Evaluation of the spray stability on liquid injection in gas–solid fluidized beds by passive vibrometric methods
Authors: Briens Lauren , Book Garret , Albion Katherine , Briens Cedric , Berruti Franco
Published: April 2011

For some operations, such as fluid coking, gas atomised liquid feed must be injected via spray nozzles into gas–solid fluidized beds. A stable or non‐pulsating spray with a controlled droplet size is desired. The spray stability of various gas–liquid pre‐mixer and nozzle combinations was determined in open air conditions through analysis of vibration measurements on the upstream conduit with an accelerometer correlated to physical downstream spray measurements. The open air vibration measurements did not correspond to vibration measurements while spraying into a fluidized bed due to external vibrations from the fluidisation. The vibration measurements, however, can provide a relative ranking of spray stability of various gas–solid pre‐mixer and nozzle combinations for similar fluidisation conditions. In addition, the gas to liquid ratio (GLR) and the gas properties were all found to affect spray stability.
Direct estimation of residence time from input and output data
Authors: Soltanzadeh Ali , Bennington Chad P. J. , Dumont Guy A.
Published: April 2011

Residence time is a well known and widely used concept in the process industry, and its estimation is often needed to model or optimise a process. This study will demonstrate a new method using suitable measures of input and output data. There are two distinct characteristics of this method: it is not necessary to estimate the residence time from an explicit model, and the constraints on the excitation of the input signal are not as restrictive as common methods. © 2011 Canadian Society for Chemical Engineering

Published: April 2011

This article presents a experimental study on the removal of hydrogen sulphide (H2S) from high salinity wastewater by emulsion liquid membrane (ELM). The ELM contains diethanolamine (DEA) as carrier, kerosene as solvent and span 80 as surfactant. The fundamental parameters (viz. surfactant concentration, carrier concentration, strip phase concentration, phase ratio, agitation speed and time) affecting the removal of H2S were investigated to select the optimum combination of process parameters. The results showed the optimal governing parameters were: inner phase NaOH aqueous solution 2.0 wt%, Surfactant (span 80) 5.0 vol%, carrier (DEA) 6.0 vol%, treat ratio 1:5, agitation speed 250 rpm, agitation time 15 min, respectively, and removal efficiency of 97.3% was achieved. © 2011 Canadian Society for Chemical Engineering

Authors: Mansour M. A. , Ahmed Sameh E.
Published: April 2011

This paper presents a numerical investigation of laminar mixed convection cooling of heat source embedded on the bottom wall of an enclosure filled with nanofluids. The transport equations for a Newtonian fluid are solved numerically with a finite volume approach using the SIMPLE algorithm. The influences of governing parameters, namely, Rayleigh number location and geometry of the heat source, the type of nanofluid and solid volume fraction of nanoparticles on the cooling performance is studied. The present results are validated by favourable comparisons with previously published results. The results of the problem are presented in graphical and tabular forms and discussed. © 2011 Canadian Society for Chemical Engineering
Hydrodynamics and flow regimes in turbulent bed contactor with non‐Newtonian liquids
Authors: Bruce A. E. R. , Swathi P. , Krishnaiah K. , Sai P. S. T.
Published: April 2011

The flow regimes normally encountered in a turbulent bed contactor (TBC) are static, partially fluidised, completely fluidised and flooding regimes. Experiments were conducted in a TBC operating in Type I mode to identify the flow regimes with non‐Newtonian liquid. Flow regime transition velocities were obtained from the pressure drop and bed expansion measurements at various operating and geometric variables. The variables include apparent viscosity of the liquid, gas and liquid velocities, size and density of the particles, and static bed height. The effect of the above variables on delineation of flow regime transition was studied. Based on the experimental data, correlations were proposed for predicting the transition velocity from one regime to the other. The influence of the variables on regime transition velocities is more or less similar to that observed for Newtonian liquids. © 2011 Canadian Society for Chemical Engineering

A study of decoupling with skeleton matrix in two‐degree‐of‐freedom generalized minimum variance control
Authors: Mori Yasuchika , Takaki Akihiro
Published: April 2011

There are many multi‐input multi‐output (MIMO) systems in chemical plants, and they have multiple time delays of different length in each input and output pair. This paper explains a two‐degree‐of‐freedom (2DOF) control system based on generalized minimum variance control (GMVC) for MIMO systems. It can improve the tracking performance with respect to the reference signals and the response properties for the disturbance. The states between the sampling period can be expressed by using the modified z transform to take account of multiple time delays. Additionally, a tracking controller is designed to decouple the plant. © 2011 Wiley Periodicals, Inc.

Application of improved genetic algorithm to service restoration problem for distribution systems
Authors: Michibata Ikuo , Aoki Hidenori
Published: April 2011

The problem of recovery from power‐system failures is the problem of handling operations that make it possible to supply power from other lines in response to power‐system failures or construction by switching between the opened and closed states of sectionalizing switches. Considerable research has already been conducted with regard to this issue. This paper addresses the issue of determining target systems for final recovery in cases when some sections remain subject to power failure (i.e., sound bank capacity < load capacity). For this purpose, intersection is conducted only for parameters within such power‐failure sections. In such research, calculations are implemented by setting a value of 2 to the sectionalizing switches of a single parameter. In addition, when the state of a sound section changes due to mutation improvements, the method of simultaneously changing the selected points and neighboring sectionalizing switches is applied. It is clear that the proposed method, consisting of conventional GA only, is superior in terms of average fitness values. © 2011 Wiley Periodicals, Inc.

Evaluation of the plug‐in hybrid electric vehicle considering learning curve on battery and power generation best mix

Published: April 2011

The plug‐in hybrid electric vehicle (PHEV) is a technology intended to reduce CO2 emissions in the transport sector. This paper presents scenarios that show how widely used PHEVs will be in the future, how much CO2 emissions will be reduced by the introduction of PHEVs, and whether there will be serious effects on the power supply system. PHEVs can run on both gasoline and electricity, and therefore we evaluate CO2 emissions not only from gasoline consumption but also from electricity consumption. Consideration of the distribution of daily trip distances is important for evaluating the economical benefits and CO2 emissions resulting from the introduction of PHEVs. Also, future battery costs are very important in constructing PHEV growth scenarios. The growth of the number of PHEVs will make battery costs lower. Thus, we formulate an overall model that combines the passenger car sector and power supply sector, taking account of the distribution of daily trip distances and incorporating a learning curve for battery costs. We use the iteration method to provide a learning curve that is nonlinear. Therefore, we set the battery cost only in the first year of the simulation: battery costs in the later years are calculated in the model. We focus on a 25‐year time period in Japan, starting from 2010, and divided into 5 parts (1st to 5th). The model selects the most economical combinations of car types and power sources. © 2011 Wiley Periodicals, Inc.

A study on condition assessment method of gas‐insulated switchgear. part II. influence of moisture in the SF6, detection of a partial discharge on a spacer, repetition discharge and overheating by incomplete contact
Authors: Shinkai Hiroyuki , Goshima Hisashi , Yashima Masafumi
Published: April 2011

Rationalization of the maintenance of gas‐insulated equipment under operation and lifetime extension based on the results of appropriate diagnosis are necessary to reduce the cost of gas‐insulated equipment. Therefore, condition‐based maintenance (CBM) is required and accurate methods for observing the inside of equipment are important. In this report, we describe a diagnosis method that can be used for actual gas‐insulated equipment, such as to assess the deterioration of the spacers made of epoxy resin and to detect loose connections in the central conductor. The principal results are summarized as follows:

(1) The quantity of decomposition gases depends on the moisture and magnitude of the partial discharge. However, decomposition gases were detected even if SF6 had low moisture content (less than 100 ppm) similar to that used in actual equipment. This means that our method can be applied to actual equipment.

(2) It became clear that CF4 is a typical gas generated by partial discharge on the spacer surface. Therefore, it is possible to diagnose spacer deterioration by monitoring CF4.

(3) Decomposition gases (SF4, SO2, SO4, SO2F2) were generated by impulse breakdown, which was assumed to be due to repetition discharge caused by insulation failure and loose connections.

(4) SF6 gas was assumed to be exposed to a loose connection and was heated from room temperature to 800 °C, and the generated decomposition gases were analyzed by FTIR in real time. As a result, the decomposition gases were generated at temperatures above approximately 500 °C in a heating time of 1.5 minutes. Therefore, a loose connection can be detected by analyzing the decomposition gas. © 2011 Wiley Periodicals, Inc.

Published: April 2011

In order to improve the reliability of electric power systems, it is important to reduce malfunctions of relays or faults of low‐voltage control circuits in substations due to switching and lightning surge. However, it is not sufficient to study the intrusion of surges into low‐voltage control circuits. We studied the terminal voltage of the control panel and analyzed the intrusion route of surges in substations. © 2011 Wiley Periodicals, Inc.

A method for haptic motion abstraction and display based on action force directionality
Authors: Hyodo Shoyo , Ohnishi Kouhei
Published: April 2011

Robots working in an unknown environment or a human environment have been investigated for years in the field of motion control. For the next‐generation robots, human and robot interaction technologies are needed. In particular, abstractions of human motion and motion display technologies are important. This paper proposes a method for haptic motion abstraction based on action force directionality. The action force is measured by using a master–slave robot hand system which is bilaterally controlled. Human motion is abstracted as action modes and action ratios, which are calculated from the action force directionality. Action modes express action force directionality, and action ratios express the amplitude of each action mode. Action modes are valid for motion preservation, identification of humans, and motion display systems. Thus, as one of the application of action modes, a method for motion display is also proposed. A motion display control system is designed based on action modes and action ratios. This control system presents the desired action force directionality as a velocity response depending on the human action force. The validity of the proposed method is shown by the experimental results. © 2011 Wiley Periodicals, Inc.

Published: April 2011

The reactivity of both the monoanionic and dianionic forms of bis(diphenylthiophosphinoyl)methane (2– and 22–) as well as the dianion of tetraisopropyl methylenediphosphonate(32–) was investigated towards the same CoII precursor CoCl2. Monoanion 2– coordination yields a homoleptic zwitterionic CoII complex. However, both dianions (22– and 32–) give the same overall structure with a square Co2C2 core. Structures of all of the complexes have been confirmed by full NMR spectroscopic analysis and X‐ray diffraction. Furthermore, DFT calculations have been carried out to rationalize the stability of such species.

The total synthesis of plagiochin D, a macrocyclic bis(bibenzyl) compound isolated from the liverwort plagiochila acanthophylla, has been accomplished. Closure of the key 16‐membered ring, which contained biphenyl ether and biaryl units, was achieved in good yield by an intramolecular SNAr reaction. The Suzuki and Wittig protocols proved to be powerful tools for the construction of a linear precursor that was crucial for ring cyclization.

Published: April 2011

The synthesis of two new α‐aminophosphonic acids, namely (2S*,3aS*,7aS*)‐ and (2R*,3aS*,7aS*)‐octahydroindole‐2‐phosphonic acids, is described. They are analogues of phosphoproline with a cyclohexane ring fused to the pyrrolidine moiety. The ring junction has cis stereochemistry in both cases, but the two compounds differ in the relative orientation of the cyclohexane and phosphonate moieties. The two amino acids were prepared from a common starting material following stereodivergent routes that provide the desired stereoisomer with complete stereocontrol. The relative configurations of the compounds synthesised were confirmed by X‐ray diffraction analysis.
