecarbon emissions by 32% in 2020 compared to 1990 levels. In addition, Saitama Prefecture,
where Rengo Yashio mill is located, has set the reduction target of CO2 emission by 13% in2019 compared to the average level between 2002-2004 by enforcing the local regulation of
global warming prevention since 2009. Moreover, energy saving is the urgent issue of Yashio
Mill because of the raising fuel cost in recent years.
Against such a background, Yashio Mill PM1 (medium machine) introduced the high nip loadshoe press with an aim of improving the productivity as well as reducing the steam consumption.
The outline of the retrofit and an operating experience will be discussed in detail below.

DeBottleneck Project of the Duplex Board Machine
Yasuyuki Yazaki
Kobayashi Engineering Works, Ltd.
The UP-GRADE Project for duplex board machine, Kobayashi Engineering Works, Ltd.
received an order from SKIC (Siam Kraft Industry Co., Ltd. in Thailand) in 2012 was started.
Former name of TUPI is a subsidiary company of SCG (Siam Cement Group) who is thebiggest enterprise in Thailand. TUPI changed their name to SKIC in the anniversary of 100
years of the foundation in December 2013.
In 2005, we received an order from former TUPI of relocation project of a machine which
was No.7 machine belonged to Oji Paper Co. Fuji mill in that time and the operation of thisPM9 was started in 2007. This machine is High Speed Ultra Former consists of 7 layers andexclusively producing coated duplex board. The Contract of this project included the installation
work, commissioning work and performance guarantee and we could fully and smoothly madeour performance conforming to SKIC's needs.
According to this good achievement, we received another order of renovation work for
production increase and quality improvement in 2009 and the modification work was made in
November and December 2013 including the machine start with stock. This work wascompleted within shortest period because the machine was stopped during the production
requirement.
In this paper, I make a report about PM9's start-up.

Our Approach to P&S Business / VOITH Group
Takanori Goto
Research & Development Dept., Voith IHI Paper Technology Co., Ltd.
For the past decades, the situation surrounding paper industry has been changing dramatically.
To enhance the production efficiency is one of the most important concerns. Under this situation,
VOITH Paper has set up a new business line of P&S,“Product & Service”. This is a message forour market needs and we'd like to support customers' various kinds of suffering with new value
components other than big investments. That is to say, we'd like customer to support smaller
investment, but make a maximum profit.
In this paper, we will introduce our new concept “P&S” business and latest technologies ofrelated to some stock preparation equipment's components.

Innovative Chemical Approach to Lower Energy Cost by Dehydration Agent in Press
Process
Hidekazu Tada
Research Dept，Nissin Kagaku Kenkyusho Co., Ltd.
In the paper-making process, the press part squeezes out moisture by pressure treatment fromthe wet paper web dried by wire part that is a last process, and assume the role conveyed todryer part that is a next process.
Thermal dry cost in dryer part is higher than mechanical dry cost in press part. Therefore, it
can reduce the paper-making cost that improving dehydration as much as possible in the press
part.
“Newluster A-25” as a felt warm-up agent improve nip dehydration by applying to felt, andit has an effect shortening the period required for initial warm-up of the felt.
Continuous use “Newluster A-25” during operation, the moisture of wet paper web isreduced in the press outlet, and according to the effect, it is expectable reduction of the amountof dryer steam or improvement in paper machine speed.
In this report, we introduce the effect of the press dehydration agent “Newluster A-25” withthe verification results by measurement of a paper machine operation data.

Scale Control Chemical Assuring Better Performance of Pulp Process
Rekha Bharati

Scale deposition is a phenomenon that occurs in all pulp & paper making process. The extent,
type and chemistry of scaling depend on type of wood, water and process conditions. Scaling
causes severe unit operations efficiency loss and profitability problems. Calcium carbonate
deposition is a very frequent problem when forming on heat exchangers and digester screens.
This paper reviews (ⅰ) major causes of calcium carbonate deposition; (ⅱ) mechanism of scale
formation; (ⅲ) the process problems caused and (ⅳ) discusses chemical solution that can be
implemented to overcome the problem of scaling inside the digester.

A case history of

successful digester scale control in an integrated kraft pulping process in Asia Pacific, withcrystal modifier type of product is discussed.

Greaseproof Properties of a Surface Coated with a Polyvinyl Alcohol
Masako Kawagoe, Yosuke Kumaki and Shigeki Takada
Kurashiki Plant, Kuraray Co., Ltd.
EXCEVALTM is a novel copolymerized modification of polyvinyl alcohol (PVOH) by aspecial hydrophobic group enhancing its crystallinity and barrier performance at high humidity
conditions. It has been registered as a Food Contact Substance in FDA and it has various
potentials to be used in food packaging papers. In this paper, properties of coated paper with not
only EXCEVALTM but also combinations of EXCEVALTM and other agents by size press aredescribed. The combination of EXCEVALTM and fatty acid emulsions or fluoro chemicals
gives larger contact values for water and oleic acid and higher oil resistance at folding parts than
EXCEVALTM.

Development of New Paper Surface Strength Agent for Paperboard
Taku Ainoya
Research and Development Department, Paper Chemicals Division, Arakawa Chemical
Industries, Ltd.
Paperboard thickness has recent become thinner from environmental policy and carbon
dioxide emissions reduction point of view. Thinner paperboard may show poor strength
properties, therefore, starch treatment onto paperboard will commonly be employed in fortifying
paper strength. Corrugated cardboard is made of large amount of recycled fiber which can

provide poor strength properties as compared with fresh pulp. Surface treatment with starchsolution can be applied in order to cover poor paper strength; however it is not good enough toachieve desirable paper strength for packaging. It is also a problem that high viscosity starchsolution may not be easy to coat the paper surface homogeneously and poor bonding corrugate
cardboard might be produced.
On the other hand, Polyacrylamide (PAM) based surface paper strength agents are available
to prevent such trouble and widely used in industry; however these are more expensive than
traditional starch. In this report, newly developed two types of PAM based surface paper
strength agents “New Paper Surface Strength Agent A” and “New Paper Surface Strength
Agent B” have been introduced. The feature of “Agent A” is that it can penetrate deep into aZ-direction of paper easily and thus, “Agent A” can show better distribution in inducing
compressive strength with small quantity. “Agent B” is a modified high molecular weightsubstance and even higher molecular weight polymer can penetrate into paperboard very well.
These agents can make corrugate cardboard stronger without any trouble.

Compact and Laboratory-Scale Calendering Unit
―Introduction of “Lab Calender”―
Masaru Futaba
Nomura Shoji Co., Ltd.
Sumet in Germany released its latest model of the Laboratory-scale calendering units. The
compact Laboratory calender is a table-top design. The heated bottom roll is constructed frompolished steel. The exchangeable top roll is constructed from steel, high-glossed polished,coated polyurethane, HNBR or composite as desired. An acrylic glass acts as a safety guard
from injury. An integrated touch screen is used to set parameters and monitor the unit during
calendaring. The sample is pulled through the rolls at a regulated speed and rolls- pressure iscontrolled. The advantage of this machine is flexibility because of the easily changeable rolls
only taking in a few minutes. Short heat up time of the rolls is due to the small diameter, andconstant temperature profile at the rollers is due to the special heating technology. The
integrated sensor in the roller enables the control of the temperature in roll surface in highaccuracy. This calendaring unit provides highly correlated results with the production machineand ensures the saving of time and costs of the testingNew Type, Automatic Small Roll Wrapping Machine
Hiroyuki Kasai
Maruishi Co., Ltd.
With the increased speed and width of paper machines, larger paper rolls are produced foreven faster printing machines. Corresponding to these requests, each machinery manufacturer istrying to develop high-quality, full automatic and labor-saving winders for bigger paper rollswith good quality. Thus, for more stable and efficient production, the recent trend of thefinishing line is one unified wrapping system optional with the diversity of wrapping forms forvarious paper rolls from several winders.
I would like to explain in details the newly developed “Automatic Small Roll Wrapping
Machine” which is suitable for the variety of paper rolls in small lots as well as the limitationof the space required.

Energy Saving and Efficiency of Cleaner Equipment―Cleaning Efficiency, Energy Saving, Pulp Fiber Recovery―
Junichi Yano
Sales. Dept., Kawanoe Zoki CO., LTD.
Cleaner system which can perform higher cleaning efficiency, or can be operated at
equivalent to or higher cleaning efficiency compare to the conventional cleaner at lower energy
consumption, and in the other case cleaner which can recover more pulp fiber is needed.
Cleaner is indispensable equipment in the cleaning process, and must satisfy those requirements.
When higher cleaning efficiency is required, it is often the case that removal of light weightdebris, such as adhesive material, plastic or rubber, are insufficient. To increase speed of vortex,
smaller diameter cleaner design is required. To reduce energy consumption in cleaner system,
such a cleaner type which can perform high cleaning efficiency even in the operation of higher
feed consistency can meet such a demand. To increase fiber recovery from cleaner final reject,cleaner system which can prevent pulp fiber flow into final reject can fulfil the necessity. We
introduce cleaner technology which can meet such a demand of higher quality and energy
saving.

Waste Water Treatment Performance Diagnosis Seen from Activated Sludge
Naoki Akiyama and Yuko Watanabe
NIPPON RENSUI CO.
The waste water treatment performance diagnosis seen from activated sludge which we
provide is comprised of multiple evaluations on the biota by microscope observation that
include the evaluation of protozoa as well as metazoa of the activated sludge, that of biologicalproperty of the sludge floc (aggregate of bacteria), identification of emerging species and theirvolume among filamentous bacteria and actinomycetes, and further include the evaluation of theconditions of our original index organisms in the sludge.
The evaluation of the biota is done by using literature information and pragmatical indicesestablished by the analysis of biotas and waste water treatment data collected from more than
200 waste water treatment facilities.
Therefore, with our diagnosis described above, we can understand the conditions of waste
water treatment, problem and its cause more accurately than the conventional waste water
treatment managing method using protozoa and metazoa as indices.
In this report, we would like to introduce you the examples where we applied the diagnosis
for and successfully solved the problem of the rising of sludge interface and the floating ofscum in the sedimentation tank as well as the issue of rising COD of treated water.

In order to cope with the global greenhouse problems due to increasing carbon dioxide
emission from using fossil fuel more over the 200 years, it is essential to develop technologies
for renewable energy and to utilize biomass more to reduce usage of fossil fuel.
Andritz has been focusing efforts to develop such renewable energy technologies. Today,
more than 50% of Andritz' business is related to sustainable energy and green biomass
utilization.

The History of Technological Developments in Pulp and Paper Industry: From Ts'ai Lun's
Invention to the Birth of Modern Pulp and Paper Industry
Part 2: Unique Modification in Japan that Resulted in Washi Culture
Kiyoaki Iida
Paper making process that was invented in China arrived at Japan in the fourth or fifth
century, and was developed to a unique one there. Mulberry and paper bush, which were main
fiber sources in Japan, gives good sheet strength by relatively slight beating, maintaining theirfiber length. This characteristic of the fibers, the use of viscous liquid from a certain plant, neri,at sheet forming and the modified sheet forming method called Nagashisuki perfected theprocess of washi, Japanese paper, making. The paper was good for writing with brush, and alsostrong enough to be used as a material for various commodities in daily life in Edo Period. In
the beginning of the Meiji era, it was exported abroad due to its thin and even sheet formation.
The industry, however, remained a cottage one. As modern printing system was imported andbecame common, washi lost its share to machine-made paper, and declined.

Optimum Operation Method of Activated Sludge Process Using TS Analyzer
Takao Ogawa
Ogawa Environmental Reseach Institute, Inc.
Activated sludge treatment is widely used as the waste water treatment process. However, its
perfprmance is not enough clarified. IWA（International Water Association）proposes anactivated sludege treatment model of ASM（ASM1、ASM2、ASM2d、ASM3）. ASM models
are based only on the mass balance of O2 using values of CODcr, and they are not applicable tothe actual industrial waste water which has large fluctuation of water quality.
In this paper, a new model ,which is applicable to the treatment process of actual industrial
waste water as well as conventional activated sludge process, is proposed in addition to themeasurement method using TS analyzer. The activity of activated sludge changes with thehabitat condition in uptake, assimilation and dissimilation of organic matter in waste water withthe consumption of dissolved oxygen. This proposed model considers the real activity of sludge
calculated by the oxygen consumption rate measured with TS analyzer.

Creative Design of Practical Robots
Shigeo Hirose
HiBot Corporation
Although the word “robot” was inspired by human workers, we do not need to imitate
human figures when we design a practical robotic system for some specific applications. Instead,
we should be free from all the preconceptions and we should select unconventional shapes inthe design of the robots. In my career as a robot researcher in Tokyo Tech for more than 40
years, and CTO of Tokyo Tech start-up company HiBot corporation, I have been enjoying thedesign of more than 150 robots.
In this talk, I will show some of the examples of creative designs, such as the design ofsnake-like amphibious robots, the snake-like rescue robots, the snake-like multi-joint arm,
which is already in use in the assembly line of automobile industry. The spider-like walking
robots, such as a walking and roller skating hybrid robot, a walking and crawler hybrid robot
will also introduced.
In the final part of the talk, I will summarize the tips to make creative design of robotics
mechanisms and discuss the future direction of the development of robots and ideal relation
between robots and human society.

The Optimal Security Design for a Production Control System
Shoichi Doi
Solution Service Business Headquarters, Yokogawa Electric Corporation
In recent years, sophisticated cyber-attacks that target factories and plants have increased
even in production control systems. Due to such increases in threats and changes in theenvironment, the importance of security measures has become even more urgent. In fact, since2010 damage caused by malware infection has increased significantly.
However, this does not mean that blindly introducing security technology will be sufficient.
Unlike information systems in general, a stable, real-time operation on a 365 day/ 24 hour basis
is essential considering the sophisticated environment of control systems.
YOKOGAWA group support has taken a holistic approach to security measures in which
strategic defense-in-depth concepts are used to effectively evaluate potential risks, consider
technical measures and continuously update the system’s lifecycle. We believe improvements
on a continuous basis are important during operation. Measures are necessary to assess andmitigate the risks identified within the control system and to be better prepared to recover thesystem in the case of an emergency.

In YOKOGAWA group, by investigating and researching conditions in which security
measures are implemented in control systems and the practical use of the latest security
technology, we are currently developing effective solutions and optimal measures for a variety
of system configurations for different industries and applications. Over the lifecycle of thesystem, we are committed to providing the best possible solutions and services to ensure highreliability of systems and to provide customer-specific security measures so that stable operation
can be maintained.

Hemicellulose Recovery from Black Liquor Discharged during Soda–Anthraquinone
Cooking of Bamboo

Kengo Magara, Tomoko Shimokawa, and Tsutomu Ikeda
Forestry and Forest Products Research InstituteWe investigated the soda–anthraquinone cooking process of bamboo chips and the recoveryof hemicellulose precipitated from the resulting black liquor to study how bamboo
hemicellulose may be utilized. The cooking efficiency of bamboo chips improved after hot
water extraction, probably because a part of the starch that consumes the active alkali during thecooking process was removed by the extraction. After cooking, hemicellulose with higher molar
mass value was precipitated from the black liquor. Recovery yield of the precipitate bydecantation was approximately 6.5 g from 300 g of dried bamboo chips, and it was increased byadjusting the pH of the black liquor to 11.5.

Countermeasures for “Hydrangea-like Dirt Spot Defects”of Coated Paperboard
Takako Segawa and Mitsutaka Kondo
Innovation Promotion Division, Oji Holdings Corporation
Coated paperboards are used in packages, for facial tissue and commodities. They havesometimes quality problems caused by waste paper contained in their raw material.
One of the particularly important problems is “Hydrangea-like dirt spot defects”.

It iscaused by the sublimation transfer sheet contained in the paperboard. Sublimation ink of thewaste paper containing in the paperboard migrates from inside to the surface of the paperboard
gradually during a few months, then they will appear as spot defects like Hydrangea.
We investigated a method to detect the sublimation dye in the waste paper quickly. We
focused on the volatility of the sublimation dye.
As a result, we succeeded in developing the detection system with the FAIMS sensor which
can certainly detect the specific volatile components of the sublimation dye in the waste paper
rapidly at room temperature.
In the future, we will try to develop an automated system for removing the sublimationtransfer sheet from the waste paper in the actual production line.

Introduction and Operating Experience of the No.2 Gas Turbine Plant
Yasuo Kobayashi
Niigata Mill, HOKUETSU KISHU PAPER CO., LTD.
We run the mill emphasizing the environment, based on the company’s corporate philosophy.
We have improved CO2 emission intensities with continued activities of saving energy on
power plant sections, introductions of large scale Soda Recovery Boiler and Biomass Boiler
utilizing construction waste material, fuel source of existing boiler and turbine have beenchanged to natural gas. We have also experienced violent fluctuations of energy prices aroundthe failure of Lehman Brothers and felt the necessity of diversification of energy source causedby the Great Japan East Earthquake. Against such a background, we planned to introduce the40MW class Gas Turbine divertible of aircraft engine, as renewing the existing outdated Oil
Boiler, 18MW-class Steam Turbine and 17MW-class Gas Turbine.
No.2 Gas Turbine plant has started business operation since March 2014. In this paper, we
briefly describe the outline of the equipment and operating experience of No.2 Gas Turbine
plant.

Example of Energy Savings in the Press Section of the Paper Machine
Junichi Kanayama
Kasugai Mill, Oji Paper Co., Ltd.
Pulp and paper industry is recently required to reduce energy costs because of sudden fuelcost rise and shutdown of nuclear power plant in Japan.
At Kasugai mill of Oji paper, we are working on energy saving activities with a target to
reduce 2.5% of total mill energy consumption and we have focused on the press section as it isneeds the most power consumption in the paper-making process. We have attempted energy
saving measures by shutting off the felt suction boxes of roll press 1P positions near the start ofthe press section, and 3P shoe press positions and this has mostly never been attempted before
on domestic Japanese paper machines.
This article introduces the measures and problems that occurred during these trials.

Operation Experience of MVR Pre-Eva
Hideaki Suzuki
Sendai Mill, Chuetsu Pulp & Paper Co., Ltd.
In Chuetsu Pulp, Sendai Mill produces HW pulp with continuous digester line and SW pulp
with batch digester line.
The weak black liquor dry solids from the continuous digester to main evaporation plant isaround 20 DS % with Pre-Evaporator (Pre-Eva) using the flash steam from the digester
extraction as heat source.
On the other hand, around 13DS% SW black liquor directly goes to the main evaporator
because of no Pre-Eva in the batch digester line.
Sendai mill has been increased SW pulp production since 2009. Because of the pulp
production increase, the main evaporation plant became overloaded.

Pre-Eva with flash steam from continuous digester has been introduced to Japanese mills. In
food processing industry, electricity (compressor) has been used to evaporate the productbecause such steam would not be so available in the food processing mills.
Sendai mill has recently introduced vapor recompression pre-evaporation plant to the black
liquor from SW batch digester to decrease steam consumption of the main evaporation plant ascost saving.
There are no references in Japanese pulp and paper industry for vapor recompression
evaporator with compressor which has been introduced to the food processing industry.
Chuetsu Pulp decided to introduce Andritz Mechanical Vapor Recompression (MVR)
Evaporator for Sendai Mill because Andritz MVR has many references for black liquor
pre-evaporation plant all over the world.
This paper explains the general description of MVR plant and the operation experience.

Calculation of Greenhouse Gas Emissions Through the Supply Chain
Takeshi Yamashita
Environmental Affairs Section, Environmental Affair & Safety Hygienic Department, Rengo co.,Ltd.
We have calculated a emission of GHG through the supply chain according to basic
guidelines for the GHG

emission calculation through the supply chain (Ministry of theEnvironment / Ministry of Economy, Trade and Industry). The total GHG emissions through ourcompany's supply chain was 1,832,000 t-CO2.The breakdown is as follow, the scope 1 emission
was 663,000 t-CO2, the scope 2 emission was 152,000 t-CO2,and the scope 3 emission was
663,000 t-CO2 .It is revealed that the scope 3 emission was

more than the company's total

scope 1 and 2 emission. Furthermore, emissions of the GHG from a product, the service that wepurchased occupied 35% of the emissions through the supply chain, and it became clear to be amain GHG emission source in the supply chain more.

Propagation of Japanese Black Pine (Pinus thunbergii) Seedlings for Restoration of
Coastal Protection Forest
Naoki Negishi, Nobuaki Urata, Katsuhiko Nakahama and Akiyoshi Kawaoka
Agri-Biotechnology Research Laboratory, Nippon Paper Industries Co., Ltd.

Coastal protection forest functions as tsunami damper, prevention of sand erosion and salt
damage caused by strong sea wind. Japanese black pine (Pinus thunbergii) is considered to be
the best choice for these functions. In recent years, to cope with the risk of pine wilt caused bypine wood nematode (Bursaphelenchus xylophilus) variety of pine that are resistant against
Bursaphelenchus xylophilus have been developed. However, pine tree seedlings are produced
from seeds because pines are difficult to propagate by cuttings. Therefore nematode-resistantproperties cannot always be inherited to progeny. Thereupon, in this research the efficientmethod to propagate pines by cuttings are investigated.
Needle leaves from 2 year old Pinus thunbergii specimen, grown in pots from seed ingreenhouse were used as materials for rooting experiments. Cultivation under the environmentof high CO2 concentration (1000ppm) with glutathione,

reportedly related to plants'

photosynthesis, added to the culture media improved rooting rate to approx. 60%. However, it
was unable to produce seedlings because rooted plants transplanted to pot did not sprout.
Therefore, needle leaves were treated with N6-benzylaminopurine, known as artificial cytokinin
to induce new sprout. Then cutting were conducted with treated leaves. Investigation of rooting
rate and subsequent growth showed that even though rooting rate decreased slightly to 40%,
new sprout grew afterwards and seedlings were obtained. Feasibility study will be implemented
if the technique obtained through this research can be applied to the mass production of Pinus
thunbergii seedlings for coastal protection forest.

Kenji Ota
Soka Mill, Nippon Paper Industries Co., Ltd.
The Soka Mill is located in the Soka-Yashio Industrial Park which had been developed in
Saitama Prefecture for the first time. It is typical urban mill and this site is good place for us so
it belongs to the metropolitan area where they consume paper and discharge wastepaper at themost. We have been moving forward recycle business to use wastepapaer which is contained
99% in its stock. This helps us contribute to protect environment.
However, recently we are faced with recycled fiber quality issues because of the increase ofcontaminants and the development of printing technologies. Therefore, the pulp yield has been
deteriorated.
We have installed “The Combisorter TM CSM” to solve pulp quality and yield loss problems.
Here we report my operating experience.

Therefore, observing the plants 5S level is low, it was considered. As a result, management of
the plant manager was important.
Further, it may lead to experts 5S. 5S activated by expert guidance. However, I will stagnate
after training of experts. So, I was considered the cause of the stagnation. I introduce you that

we have devised a management of 5S fixation.

Report on the Results of the Fiscal 2014 Follow-up Survey on “JPA's Action Plan for
Low-Carbon Society” and Related Information on Measures Against Global Warming in
the Japanese Paper Industry
Kazuo Ikeda
Japan Paper Association
The Japan Paper Association (JPA) established its “Voluntary Action Plan on Environment”
in 1997, in response to Nippon Keidanren's call to the Japanese business community to organize“Keidanren's Voluntary Action Plan on Environment. Since then, JPA has made a follow-up
survey, and published the results every year.
As its Voluntary Action Plan finished in fiscal 2012, JPA started new plan called “JPA's
Action Plan for Low-Carbon Society” and has been actively addressing global warming
prevention, in order to achieve the following targets set in the plan:* Compared to BAU scenario, reduce fossil energy-derived CO2 emissions by 1.39 million
tons in fiscal 2020 from the level of fiscal 2005.
* In view of securing forest resources and increasing forest carbon sink, expand forest
plantation areas owned or managed by the paper industry at home and abroad to 800 thousand
hectares by fiscal 2020.
According to the results of the fiscal 2014 follow-up survey (actual results for fiscal 2013),
fossil-energy derived CO2 emissions in fiscal 2013 was 18.58 million tons, compared to 24.91
million tons in fiscal 2005. Compared to the BAU emissions for fiscal 2013 (21.28 million tons),
actual emissions in fiscal 2013 decreased by 2.7 million tons. This is attributed to eachmanufacturer's active efforts such as energy saving and energy conversion from fossil energy tonon-fossil energy like biomass energy.
In addition to the results of the follow-up survey, this report introduces the current energy
situation in the Japanese paper industry, and outline of the next phase of JPA's Action Plan for
Low-Carbon Society spanning the ten-year period from fiscal 2021 through 2030, and the latest
information on the industry's measures against global warming.

The History of Technological Developments in Pulp and Paper Industry: From Ts'ai Lun's
Invention to the Birth of Modern Pulp and Paper Industry
Part 3: Paper Making in Islamic Lands and Its Transfer to Europe

Kiyoaki Iida
Paper making process invented in China travelled westward. It arrived at the Central Asia in
the fifth century and Iraq in the ninth century. Then, it spread to Syria, to Egypt, through theNorth Africa, and to Spain at the eleventh century. Along the way, it competed with parchmentthat was durable but costly and papyrus that had a long history as a writing media. As culture
there asked that sheet should be written with pen, not with brush, paper was modified to satisfy
that need, and increased share. In the fifteenth century, paper supported the fully-matured
Islamic culture of which center was Iran. Their paper consisted of well beaten linen rag, and wascoated with chalk and starch, to make its surface good for scribing by pen. Then, imported paper
from Europe which was cheap prevailed in the market, and the Islamic paper industry became
extinct.

Novel Analysis Method for Pulp Furnish Using Tube Flow Fractionator (Part 1)
Moe Fukuoka and Shisei Goto
NPi Research Laboratory, Nippon Paper Industries Co., Ltd.
Hiroki Ohtake

Hokkaido Mill, Nippon Paper Industries Co., Ltd.
The effects of various chemical agents on the agglomeration and fixation of filler particles inpulp furnish were investigated using a new apparatus, called fractionator, based on a tube flow
fractionation. The apparatus separated component of pulp slurry gently by the hydraulic size
against for a constant tube flow. The fibers and fines fractions were analyzed with a laser opticalsensor and images from a CCD camera. The result from the addition of a cationic dry strength
resin to deinked pulp (DIP) revealed that the elution curve of depolarization (D) and scattering(S) signals as indices of fiber and filler, respectively, from the sensor were overlapped while theS-signals of DIP without chemicals was delay from the D-signal. The patterns of those elution
curves added various agents such as coagulant and flocculant were different among the agents.
The images of those pulp fractions showed that the filler particles in the DIP without chemicals
were dispersed. By addition of the chemicals, those particles formed agglomerates bythemselves, and flocs with fibers and fines. The morphologies of filler agglomerates wasdifferent as well.
In conclusion, the method using fractionator was useful to examine the effect of the various
chemical agents in paper making process. This method would contribute to select suitablechemicals and optimize wet end systems.

Hydrogen peroxide?bleaching is a principal method in deinked pulp (DIP) manufacturing. In
recent years, it has become more difficult to keep up an operating standard of brightness as theamount of low-quality recycled has been increasing.
On the other side, monochloramine is widely used for the slime control purpose. We foundthat monochloramine can improve hydrogen peroxide bleaching efficiency in the DIP process.
In this article, we will introduce the brightness improvement program using our oxidant
techniques with a successful case. This technique helped the mill to achieve more efficienthydrogen peroxide bleaching and to reduce total cost of mill operation.

demands of this increasingly important packaging grade, present a number of technicalchallenges to the machinery designer. The press section of the machine is one such challenge.
PMT developed a press concept with the Hamburger group in Germany for its rebuild of the
Rieger Trostberg PM2 in 2002. The concept - Inverted Tri-Ex was such a success that the group
installed a second press of the same design in its new PM1 at Hamburger Spremberg mill in
2006. Subsequently, a couple of years later PMT has started up a third press unit at DS Smith on

PM2 Lucca mill in Italy.
This paper sets out to explain the underlying principles and the evolution of the Inverted
Tri-Ex Press, commencing from the basics of the wet pressing process itself.
The fundamentals of water removal, maintaining white-layer purity and surface smoothness andz-direction strength are succinctly covered. A key factor in the design of the press
is the closure of all transfers resulting in no open draws.

The Newest On Machine Equipment for the Efficiency Improvement― Case Studies of Deposit Removal Facilities on Paper Machine ―Chihiro Murayama
Technical Sales Department, AIKAWA IRON WORKS CO.,LTD.
By recycling papers usage percent increasing and its quality lowering, the difficulties of
impurity removal at paper stock preparation stages are underscored year by year. As the result,the fine impurities reached to paper machine side are increasing, they have chances to deposit
everywhere, and bring dirt troubles. Because cleaning up the deposit by hands requires longtime and hard tasks with the paper productivity drastic reduction, its improvement would be oneof the most important subjects for paper making. We introduce our newest profitable doctors
and cleaners for paper machines to improve this big problem. Additionally we will introduce themost suitable suction roll sealing elements for paper machine energy saving which we became
to supply from this year.

Andritz State-of-the-Art Sludge Dewatering Process― In Combination with Pre-Dewatering Gravity Table ―Tamio Fukuzawa , Toshio Okunishi and Yosuke Takeshita
Andritz K.K.
Andritz sludge dewatering systems treat all residues created in recycled paper mills. In
addition to sludge, these include rejects from various process steps like pulping, cleaning or
screening. Every recycled fiber line needs a proper water, sludge and reject treatment system
in order to be able to operate economically and in an environmentally sound manner. The firstand obvious goal is to minimize costs for resources (water, energy) and disposal. In this article,
the combination of Andritz Gravity Table as pre-dewatering and Continuous Pressure Filter

(CPF) or Screw Press (SCS) is introduced mainly.

Fully Split Mechanical Seal for Shaft Wobbling― One Mechanical Seal can Change your Working Environment Completely !
Provides Clean and Maintenance Free Plan ―Takashi Kamizono
Engineering Dept. John Crane Japan, Inc.
Retrofit shaft seal from gland packing to mechanical seal in pulp and paper mills is proceeded
but it is only limited to the major machines such as pumps for cooking and chemical or refiners.
Gland packing is still applied in raw material tanks or horizontal agitators for chest.
This is because the horizontal agitators often occur shaft runout and vibration. These factors
are long deflecting shaft and changing tank liquid level, etc. So, it is thought that mechanicalseals cannot be applied.
However, there is a mechanical seal that can absorb such shaft runout and vibration by using
rubber bellows. Furthermore, fully split design can reduce cost and time of the maintenance.
We would like to introduce the fully split mechanical seal which can be applied accommodate
the shaft runout and vibration for horizontal agitators with actual experiences.

Web Inspection Camera System with Dust Filter for Tissue― Productivity Improvement by Integrated Camera System “TotalVisionTM”―
Yasuhiro Takeyama
MATSUBO Corporation
It is “Challenging time” producers for household paper such as tissue, toilet roll and towel
paper, because of high demands for quality control from consumers. Even in the severe
competition against low cost imported tissue, Japanese tissue producers should take care of not
only its quality but also cost management. However most of all tissue machines have no web
inspection system (WIS) to detect defect such as holes or dirt, which is standard for paper/board
machines. The only solution for web break trouble, such as web break at unreel in converting
machine caused by pinhole from tissue machine, has been as a rule of thumb. Because
conventional line scan camera inspection systems detect flying paper dust as defects. They
cannot classify “true defects” on the tissue web.

“WebInspectorTM“ the web inspection system by Papertech Inc. (Canada), which havedelivered over 730 WIS and web monitoring system to paper/tissue producers, is introduced inthis article. WebInspectorTM has a powerful dust filter to detect “True defect”.
Furthermore, Papertech can also propose solutions for quality control and cost management.
Their TotalVisionTM system which is an integrated system of web monitoring and web
inspection can specify roots of the troubles (defects, web breaks). It terminates “guess work”
by operators and helps them to SEE defects or web breaks in the upstream process to find theroot causes rapidly, and also give them appropriate solutions. Some cases which achieved cost
reductions and productivity improvements are also introduced.

The Proven Effects of the Reel Optimization System (ROS)
Makoto Matsushita
KGK Engineering Corp.
In the paper manufacturing, the reel process is understood as the end and important process ofthe paper machine and easily related to the final product loss. The patented BLH Nobel Reel
Optimization System (ROS) is a hydraulic force and position control system developed tomeasure and control the nip load directly during the full reeling process, to eliminate thewrinkles caused by air bubbles and the cracks during critical shifting phase, and to improve theroll density. Consequently ROS can decrease the paper loss dramatically and contributes to
produce the optimum density rolls, but also can decrease the losses happened in the next
re-winding process caused by the paper slipping in the roll. We would like to introduce theproven effects of the Reel Optimization System (ROS) with Reel Diagnostics System (RDS)
which has been already operated in European and USA paper mills.

For Sound or Noise in Industrial World Part VII*1― It Thinks about the Noise as Part of T.F.O from SKF ―Yasuhiko Yamasaki
RSS RS SKF Japan.
“For sound or noise in industrial world” is the five in this time. This explanation is anoise by the contamination. The contamination accounts for 14% of the whole of the problem
that the damage at the early stage of the bearing doesn't reach the calculation longevity. The

contamination exists from small one to the big one, and from rigid to soft. And, there is the solidand liquid. I present the example of the soft solid one by this contamination, deprave thelongevity of the bearing by it, and tell how the noise is generated.

Newly-Developed Defoamer and Dosing Control
Yuuji Sonoda
Kurita Water Industries Ltd.
A fatty alcohol based emulsion type defoamer has widely been applied for paper making
process, because of its excellent ability to deaerate white water and less negative impact on
sizing. In this article, we introduce newly-developed emulsion type defoamer “KURILESSⓇ800
series” and “S.sensingⓇ FDⅡ” that enables to quantify foam volume automatically, which has
almost the same performance level with a visual measurement.
Notably, “KURILESSⓇ800 series” has a beneficial effect both in high temperature system
and in surfactant-containing system. These characters have already been proven in actualmachine tests. “KURILESSⓇ800 series” could be expected to be applied to paper and pulp
making process water or wastewater where other types of defoamers have currently been used
for, because it is highly effective to defoam the surfactant component system. As a result, we
believe “KURILESSⓇ800 series” expand the coverage of the emulsion defoamer.
“S.sensingⓇ FDⅡ” is an automatic monitoring system of foam volume, instead of visualjudgment by a operator. The dosage of defoamer can be also adjusted automatically by utilizing
the feeding control function of “S.sensingⓇ FDⅡ”, that adjusts defoamer feed according to the
foaming volume information. We can quickly give a reaction to increase or decrease dosing at
the time of the abnormal foaming. Thus, we expect that “S.sensingⓇ FDⅡ”contributes not only
to cut the cost by the prevention of excessive dosing, but also to prevent foam obstacles causedby any fluctuation.

Construction Cost of KP Mill Construction for Bioethanol Production
Tokiya Yaguchi
Biomaterial in Tokyo Co., Ltd.
Makoto Iwasaki
MIP Consultant Office
Youichiro IsonoIOPTEC Consultant OfficeSecond-generation bioethanol has been promoted as a viable form of renewable energy tosustain the global environment. In Japan, the technological development in commercializing
cellulosic bioethanol production by 2020 has been pursued by the industry, government andacademia, focusing on high-yielding herbaceous biomass and fast growing hardwood as thecellulosic feedstock, and the Kraft pulping (KP) process that can pre-treat the large volumes ofbiomass in preparation for bioethanol production. This report details the capital cost associatedwith constructing facilities for KP process with bioethanol production. The major findings were:
1. The construction costs of new KP mills and mills being planned or under construction
around the world since 2000 were proportional to the scaling exponent 1.03 of theirproduction capacities. The results were determined from a sample size of 85, with acontribution ratio of r2=0.82.
2. The approximation formula can be used to calculate the construction cost of the KP(biomass pre-treatment) portion of bioethanol production facility. For example, a facility
with an economically viable production capacity of 200,000 kL/year would need a Kraft
pulp production capacity of 1,500 ADT/day, one of the largest in Japan. The fixed cost for
constructing facilities including the KP process was calculated as US$0.38/L of bioethanol.
3. The location of the KP mill is irrelevant for the approximation formula. The estimatedequipment purchasing cost is proportional to the production capacity to the 0.6-0.7th power,
which is in line with equipment installation costs reported by NREL to be 1.0 to 3.1 times
the purchase cost. Further research and data is needed to confirm these findings.
4. The fixed cost of bioethanol production using Kraft pulp from new KP mills is extremely
high, necessitating the need to consider establishing bioethanol plants that use Kraft pulp
made from fully-depreciated KP mills to decrease this cost.

The Activity of Energy-Saving Produced Results in a Short Term
Ryosuke Kotani
Nakatsu Mill, Oji F-Tex Co., Ltd.
Amid rising interests over renewable energy, Oji group has been positively progressing theutilization of biomass and hydroelectric power generation. Since paper manufacturing is anenergy-intensive industry, the amount of purchasing energy such as LNG is still large. As recent
rise in energy prices influencing severely over the profits of the industry, searching andpracticing energy-saving matters that can be realized in short term are desired. Since setting up
an aim of reducing 1.5% of energy consumption from the previous year and progressing energy‐saving activities in every Oji FTEX mills, Nakatsu mill has limitedly settled a small team andworked on energy-saving during the second half of 2013 in order to produce results in a shortterm. As a result, 19 actions have progressed in six months and succeeded in reducing 122 kL ofenergy per year measured in terms of crude oil.（corresponding to 0.45% reduction compared tothe previous year）
This paper presents the activity of the “Energy-saving team”, two energy-saving acts“

Energy Saving in Mishima Mill Power Plant, Daio Paper Co., Ltd.
Koji Konya
Mishima Mill, Daio Paper Corporation
Daio Paper Mishima Mill is the nation's largest coastal Mill with 500 thousand square meterswhich is located in Shikokuchuo city. It is the Company's core factory, which celebrated its 70th
anniversary last year. From the fact that is located a lot of equipment in extensive grounds, rawmaterials and water, steam, the system, such as power has become very complex. Furthermore,in the 70 year history, it has been repeated expansion and is a factor to be further complicated.
In this paper, I will describe energy saving of steam-power of the entire plant with a focus on
power generation equipment.
With the goal of improving 2% of generation output, I tried by decompressing the steampressure that I sent to the factory. As a result, 2.4% of generation output improved. I usedsurfacecondenser of V/E and a turbine cooling tower coolant to raise temperature of the water.
As a result, I was able to reduce steam consumption last year.
It is difficult to cooperate because a factory scale is big. However, I think that I was able toget big result by cooperating.

Energy Saving in The Steam ＆ Condensate System
Hitoshi Terashima
Motoyama Shinkoh Co., Ltd.
Compared to the original operating conditions for a paper machine, almost all current
operating conditions, such as paper weight and speed, have changed.
Saving energy may be possible by investigating and examining whether or not the drainage
system has kept up with these changes.
By changing the drainage system to match the paper being made, there should be many casesthat can expect improvements in quality and efficiency as well as realizing steam savings.
Here we report on what can be done from now on for the possibility of saving energy
considering the drainage system, within recent significant improvements in drying efficiency
through sealed hoods, air supply and exhaust, heat recovery system, etc.

Invention to the Birth of Modern Pulp and Paper Industry
Part 4: Paper Making in Europe and Its Adaptation to Printing NeedKiyoaki Iida
Paper making process which landed in Spain spread in Europe. Linen rag was well pounded,from which wet sheet was formed on a mold. Sheets were stacked with a layer of felt between
them, and pressed for dewatering. Then, they were dried in a room, being hung on a rope. They
were further impregnated with gelatin and polished with stone. The process was improved incost with refined use of water wheel, flow operation in a mill and standardized product size,
which were prerequisites for the coming industrial revolution.
Paper was sized in each land with its own method. In Europe, paper was impregnated withgelatin as an after-treatment. Its surface had to be strong against scribing by pen to be a
substitute to parchment. As printing became common in the fifteenth century, less sizing was
required. Then, paper machine was invented and became prevalent in the nineteenth century.
Internal sizing was invented and rosin sizing was developed. Further technical developments
like tub sizing and modifications in printing press made gelatin sizing dispensable.

Pyrolysis of Wood Meals with Different Lignin Content Altered by Delignification or
De-Carbohydrate Treatment
Kaoru Nishikiori, Kyoko Katsumata, Takuya Akiyama, Tomoya Yokoyama and Yuji
Matsumoto
The University of Tokyo
In order to examine the effect of lignin and carbohydrates on the pyrolysis products of wood,
wood meals (Douglas fir) with different lignin and carbohydrate contents were prepared. By

sodium chlorite delignification of Douglas fir wood meal (lignin content 26.5%), wood meals
with lignin content 1.8 to 21.3% were prepared. By periodate oxidation of carbohydrates, woodmeals with lignin content 45.1 to 67.6% were prepared. These wood meals were subjected topyrolysis by the use of tube type kiln. With the decrease of lignin content from 67.6 to 1.8%, theyield of pyrolysis residue (char) decreased from 48.6 to 27.7%. Interestingly, not only
lignin-basis yield but also sample-basis yield of eugenol, guaiacol and vanillin increased withthe decrease of lignin content when wood meals delignified with sodium chlorite were subjected
to pyrolysis. These products were most presumably derived from lignin. Contrarily,
sample-basis

yield

of

4-methylguaiacol,

4-ethylguaiacol

andisoeugenol

decreasedcorresponding to the decrease of the lignin content of the sample. These results indicate thatyields of lignin-derived pyrolysis products do not always depend on lignin content. Similarly,
there was not clear relationship between carbohydrates-derived pyrolysis products andcarbohydrate content.

Introduction and Operating Experience of the No.2 Gas Turbine Plant
Yosuke Nonaka
Niigata Mill, Hokuetsu Kishu Paper Co., Ltd.
We run the mill emphasizing the environment, based on the company's corporate philosophy.
We have improved CO2 emission intensities with continued activities of saving energy on
power plant sections, introductions of large scale Soda Recovery Boiler and Biomass Boiler
utilizing fuel wood, fuel source of existing boiler and turbine have been changed to natural gas.
We have also experienced violent fluctuations of energy prices around the failure of Lehman
Brothers and felt the necessity of diversification of energy source caused by the Great Japan
East Earthquake. Against such a background, we planned to introduce the 40 MW class Gas
Turbine divertible of aircraft engine, as renewing the existing outdated Oil Boiler, 18 MW-class
Steam Turbine and 17 MW-class Gas Turbine.
No.2 Gas Turbine plant has started business operation since March 2014. Thereafter, Fuelintensities converted into crude oil equivalent and CO2 emission intensities have been
improving. In this paper, we briefly describe the outline of the equipment and operating
experience of No.2 Gas Turbine plant.

The Waste Heat Utilization by an Absorption Heat Transformer
Tomoyoshi Irie
EBARA REFRIGERATION EQUIPMENT & SYSTEMS CO., LTD.
The low temperature heat sources such as hot water less than 100 deg C are usually difficult
to be utilized because the temperature is too low. An absorption heat transformer was developed
to generate 180 deg C steam by utilizing these low temperature heat sources. A single lift
absorption heat transformer generates 120 deg C steam in theoretical COP 0.5. A double lift anda triple lift absorption heat transformer generate 180 deg C steam in theoretical COP 0.33 and0.25, respectively.

The Highest Nip Load Shoe Press in Japan - Energy Saving by Introduction of High Nip
Load Shoe Press to the Container Board Machine
Ryuji Shinoda
Yashio Mill, Rengo Co., Ltd.
As companies are expected to take environmental actions, Rengo established“Eco Challenge020” as the company's environmental action plan and is strenuously working to reduce thecarbon emissions by 32% in 2020 compared to 1990 levels. In addition, Saitama Prefecture,
where Rengo Yashio mill is located, has set the reduction target of CO2 emission by 13% in2019 compared to the average level between 2002-2004 by enforcing the local regulation of
global warming prevention since 2009. Moreover, energy saving is the urgent issue of Yashio
Mill because of the raising fuel cost in recent years.
Against such a background, Yashio Mill PM1 (medium machine) introduced the high nip loadshoe press with an aim of improving the productivity as well as reducing the steam consumption.
The outline of the retrofit and an operating experience will be discussed in detail below.

Suggestions towards Energy-Saving for Refining at Stock Preparation
Masaharu Menjo and Akifumi Hatta
Valmet K. K.
In this paper, two topics are to be described how to reduce energy consumption at stock
preparation. In general, refining process requires lots of electricity. Therefore, it can be
mentioned that there are still some big possibilities left for energy-savings.
One of these two topics is newly developed conical type refiner (OptiFiner Pro).With its
unique refining mechanism, the refining efficiency is highly improved by comparison withprevious generation of conical refiners (for example, OptiFiner RF). Due to the high refining
efficiency, we have experienced some installation cases indicating that previous generation of
two or three conical refiners can be replaced by only one OptiFiner Pro. In addition, there is also
one installation case that successfully ended by the replacement from conventional type of threedouble disc refiners with only one OptiFiner Pro. Our customers are satisfied with not only
energy savings but also reduction of maintenance cost for stopped refiners. By choosing suitablefillings (i.e. refiner segments), OptiFiner Pro is available for virgin pulp refining (i.e. hardwood
and softwood) as well as recycled pulp nowadays.

The other topic is refiner segments with much narrower bars and grooves than ones fromconventional refiner segments. We have finally succeeded to manufacture these refiner
segments (MicroBar) by casting and MicroBar is now widely used for hardwood refining at
stock preparation as a good tool for energy- savings. The refining intensity of MicroBar is sohigh that the motor load for double disc refiners can be lowered by using MicroBar.
There is also possibility that one double disc refiner can be stopped from where there are two
double disc refiners installed in series. For softwood refining, we have found a very effective
pattern throughout test runs with a customer in 2014. This new pattern for softwood refining is
also to be briefly described in this paper.

It is accepted that, in the pulping process, we are able to achieve a reduction in power
consumption by installing an energy-saving rotor at the screen and additionally by reducing therotating speed of the rotor.
On this basis, we installed the same kind of rotor to the headbox screen in the paper making
process in order to assess any possible energy savings. We have now carried out actual machine
tests using the energy-saving rotor manufactured by Aikawa Iron Works Co., Ltd.
In this paper, I will explain our operating experience of the energy saving as a result of
installing the energy-saving rotor for inward type headbox screens in the case of N‐2 M/C．

Naoyuki Sekine
MPM OPERATION Co., Ltd.
Our No.4 paper machine operated at Hachinohe mill of Mitsubishi Paper Mills LTD was notreally outstanding at steam saving as compared with other paper machines.
A factor is difference of the steam consumption at the dryer part. And problems are lower
efficiency of the steam equipment and differences of the operational condition, the mechanicaldrainage flow, and the drainage balance. We modified the drainage system as a solution of theseproblems in December 2013 and achieved big steam saving.
This report is described about the past problems, the modifying of drainage system, and theresult of steam saving.

Bulky Paper from Chemically Crosslinked Hardwood Kraft Pulp Fibers
Antti Korpela and Atsushi Tanaka
VTT – Technical Research Centre of Finland Ltd
There is a general interest among paper and board makers to produce lighter and bulkier
paper and board products.

The aim of the present study was to characterize chemicallycrosslinked hardwood kraft fibers regarding their potential in making bulky paper and board.
Crosslinking agents are molecules that contain two or more reactive ends that form inter-chain
covalent bonds with cellulosic hydroxyl groups. The formed water resistant crosslinks prevent
mutual movement and relocation of cellulosic chains and further, changes in fibers physicalshape and dimensions, as the fibers are wetted, mechanically stressed and dried. In paper andboard making chemically crosslinked fibers are less prone to swelling and deformation.
Blocking of fibers surface hydroxyl groups by reactions with crosslinking agents reduce fibres
ability to form inter-fibre hydrogen bonds.

In the present study the crosslinking treatments

were carried out in laboratory scale. The used pulp was never-dried, bleached hardwood (Betulapendula) kraft pulp. Experiments were performed using various dosages of crosslinking agents
followed by beating of the pulp and subsequent standard laboratory paper sheet making. The
crosslinking treatments resulted in significantly increased paper sheet bulk. As expected,
crosslinking decreased the dry strength of the sheets. However, after moderate refining,crosslinked pulps had much better tensile strength at constant bulk than never-dried or driedreference pulps. An additional advantage of crosslinking treatment is that it improves
dewatering ability of the pulp significantly. Thus, use of chemically crosslinked pulp offers an
attractive option for manufacture of bulky printing papers and paper boards.

Current Situation of the World’s Forests and Issues of Industrial Plantations
Hiroyuki Obuchi
Japan Overseas Plantation Promotion Center
Based on "Global Forest Resources Assessment 2010” that FAO performed in 2010, thecurrent situation of the world’s forests was introduced. The decrease in world’s forests area
diminished, but approximately 13 million hectares with annual average is still decreasing in the
2000s. In consideration of increase by afforestation, approximately 5 million hectares withannual average is net reduction in the 2000s.
Concerning increase in the population of the world and the demand for wood increase in the
future, there are two important issues for industrial plantations. The first is to raise theproductivity of planting area, and it is necessary to continue improving the forest tree breeding
and the silviculture technology. The second is the selection of good trees which grows up with
the inferior land and the development of new markets.

Trend of KP Continuous Digesters and the Related Basic Theory
Makoto Iwasaki
MIP Consultant OfficeDuring 70’s some injured fishes and marine animals were found in the Baltic Sea. The reasonof phenomena seemed to be an effluent from pulp mill. KTH (University) and STFI (ResearchInstitute) in Sweden started to research for decreasing kappa No. entering into bleaching stage
in order to reduce chlorine dosage. It is difficult to archive both reduction of kappa No andmaintain pulp yield at the same time, so they and machinery companies changed a conventional
pulping process and developed some new cooking processes such as MCC, ITC, Lo-solids
Compact Cooking. In this paper the trend of KP continuous digester and the rerated basic
concept and theory behind of development on new processes are described.

Producing Polysulfide by Electrolysis of White Liquor, Development and Integration withKraft Pulping Process
Kazuhiro Kurosu
Research Laboratory, Nippon Paper Industries Co., Ltd.
An electrolytic oxidation process to produce polysulfide (PS) from the kraft white liquor(WL) and integration of this process to the kraft pulping (KP) system is described. Electrolyticoxidation of WL through electrolytic cell provides highly concentrated PS liquor in the anodecompartment with extremely high efficiency, and simultaneously, sodium hydroxide andhydrogen gas are available in the cathode compartment.
We have succeeded in the log-term stable operation of the electrolytic cell in practical scale
for the first time in the world. And more, the merit derived from the integration of thistechnology with KP process have been actually verified in Nippon Paper Industries, Yatsushiromill, such as follows.
1. Significantly high yield gain of pulp was available by combination of this electrolytic
process and modified cooking process, and agreed with previous lab data.
2. The cathode liquor served as an excellent alkali source for oxygen delignificationcompared with existing oxidized WL.

Cooking Additives for Kraft Pulping― The Reasons Why SAQⓇ Has Been Used for Years ―Junji Tanaka
Kawasaki Kasei Chemicals Ltd.
It is very important subject for pulp mills to increase pulp yield from a viewpoint of not only
the improvement of profitability but also the effective use of fossil fuel and forest resources. In
order to improve pulp yield, cooking additives have been applied. Polysulfide, anthraquinone
compounds (SAQ or AQ) and surfactant are currently-used, in particular, SAQ has been usedsince 1976 in Japanese pulp mills. Because SAQ has some features; (i) superior impregnation
into wood chips, (ii) many derivative effect for pulping process, and (iii) applicable to all woodspecies. Furthermore, we would like to add our continuous efforts to confirm effects on theactual operation.

Inorganic Scaling in Pulping Operations & Ways to Live with It
Rekha Bharati
Business Development & Application Manager, Pulp, Asia Pacific, Solenis
Inorganic scale deposition is a phenomenon that occurs in almost all pulp and paper making
processes. The root cause of this scaling is the presence of trace metal ions and the very suitableprocess conditions for crystallization to initiate. In bleach plant scale formation is mainly due totrace metals or non-process elements (NPEs), while in evaporator, fouling also takes place due
to process chemicals, the sodium salts. Strict waste water discharge using counter current filtrate
management in bleaching and higher black liquor solids in evaporators and concentrators makes
scaling even more problematic.
It is an unwanted occurrence that causes a number of operational problems, downtime andincreased production cost.
This is a review paper dealing with (i) major scale deposition problems (ii) reasons for
scaling and (iii) solutions that can be implemented to minimize the issue or live with it. The
paper is focused around scaling in bleach plant and evaporator area.

The Review of Operating Experiences of Biorefinery Work
Suguru Nakamura
Yonago Mill, Oji Paper Co., Ltd.
As a part of biorefinery business of OJI group, we started commercial production of
hardwood dissolving kraft pulp at Yonago mill since May 2014. At the same time, we also
initiated verification tests for furfural production. In this report, the review of our biorefinery
process and operating experiences are presented.

Biorefinery of Woody Biomass
Hidetaka Taneda
Nippon Paper Industries Co., Ltd.
A chemical article derived from biomass attracts attention for reasons of the reduction ofcarbon dioxide and substitute of oil resources. Large-scale research and development have beenstarted in Europe and America, but the process only to use edible biomass is in operation, andthen utilization of food resources for another purpose becomes the problem. Woody biomass,
which is the non-edible, has a great advantage because the infrastructure exists to handle,
circulate, and use it. However it is not easy to refine woody biomass because of the hard
structural nature. Therefore further research and development is necessary to overcome thedifficult nature of lignin then will make competitive products from lignin. The pulp and paperindustry has operated biorefinery process to produce cellulose as pulp, and utilize lignin as fuel.
For the future, new technology will be developed to convert three components, cellulose,
hemicellulose and lignin, into chemical materials with these natures. It could provide theindustry with the chance to utilize it’s forest resources and existed technologies.

DIP Technologies for Lower Grade Raw Material― Keep Product Quality and Maximize System Efficiency & Yield ―Nobuhiko Okumura
Technical Department, Aikawa Iron Works Co., Ltd.
The trend on using more recycled paper in the domestic market has been desired for the finepaper category. It has been more and more difficult to obtain the high grade recycled paper due
to a smaller distribution of the recycled paper caused by the decreasing paper consumptions, aswell as the decreasing number of exporting the recycled paper to China.
With this background, there are more needs on using the low grade recycled paper based on
the increase of using the recycled paper in the fine paper category, but the inductry is facingsome issues on the low yield rate by the prohibited materials, maintaining the product quality,
and increasing the energy cost due to operating more facilities.
In this section we would like to introduce the technologies using the low grade recycled paper,
which are [facilities for improving quality], [facilities for contributing to the system efficiency],
and [facilities for contributing to the functional improve of the existing equipment], while
giving you some examples based on our experiences.

China Opts for Modern Mechanical Pulping Andritz P-RC APMP
― What Can Europe & Japan Learn from This ? ―Tamio Fukuzawa
Andritz K.K.

Peter Brauer, Johann Grosalber and Heinrich Munster
Andritz AG
Over the past 5-6 years, China has doubled its paper production to almost 100 million t/a andis now the world's leading producer. In the same period, however, production of mechanicalpulp has more than trebled, in spite of a chronic shortage of wood and energy prices at world
market level. The main grades are chemi-mechanical high-yield pulps for printing and writing
papers, board, and tissue, produced primarily using the P-RC APMP process with excellent
energy efficiency. Here we present a range of state-of-the-art equipment and comprehensive
consumption and operating data, including information on the latest waste water technology,
such as integrated evaporation or anaerobic treatment.

Estimation of Merit by Installation of a Press in D0 Bleaching Stage
Yan JuPulp & Energy Projects, Valmet K.K.
Replacing an existing D0 washer such as diffuser or drum washer by a wash press in anexisting D0-EOP-D1 bleaching plant, it is possible to operate a high dilution factor (D.F.) for D0
wash press even if D.F. for D1 washer is operated at a low number, and a large amount of theremaining D1 filtrate can be used as the dilution liquor before D0 reactor. In case study 2, bysending the remaining D1 filtrate to D0 filtrate tank as the traditional way, it can expect to reduce
COD into D0 reactor about 3.1 kg/ADt by which it estimates to reduce the consumption ofchlorine dioxide approximately 0.5 a. Cl kg/ADt. In case study 3, by using the remaining D1
filtrate for both the dilution liquor before D0 reactor and the dilution liquor before D0 washer, it
can expect to reduce COD into D0 reactor about 7.3 kg/ADt by which it estimates to reduce theconsumption of chlorine dioxide approximately 1.8 a. Cl kg/ADt.

The History of Technological Developments in Pulp and Paper Industry: From Ts'ai Lun's
Invention to the Birth of Modern Pulp and Paper Industry
Part 5: Paper, Economy and Culture in the History of Human Society
Kiyoaki Iida
The fact that paper has been used for two thousand years means that people have appreciatedits value for so long time. At the same time, paper itself has been technologically developed tosatisfy needs which followed the economic and cultural progress of society.
Historically, the amount of paper consumed has a positive relationship with the affluence ofsociety that is represented by GDP as one of parameters. When society was stable andprosperous, new technology was invented to meet increasing demand of paper. The paper wasinvented by Ts'ai Lun in the age of Eastern Han when the dynasty was prospering. The bamboo
pulp was developed in the age of Tang and Northern Sung when the culture was at its best in the
Chinese history. Italians impregnated paper with gelatin for book bonding when its society wasflourishing at the Renaissance. Dutch invented Hollander beater and revolutionized beating
operation in the 17th century when they were richest in Europe. England which was leading theindustrial revolution invented paper machine in the 19th century.
These technological developments reduced price of paper which in turn stimulated printing
technology, and printed matters became common in daily life. In Japan, Japanese paper (Washi)
and wood block printing combined made it possible to publish various printed matters in Edo
period. Paper was used as one of basic materials in everyday life as well.
Paper was also a useful tool for ruling in empires covering large territories like Chinese
dynasties and the Mongolian Empire. Europe, on the other hand, developed typography. With
paper produced with efficient productivity and letterpress printing which allowed low cost
operation, printed matters became far more common and popular in Europe than anywhere else.
This availability induced successive social revolutions like the Renaissance, the Reformation,
the Enlightenment age, and the Industrial Revolution.
As Kremer wrote 100 years ago, blossom of mental activity made possible by paper started a
new era of civilization.

Motoyuki Suzuki
Marukin paper company Co., Ltd.
Displaying carbon footprint (CFP) of manufactured articles for daily use is very important to“visualize” the environmental burden, especially life cycle CO2 emission, from daily life. The
goal of this study is to evoke people’s awareness to the environmental burden in daily life
through the calculation of CFP from the sanitary paper, in particular sanitary paper, produced in
Fuji city, Shizuoka prefecture.
Functional unit is applied to the CFP per 1 package consist of 6 sanitary papers with LDPE
package. The life cycle stages in this study are classified into 5 stages, and CFP is calculated as
the total amount of GHG emission from each processes.
The calculation result of CFP of 1 package of sanitary papers was 2,406.90 g-CO2/package
references to unacceptable product category rule (PCR) of “paper and paper board（PCR-025）”.
The component ratio of each life cycle stages are: raw materials procurement stage 5.8%,
production stage 75.8%, distribution and selling stage 13.7%, operation and maintenance stage
0%, disposal and recycling stage 4.7%. The most CO2 is emitted from energy usage of the
production stage, which accounts for 72.1% of the total CO2 emission. Therefore, it is very
important to choose the energy sources with the least environmental burden, e.c. renewableenergy.
All sanitary paper mills discharged great deal of paper sludge (PS) from daily process. The
CFP of sanitary paper is varies from the calculation conditions based on waste water treatment
methods and PS treatment methods. Therefore, it is necessary to review the PCR for clarify therules of wet end process, especially waste water and PS treating methods.

History and State-of-the-Art Technology of Paper Machine Wet Section
Yukinori Takano
Paper Machine Eng. Dept., VOITH IHI Paper Technology Co., Ltd.
Many modern paper making machines for are based on the principle of the Fourdrinier
Machine, which uses a specially woven plastic fabric mesh conveyor belt in the forming section.
This Fourdrinier was invented by Louis Robert in 1799. This Fourdrinier Machine was one of
the earliest of the industrial revolution era continuous manufacturing process. Previously paper
had been made by hand, in individual sheets. The method of continuous production
demonstrated by the paper machine influenced the development of continuous rolling iron andlater steel and other continuous production process.
This paper describes the history, systematic classification, and state-of-the-art technology ofPaper Machine Wet section, especially for graphic paper. There were some great innovations in
the end of 20th century, such as ModuleJet dilution control system in headbox, NipcoFlex Shoepress technology in press section, for example. These made Paper Machines quite wider andfaster, with higher paper quality. But, on the other hand, technology made by those who havegone before us in 200 years ago, were still useful in today’s paper making. This is quite
interesting and we should still learn from our forerunners.

Development of Cover Materials for Press Roll and Shoe Press Belts
Hiroya Shimazaki and Takahisa Hikida
Products For Paper Industry & Laminate Div., YAMAUCHI CORP.
The press section of paper making machines are composed of roll presses and shoe presses.
We developed PU press roll cover quality“High-Top Roll”in 1963, first in the world, andhave licensed this technologies to one of the biggest roll cover manufactures in overseas. Since
then and up to now, we have been developing various types of cover qualities and have been
keeping the top share in the markets by supplying those products to the customers mostly inJapan and Asia. With regard to the shoe press belt, we developed shoe press belt “YNB”in1983, and now have grown up to have almost half of market share in Japan and have been
increasing market share rapidly in Europe, Americas, Asia and other area all over the world.
The suction roll covers are required to have optimum surface design to improve its
de-watering capability and stable bonding strength for longer life-time. Here, we would like tointroduce the latest cover surface design and the new under layer to solve the above issues.
Furthermore, we would like to introduce “High-Top” L-Series which has adapted totally new
concept of bonding system.
For the shoe press belt, utilizing the polyurethane quality and processing technologies
cultivated by “High-Top” roll cover, Super 95 series which we developed in 2009 has been
well accepted by customers and has contributed to extend the belt life even under higher speed
and linear pressure.
Here, we would like to introduce Super 93H series which is upgraded even from Super 95
series.
Operation Experience of the Amagasaki Mill Success Former Introduction
Hiroshi Okuda
Amagasaki Mill, Rengo Co., Ltd.
No.6 Paper machine (PM#6) in Amagasaki mill is producing liner board from 120 to 210 gsm
with 2 layers. It was installed in 1969 as a corrugating medium machine and modified liner
board machine, On Top Former, in 1979. In recent years, PM#6 has faced operation difficulty
due to aging equipment such as adjustment of HB slice lip and it leaded to productivity andquality issue.
In order to solve those problems, PM#6 was modified new former, Success Former, and start

History and the Latest Trend of Forming Fabric
Akira Tajima and Hideyuki Yanai
Technical Development Dept. Nippon Filcon Co., Ltd.
Forming fabrics are used at the wet end of paper machines. The fabric has three distinct
functions; ①to allow water of the pulp slurry to pass through its structure ②to promote theformation of uniform fiber mat ③to act as a conveyor belt transporting the sheet to the next
phase(press section). Formation of the sheet is the most critical phase of paper making.
Therefore, performance of the forming fabric has high importance. Recently, requirements forpaper quality and productivity have increased in the papermaking industry. Such requirements
have resulted in the larger and higher-speed paper machines. Responding to these recent paperindustry demands, forming fabrics have evolved as well.
The first generation triple-layer fabrics had the hope of being an ideal design, yet they did not
expand into the market rapidly. A flaw of these first generation triple layers was that theirstructural design properties allowed for easy internal wear. Second and the third generation
triple-layer fabrics exhibited improvements, and have become a current mainstream design usedon paper machines. Nippon Filcon has focused on developing its third generation, triple-layer
fabrics called the SAKURA and FUJI series. These series, incorporating a unique design called
WSB, have possibly the best resistance to internal wear on the market. Customers haveobserved stable operation while minimizing internal wear. Other value-added designs will be
noted.
In this manuscript, we explain the history of forming fabric weave structures, from single
layer to 3.5 layer fabrics, and their evolution alongside the advancement of paper machines.
Finally, we shall give an overview of the FUJI series, our latest triple-layer design.

New Opportunity with Grade Conversion－ Achievement of Grade Conversion in Accordance with Market Demand －Hidefumi Inoshita
Valmet K.K.
It is a well-known fact that the paper industry and paper markets are changing rapidly as thedigital world changes everything around us. Papermakers are requested to produce proper paper
grade to meet market demand.
New machine installation for quality improvement of some grades require time and costs.
Grade conversion is recognized as the common way to solve, by modification of existing paper
machine with new key components.
For grade conversion, papermakers need to study suitable type of papermaking line,
necessary capacity to meet the market demand, improved properties, possibility to produce
additional grade with existing machine and/or necessity to produce completely new grade.
Grade conversion has some cases like Paper to Board, Paper to Special, Paper to Paper.
Especially the conversion in package grade is on rise.
Global market trend requires economical production of boards with higher efficiency andgood qualities, resulting in lower basis weight grades, usage of economical raw materials,
higher content of recycled furnish, higher machine speed operation and still the samerequirement on board strength properties.
Valmet has developed advanced technologies for multi-Fourdrinier, hybrid and gap formers to
manufacture various types of board grades.
The author introduces some of representative technologies in Valmet's advanced wet parts ofboard machines.

Problems and Measures to Offensive Odor of Wastewater Treatment Facilities and Paper
Making Processes
Hidenori Kojima
Kurita Water Industries Ltd.
In a papermill, a bad odor occurs in a wastewater treatment system and a papermaking
process. Although the odor control chemicals are used for the measure against a bad odor, amore effective application is demanded. Moreover, some odor substances which occur in apapermill have serious influence for the trouble free operation and productivity of a factory.
From such a viewpoint, optimize of the measure against a bad odor and the measure from which
merits are obtained for a factory which is not a mere prevention of bad odor are introduced.
At a papermaking process, hydrogen sulfide generated in paper material slurry and diffuses at
a storage tank or a machine, as this measure, application of odor control chemical which do nothave bad influence in paper making process is effective, and this injection volume can optimize
by ORP. Moreover, microbe control of paper material slurry by an inorganic biocide can prevent
generating of bad odor, and it can improve the productivity of a factory, such as theamount-used cutbacks of papermaking agents. On the other hand, at a wastewater-treatment
process, application of anaerobic inhibitor can remove the hydrogen sulfide in an activatedsludge, and, it contributes to improvement of wastewater-treatment capability. Furthermore, thepurifying equipment which improves corrosive environment can remove low concentrationhydrogen sulfide which exists in a control room, and trouble of control units is prevented.

Novel Analysis Method for Pulp Furnish Using Tube Flow Fractionator (Part 2)
Moe Fukuoka, Hiroyoshi Suzuki, Toru Nakatani and Shisei Goto
NPi Research Laboratory, Nippon Paper Industries Co., Ltd.
The agglomeration and/or fixation behavior of hydrophobic colloidal substances (HCS) in
deinked pulp (DIP) furnish was investigated by using a method combined with confocal laser
scanning microscopy (CLSM) and a tube flow fractionator (TFF) in order to clarify the
influence of wet-end chemicals. A solvatochromic fluoresce dye (SFD) was employed as ahydrophobic probe to visualize the HCS. The effect of wet-end chemicals addition into DIP
furnish was evaluated. The furnish was classified into several fractions, as long fibers, shortfibers, fines and colloidal materials by using the TFF, and the fluorescence of SFD attached onto
HCS in each fraction was observed by CLSM. In the case of DIP without chemicals, thefluorescence was hardly observed in the fractions of long and short fibers, and a lot of
fluorescence patches were confirmed in the fraction of colloidal materials. On the other hand,
after the coagulant addition to DIP, the patches of fluorescence were observed on the surface offibers and the amount of patches in colloidal fraction decreased significantly. It was thought thatthe addition of coagulant induced the attachment of HCS onto fiber surfaces without excess
agglomeration of them. Consequently, this method combined with CLSM and TFF, visualized
the distribution and behavior of HCS in pulp furnish. It can contribute to get more efficient andeffective approach to select proper wet-end chemicals.

The Development of Cellulose Fiber Based Nonwoven Type Separator
Hiroo Kaji, Henji Hyodo, Makoto Kato, Toshihiro Shigematsu and Noriko Kasai
Tsukuba R&D Laboratory, Mitsubishi Paper Mills Limited
Lithium-ion batteries have been regarded as promising high energy storage devices for manyelectronic devices. At the same time, more improvement of Lithium-ion batteries is desired insafety and battery performance. We developed the nonwoven separator for lithium-ion batteries
made from the mixture of cellulose fiber and PET fiber in order to satisfy the safety and highbattery performance.
In the first study, we investigated how the fiber material of nonwoven separator affected onlithium-ion battery performance. There was a good relationship between the porosity of theseparator and the battery performance. The nonwoven with a high porosity was a preferable
separator for lithium-ion batteries. Cellulose fiber and PET fiber were available for making sucha good separator.
In the next study, we found that the nonwoven separator with cellulose fiber had a superior
performance to film type separator in heat resistance and the mixture of cellulose fiber and PET
fiber made it possible to provide the excellent nonwoven separator with higher wet strength andlower moisture affinity.

Development of Modified Cellulose Nanofiber Reinforced Resin Material
Daisuke Kuroki and Takafumi Sekiguchi
New Business Development Division, Seiko PMC Corporation
It is well known that the so-called shish-kebab structure could be observed whenpolyethylene（PE） is crystalized under shear flow. This characteristic is applied to the
manufacturing process of high strength PE fiber.

In this presentation, we discuss therelationship between mechanical properties, the crystal orientation and the injection-molding
conditions of the modified cellulose nanofiber (CNF) reinforced PE.
The modified CNF reinforced PE was injection-molded in various conditions, then, its

mechanical properties and crystal orientations were measured. Filling speed and cylinder
temperature strongly influenced the mechanical properties and the crystal orientations of thecomposites.
Development of PVOH for Paper Application
Keisuke Morikawa, Ayumu Yamamoto and Shigeki Takada
Kuraray CO., LTD.
Poly (vinyl alcohol) (PVOH) is widely used as a paper strengthening agent, stabilizer andbinder in the paper industry. PVOH also improves air permeability and grease resistance of
paper because a good film forming property of PVOH decreases the paper porosity. This reportwill refer to the properties of the coated paper with an outstanding hydrophobic modified PVOH.
The coated paper has better air resistance and higher water resistance compared to conventional
PVOHs. Furthermore the reason for the good air resistance was investigated from theperspective of affinity between PVOHs and paper, surface tension of PVOH aqueous solution,
and PVOH crystallinities. As a result, the PVOHs having the lower crystallinities provided thehigher air resistance. The lower crystallinity should ease the shrinking degree on the drying
process of PVOH aqueous solution and lead to a void-less film on the paper.
Impacts and Solutions of Starch on Activated Sludge Treatment
Takuji Yamamoto
Paper Chemical Business Division, Seiko PMC Co., Ltd.
Starch is considered one of the main factors in recent increase of drainage load.
In the stock preparation, the paper-making system, and the effluent treatment process, themetabolic activity of the microbes which utilize starch have great influence on the productivityof paper mills.
Starch is degraded by enzymatic activity of amylase, and metabolically converted to reserve
substances or extracellular polysaccharides of activated sludge.
Accumulation of reserve substances bring about aggravation of the treated water quality due
to the decrease in substrate removal speed of activated sludge, and superfluous generation of
extracellular polysaccharides cause foaming and deteriorated sedimentation property.
In this report, we demonstrated that continuous use of starch in paper-making system, especially
raw starch, greatly influence on activated sludge process.
So, we introduce the optimization of the paper making chemicals of a paper-making system

which raises the yield of starch and reduces drainage load, and the microbial preparation “MCseries” which improves activated sludge ability.
It should be essential for paper manufacture industry, which aims at saving resources and cost,
to take measure against starch load of the effluent treatment.
In this paper, analysis detailed about a paper-forming process is conducted, and the influencewhich increase of the drainage load by starch has to activated sludge processing, and its measure
are introduced focusing on the example of a mill trial of microbial product MC-003.

Plant Optimization with Control Loop Performance Monitoring―Metso PlantTriage―
Tomoshi Kono
Metso Automation K.K.
In recent years the plant operation with the small number of people is enabled mainly by theadvancement of DCS, and the staff is reduced as a part of rationalization and the labor saving.
In addition, the succession of the operation know-how of the plant becomes difficult for asimilar reason. On the other hand, with complicated advancement of the plant control, theworkload on operators and maintenance people are increasing. In such situation, it will bedifficult to pay more attention to facilities improvement / the optimization of the plant.

In this paper, I would like to introduce “Metso PlantTriage”, the software which monitors
performance of plant controls 24-7-365 and discovers the root cause of process problems withthe case example at the bleaching plant where we successfully reduced the chemical
consumption.
The word “Triage” used in the product name is the process of determining the priority ofpatients' treatments based on the severity of their condition in disaster medical care. This rations
patient treatment efficiently when resources are insufficient for all to be treated immediately. In“PlantTriage”, we apply technique of the “Triage” to prioritize the problems which were foundby 24-7-365 monitoring to optimize the plant in few resources effectively.

Cyber Security for Industrial Control System
Shoichi Doi
Solution Service Business Headquarters, Yokogawa Electric Corporation
In recent years, sophisticated cyber-attacks that target factories and plants have increased
even in production control systems. Due to such increases in threats and changes in theenvironment, the importance of security measures has become even more urgent. In fact, since2010 damage caused by malware infection has increased significantly.
However, this does not mean that blindly introducing security technology will be sufficient.
Unlike information systems in general, a stable, real-time operation on a 365 day/ 24 hour basis
is essential considering the sophisticated environment of control systems.
YOKOGAWA group support has taken a holistic approach to security measures in which
strategic defense-in-depth concepts are used to effectively evaluate potential risks, consider
technical measures and continuously update the system’s lifecycle. We believe improvements on
a continuous basis are important during operation. Measures are necessary to assess andmitigate the risks identified within the control system and to be better prepared to recover thesystem in the case of an emergency.
In YOKOGAWA group, by investigating and researching conditions in which security
measures are implemented in control systems and the practical use of the latest security
technology, we are currently developing effective solutions and optimal measures for a variety
of system configurations for different industries and applications. Over the lifecycle of thesystem, we are committed to providing the best possible solutions and services to ensure highreliability of systems and to provide customer-specific security measures so that stable operation
can be maintained.

Development of Cladding Process of Water-Cooled Boiler Panel and Example of Some
Characteristics in Actual Machine
Youichi Shiraishi and Yuuki Shimizu
Welding Alloys Japan Ltd.
In this paper, new maintenance method for cladding of water-cooled boiler panel is explained
from viewpoints of safety and cost-effectiveness. This method comes from our basic
maintenance philosophy which we call “Smart Welding TM ”for rebuilding. “Smart Welding”
is registered trademark for rebuilding and means that every elemental technique concerned
should be automated for speediness, safety and reliability.
Surface grinding and thickness measurement were herein automated with cladding process as
new technological trial. It can be safely said that this maintenance method will be promising forcladding of worn-out surface of water-cooled boiler panel with some improvements. The
cladding surface by this method is also shown in the actual machine (boiler) to be cost-effective
in its characteristics, that is to say, corrosion resistance, erosion resistance and lifetime. From

this result, it can be proposed that this maintenance method will be applied to worn-out surfaceof such boilers as ultra-super-critical pressure boiler, bio-mass boiler, waste-burning boiler,
recovery boiler etc.

The History of Technological Developments of the Paper Industry in Japan
Part 2: The Dawn of the Japanese Paper Industry
Kiyoaki Iida

In the latter half of the 19th century when the Meiji Restoration began, the paper industry inEurope and America had already put paper machine into practical use, and was developing a
new technology of producing pulp from wood. Those technologies conjointly became a modelof modern paper industry in the 20th century. When Japanese looked at paper mills in America
dynamically manufacturing paper, they made up their minds to do it in Japan. But, things did
not go well. After setbacks, they imported paper machines of medium size and manufactured
paper with rags cooked in alkali under coaching of highly paid foreigners. The first one began
operation in 1872. In a short period of time, Japanese learned know-how, dismissed them andamazingly made a copy of cylinder paper machine by themselves. The high ability of learning
new things and a fairly good level of mechanical engineering in those days were a base forsuccessive rapid progress.
Those who were credited at the dawn of the Japanese paper industry were young men who
studied in foreign paper mills, such as Masanori Onodera and Ichiro Murata, and Joichiro
Majima and Heizaburo Ohokawa who followed the formers. They were responsive to newtechnologies and introduced them positively to the industry, and their manner of diligence lasted
throughout the pre-war period.
The next part will review the growth of the Japanese paper industry.

Analysis of Quartz Content in Paper Using X-ray Diffraction and X-ray Microanalyzer
Toshitatsu Takei, Kazuyuki Tachibana, Toru Yaeda and Fumihiko Shimizu
Material Analysis Center, Oji Holdings Co., Ltd.
A new method of analyzing printing plate wear, which combines X-ray diffraction and X-ray
microanalyzer (XMA), was examined. When plate wear happened, the parallel incident X-ray
beam method, which is one of the techniques of X-ray diffraction, was used to analyze small
particles adhered to the blanket. As a result of the analysis, a small amount of talc (3MgO・
4SiO2・H2O) was detected. However, it seemed that only X-ray diffraction was not enough topresume that talc was a causative material because the talc concomitantly contained small
amounts of magnesite (MgCO3), dolomite (CaMg (CO3)2), quartz (SiO2) and chlorite ((Mg, Al)6
(Si, Al)4 O10(OH)8). This analytical method was further improved by combining it withelemental mapping observation of Scanning electron microscope（SEM).Using this method, thesmall amount of quartz in talc was found to be a factor in plate wear. Furthermore, therelationship between quartz content and plate wear in the experiment results matched previously
known plate wear evaluation data. This new analytical method, which is a combination of X-ray
diffraction and XMA, is a fast screening method that can detect up to 0.1 wt% quartz insamples.

The Wastewater Treatment Systems and Chemicals for the Reducthion of the COD/BOD
of the Papermaking Wastewater―The“Bio-Attach”,“COD Cutter”that Degrades and Treats COD BOD ―Kenta Furusho
NIPPON STEEL & SUMIKIN Eco-Tech Corporation
The normal activated sludge method is widely used a wastewater treatment technology
capable of advanced treatment at a low cost. However, the activated sludge method, by influent
overload, water temperature fluctuations, and an insufficient air supply,would be lead to suchproblems as a sludge bulking and the water quality deteriorations. The amount of wastewater ofthe paper mills is quite large and the content of SS is also high. The "Bio-attack" system willsolve problems mentioned above, because this system is a compact and a high-efficiency BOD
processing system.
The “COD Cutter” is a bioactivating substance that was developed in order to improve thebalance of microorganism groups in the aeration tank and prepare a proper environment for themutual symbiosis of the complex microbial communities. Its effect is enhanced by maintaining

the diversity of complex microbial communities by supplying microorganisum-activating
substances.
This paper introduces a brief the “Bio-Attach”/“COD Cutter”, its usage, and usage examples.

Overview of Deodorizing Equipment and Deodorizer Technology―Odor Control Will Be Settled in the Best Mix of Various Techniques―
Ken Nakatsuyama
Odor prevention Advisor, Japan Association on Odor Environment
Odor control technology is a very difficult technique unlike a prevention of various operation
and air pollution technology in the chemical industry. This is because it must process a very
low-concentrated blend shown by laws of Weber- Fefuner to a sense of smell level (the sense of
smell threshold). These techniques were developed based on an existing technique about
prevention of chemical industry and air pollution basically.
Offensive Odor Control Law constructed in 1972（S47）became The driving force that a many
Odor control technology was developed. However, all had good and bad points, and theperformance that I expected was not often provided. Solution to bad smell pollution includes
various approach, but it is the next pivot to be important.
1) Technique to control the radiation of the bad smell in the process (implant).
2)

Investigation into ingredient causing the bad smell.

3) The choice and the binational of appropriate deodorization and deodorization device.
4)

Investigation of construction maintenance cost and the environmental load.

The good Odor control technology will be provided from these technical Best mix.

Ozone Deodorization― Fight Against Odour, Wastewater ―Mitsuharu Nakajima
Nagano Bio Co., Ltd.
Odour issues often are present and prevail within Old and New Establishment, despite mostof them installed with various Waste Water Odour management products and equipment ….
However, Ozone Technology from Nagano Bio has been proven to be most effective against
Odour control which there are over 600 successful installations to date.

Applications where Ozone had been successful include Mushroom, Fish & Pig Farms, where
Growth Rate along with Yield increased by 30% and Bacteria/Viruses eliminated. Key
consideration for system adoption is Low Implementation Cost with Minimum Maintenancerequired.
Type of Ozone applications include:
Dry method with Ozone Gas - which is able to eliminate all airborne and surface bounded
Bacteria/Viruses and able to reach all areas of the closed room or space applied. Wet methodwith Ozone Mist or Water - which is able to eliminate most of the common Bacteria-Viruses
within 5 secs of contact.
Couple of key features and benefits of Ozone Solutions include:1)

It is available and generated on demand, therefore there is no need to keep any stocks

and no worries about product expiry compared to Chemicals type options.
2) There is no secondary pollution generated and therefore no need of subsequent cleaningor removal of Ozone Air or Water, as it will revert back to Normal Air & Water
after its main function.
3)

It eliminates Bacteria and Virus with its strong Oxidation to break down the Cell Walls of

the Bacteria and Viruses.
Included in the details are 2 installation references for Nagano Bio’s 30 years of experience
which includes- The proper process to first understand the issue,- The scientific way to measure and show results,- Setting the expectation,- Post installations follow-up & MaintenanceOzone has been proven to be the most effective reducing levels of BOD, COD, VOC, SS,

About Act on Rational Use and Proper Management of Fluorocarbons― Thing that You Must Do as a Manager of the Apparatuses―
Tsutomu Osawa
Japan Association of Refrigeration and Air-Conditioning Contractors
The refrigeration and air conditioning equipment is used now in every place and becomes
indispensableness supporting a comfortable living.
Whereas, Fluorocarbon has been used as a refrigerant of the refrigeration and air conditioning
equipment, fluorocarbon was pointed out influence on ozone depletion.
Therefore we pushed forward reduction along Montreal Protocol in all the countries of theworld, and planned the switch to HCFC alternatives.
However, as for the HCFC alternatives, movement of the regulation reinforcement of the
HCFC alternatives begins because there is influence to give global warming more than several
thousand times from several hundred times of carbon dioxide (CO2).
In Japan, full-scale Fluorocarbons measures began because of the Fluorocarbons Recovery
and Destruction Law was promulgated in June, 2001, and the law was revised in June 2006.
Because this law proved that there are many leaks of Fluorocarbon during the use of theapparatus, large revision is performed in June, 2014 and changes the name the Act on Rational
Use and Proper Management of Fluorocarbons is enforced from April, 2015.
This seminar's contents explain about "a standard of Re-filling" specified as an observancematter of the managers (owner) of the apparatuses by the process of conventional Fluorocarbon
measures, and this time's newly amended point mainly on so-called "thing that you must do as amanager of the apparatuses".

Practice Point of Risk Communication
Shiro Kobayashi
Chemical Advisor
Under PRTR Law(Law concerning Pollutant Release and Transfer Register), targetedbusiness operators are required to confirm the released/transferred amount of designatedchemical substances, and report them to the government every year. Report data can be viewed
by stakeholders such as local residents. Between the operators and stakeholders, the process of
information exchange and mutual understanding of the published data is referred to as "Riskcommunication". In this presentation, a description will be given of the practice point to asmooth risk communication in the pulp and paper manufacturing industry.

The History of Technological Developments of the Paper Industry in Japan
Part 3: The Growth of the Japanese Paper Industry
Kiyoaki Iida

In thirty years from the Meiji Restoration, the paper industry in Japan entered into its
progressive era, benefiting from the efforts by pioneers and supported with a fair cultural levelof mill workers. Paper machines of large size equipped with newest technologies were imported,
instead of medium size ones at the beginning, in about ten year-delay from abroad. The newtechnologies were implanted on old paper machines. Several domestic machine builders also
started their business, copying the imported ones at first. In 1916, they made more paper
machines in number than the imported, though mostly cylinder machines, and the sum of theirwire widths was larger than that of the imported. Ohshima Steel Works, among them, evensupplied a newsprint machine of the largest size at that time. The active capacity expansion was
to supply the demand increasing in printing and carton making. In other words, Japan itself wasrapidly expanding the economy.
Engineers most of whom were alumni of Tokyo Higher Technical School (a predecessor ofTokyo Institute of Technology) contributed to the expansion. They had chances to visit mills
abroad while young and played important roles in introducing new technologies and also in milloperations.
Nishi, at his thirties, toured mills in the U.S. and Europe for 8 months in 1925, saw decline ofFrance, stagnation in the U.K., recovery of Germany, growth in Sweden, wood shortage in the
U.S. and newsprint production in Canada that was exported to the U.S.
He even said that it would be possible for Japan to compete to the U.S. and Canada
economically by improving facility and technology.

This research was aimed at improving the utilization of waste generated by the palm oil
industry by identifying the conditions needed to make fibers suitable for products such as
paperboard and fiberboard from the empty fruit bunch (EFB) of oil palm (Elaeis guineensis).
For this, the chemical pretreatment conditions needed to mechanically produce a pulp for
paperboard were studied, as well as the effects of varying these conditions on the fiber
properties. The optimum conditions to achieve the highest paper strength were found to be a
NaOH dosage of 2 %, pretreatment time of 2 h at 121 °C and refiner disk-clearance of 0.10 mm.
This EFB pulp exhibited similar tensile and tear indices to a pulp prepared from an old
corrugated fiberboard box, and on the basis of this, it was considered acceptable for use incorrugating medium. Subsequent fabrication of fiberboard and clarification of its resistance tofungal attack found that the mechanical properties of EFB fiberboard made from unrefined
fibers are lower than Japanese Industrial Standards; however, its resistance to brown-rot andwhite-rot fungus is better than that of board made from sugi (Cryptomeria japonica).
