title: Multi-criteria decision analysis (MCDA) of iron making technology in Thailand

description: The purpose of this study is to evaluate and prioritize iron making technology in Thailand by using Multi-Criteria Decision Analysis (MCDA). The scope of assessment was focused on three iron making technologies are blast furnace (BF), corex and midrex. Three iron making technologies were evaluated by using bipolar analytical hierarchy process (BAHP) based on three main criteria and nine sub-criteria. The qualitative data and quantitative data were collected from government sector, private sector, education sector and institute sector. The qualitative data of relative preferences were changed to quantitative data by expert judgment following classical AHP method. The results showed that in economic criteria BF technology had the positive preference due to high net profit. The most preferences of iron making technology in terms of environmental concerns and technology criteria belonged to midrex technology due to use natural gas as fuel as well as lower environmental impact. The results from final evaluations based on technology, economic and environment aspects using the bipolar analytical hierarchy process (BAHP) exhibited that BF technology was the most preference of iron making technology in Thailand (48%), followed by midrex (28%) and corex (24%) respectively.

title: Prospects for UBC (upgraded brown coal) technology

description: Utilization of low rank coal has been limited so far, due to its high moisture content, low calorific value and spontaneous combustibility. Some lignite has the feature of low sulfur and low ash content. Therefore, it can be turned into an attractive fuel coal, if it is upgraded, using an economical dewatering method. Kobe Steel has been developing upgraded brown coal (UBC) technology since 1980s. By applying the UBC technology for high-moisture coal (total moisture 50wt% or more), it is possible to obtain product moisture 0wt%. It may also be applied to the dehydration of biomass waste Kobe Steel was promoting a UBC demonstration plant (600tons-UBC/day) project, it was completed successfully, and this technology is now ready for commercialization. UBC process and the method for utilization of UBC products are introduced in this paper.

title: The effects of a bulking agent and aerobic system on chicken manure composting using "Serial self-turning reactor (STR)" technology

description: This research aims to evaluate the roles of a bulking agent as recycled compost and aerobic system in a composting technology called "serial self-turning reactors (STR)", using chicken manure as a substrate input. Group A was composted with sawdust in the partial aeration. While group B was processed with a forced aeration at 0.5 lit/min/kg organic matter, and the recycled compost was added beside sawdust. Each group was tested at different C/N ratios caused by different mixing ratios. The temperature was recorded every 5 minutes at 3 positions: middle, bottom and wall area of each reactor. The compost with group A did not meet the pathogen requirements in any cases and the temperature simply followed ambient temperature. Conversely, the temperature in all cases of group B rose up. Only 2 in 3 cases in group B met the thermophilic phase. And the other case, which did not reach into thermophilic phase, started with the largest amount of sawdust. Recycled compost provided the suitable porosity and maintained the beneficial microorganisms by supplying oxygen from the airflow.

title: Electrochemical oxygen reduction reaction rate in polymer electrolyte fuel cell

description: Since optimization of the catalyst layer structure is necessary for reducing the cost of polymer electrolyte fuel cell (PEFC), formulation of the oxygen reduction reaction (ORR) rate in the cathode of PEFC is highly required for carrying out the numerical simulation for the design purpose.  The ORR rate was measured with reducing the catalyst layer thickness for lowering the mass transfer resistance to oxygen, proton, and electron.  Dependencies of the ORR rate on the oxygen partial pressure, relative humidity, and cell voltage were analyzed.  The rate was of the first order with respect to the oxygen partial pressure up to 220 kPa.  The first-order reaction rate constant was an exponential function of the cathode electromotive force.  The exponent and preexponential factors were different in high and low cathode electromotive force regions.  These kinetic parameters were formulated as functions of relative humidity.  It was found that the exponent and preexponential factors were in strong correlation regardless of the relative humidity but depending on the cathode electromotive force region.

title: Carbon footprint of educational institute: case study at King Mongkut's University of Technology Thonburi

description: This study aims to calculate GHG emission and removal from the related activities in KMUTT during 2011-2013. The scope of assessment was focused only in KMUTT Bangmod Campus, excluding resident halls and Darunsikkhalai School for Innovative Learning (DSIL). The GHG calculation in this study followed the guideline of carbon footprint for organization which divides GHG sources into 3 scopes such as direct GHG emission, indirect GHG emission from purchased energy and other indirect GHG emission (TGO). The activity data were collected from various sources. Fuel consumption and purchased electricity were provided from the Building and Ground Management Institute and Energy Environment Safety and Health (EESH). Water consumption, office supplies and wastes were provided from Treasury office and Prabkaya Recycle Company (Outsource). Results shows that total GHG emissions of KMUTT in 2011-2013 were 11,410, 11,072 and 11,275 tonCO2e/year, respectively. The major sources of GHG emission were purchased electricity accounting for 87.45% of the total emissions, followed by waste (10.94%), transportation of KMUTT vehicle (1.23%), office suppliers (0.34%) and water (0.04%). In addition, GHG removal from waste recycling program (GHG offset) accounted only for 1% of the total GHG emissions. Thus, net GHG emissions per capita for 2011-2013 were 0.57, 0.54 and 0.56 tonCO2e/year/staff and student, respectively. Electricity consumption and waste generation were the hotspots of GHG emission in KMUTT. Accordingly, the potential GHG reductions should be paid more attention to electricity conservation, waste utilization (waste composting) and waste reduction (3Rs).

title: Synoptic Circulation and Ozone Pollution over Two Major Cities in Eastern Thailand

description: In this work, a back-trajectory modeling approach was applied to study the impact of synoptic circulation and longrange transport of ozone (O3) and its precursors on surface O3 level in Chon Buri and Rayong, two highly industrialized and urbanized cities in eastern Thailand. For each city, daily kinematic trajectories with backward migration of 3 days were simulated for 16 O3 seasons (Nov-Apr) over 1997-2012, using FLEXTRA model. The K-means clustering method was then used to group all simulated trajectories into a number of unique clusters. The clustered trajectories and their corresponding citywide daily daytime (10-18 LT) maximum O3 (DDMXO3) were statistically analyzed. A total of five trajectory clusters were equally found for each city and the overall cluster patterns in both cities were similar. The corresponding DDMXO3 values were found to be significantly different (p-value &lt;0.05, Tukey's test) in almost all pair of trajectory clusters in each city. Furthermore, for both cites, the average DDMXO3 found to be relatively large in trajectory clusters with continental origin as opposed to maritime cluster with relatively low values. It was also found that low-altitude trajectories are likely to be linked with higher O3 than high-altitude ones. These findings indicate the potential association between O3 and synoptic circulation.

title: The possibility of making water retention basins ("monkey cheeks") in the Gulf of Thailand as a long-term solution for flooding

description: After the devastating floods of 2011, the floodwaters in areas of upper Thailand flowed down the course of the natural flood plains of the Chao Phraya river basin. Their entrance into the Gulf of Thailand was slow. This occurred because of many factors that arose as the government and other stakeholders were attempting to ameliorate the problems. At least three major factors related to the drainage of water into the Gulf should have been considered by the government in order to address the issues and to achieve full protection from flooding. As it is, the cost of damages reached 1.44 million baht. Taking into account the experiences from 2011, we must keep in mind the following three issues: the amount of surface that bears the floodwater (the retention basins, or "monkey cheeks,"), the drainage of the extra water into the ocean proceeds at a slow pace, and the water level in the ocean is rising due to global climate change and storms in the Gulf of Thailand. In-depth research has not yet been carried out about the phenomenon of rising sea levels in Thailand.  This paper presents trends of thought on the possibility of making water retention basins in the Gulf of Thailand at the river basin of the Chao Phraya River in order to target the problem of the drainage of water into the ocean with a fully systematized solution. The concept of the water retention basins, or "monkey cheeks," comes from the research and ideas of King Bhumibol Adulyadej combined with local knowledge about living with water in ancient cities of the past. This approach will be enhanced with technologies related to dams, water locks, and modern, floating architecture, in addition to techniques related to material use and modern construction. Furthermore, the propose methods will address flooding challenges without or less damaging the coastal ecosystem and could also help with the problem of coastal erosion in Bang Khun Thian. Also the multidisciplinary assessment including the biosphere environment condition and socio-cultural aspect along the coastline shall be taken into account to support the concept.

title: Steam gasification of iron-loaded biochar and subbituminous coal mixture

description: This study aims to investigate the effect of the addition of the iron-loaded biomass pyrolysate (Fe-biochar) on the steam gasification of Indonesian Adaro sub-bituminous coal.  The amount of hydrogen evolved from the steam gasification of the mixture of Fe-biochar and Adaro coal at 800?C for 60 min was much higher than that from the steam gasification of iron-loaded Adaro coal.  From the result that the specific reaction rate did not decrease during the steam gasification of the mixture of Fe-biochar and Adaro coal, the iron catalyst on the biochar was found to be relatively stable in the steam gasification.  The activity of iron catalyst was discussed by the differences in the chemical form and the crystallite size of iron catalyst.

title: Effects of the geometry of the air flowfield on the performance of an open-cathode PEMFC

description: The present work performed an experimental study on a forced-air open-cathode PEMFC. The aim of this work is focused on the effect of the geometry, in terms of the flow area and the shape, of the cathode channel on the performance of the PEMFC. The single-cell open-cathode PEMFC with the active area of 100 cm2 is designed and fabricated for the study. A fan is used to supply an adequate flow rate for cooling and chemical reaction as well as to supply the pressure to overcome the pressure drop across the air flow channel. At low current density, the same performance was found regardless of the flow area and the aspect ratio. The performance at 0.6 V is about 180 mA/cm2. At higher current density, the performance increases with the higher aspect ratio. In contrast, the different flow areas exhibit mostly insignificant effect on the performance of the fuel cell. However, the larger flow area is more preferable due to the net system efficiency and the lower production cost.

title: HYDRATION AND MICROSTRUCTURAL PROPERTIES OF CEMENT PASTE CONTAINING NANO AND MICROSILICA

description: The influence of nano- and microsilica addition on ordinary Portland cement (OPC) pastes has been studied in terms of hydration and microstructural properties. Three different combinations of nano- and microsilica mixes were used. A constant water-binder ratio of 0.35 was maintained throughout the experiment. All samples were tested for initial and final setting time and compressive strengths were determined at the age of 3, 7, 28, and 90 days of hydration. The hydration products were examined by SDT and XRD analysis at various curing ages. The inclusion of nano- and microsilica reduced the initial and final setting time significantly, increased the compressive strength of hardened cement paste after 7 days of hydration, and reduced the amount of calcium hydroxide in the hardened paste compared to mixes without these nanoparticles.

title: Experimental investigation of optimum blend ratio of deodorant powder for removal of TVOCs from a foundry plant

description: Foundry is an important industrial process for making metal products in desired shapes especially for complex models that might not be economical to manufacture by other methods. However, the process also generates vast amounts and various types of air pollutants such as odor-causing volatile organic compounds (e.g., hydrogen sulfide, ammonia, etc.) and particulate matters. Therefore, development of technique that can efficiently eliminate these emissions released from the process is regarded as an essential research. For the purpose to simulate an existing pollution control system, in this study, a spray adsorption system was designed to work with a bag filter so as to remove total volatile organic compounds (TVOCs) and dust particles simultaneously actually emitted from the de-molding process of a foundry plant. Maximization of process efficiency, by finding optimum blend ratio of deodorant powders selected i.e. activated carbon (AC) and zeolite (ZL), was the focus of this research. Seven mixing ratios of AC and ZL were tested in several conditions. Through the experiments, TVOCs removal efficiency of more than 95% for all conditions was obtained from the adsorbent that composed of 80% AC (800 mesh) and 20% ZL (300 mesh) by mass.

title: Updated mobile source emission factors in Thailand

description: In response to emission control strategies, the Royal Thai government by the Pollution Control Department (PCD) is obligated to estimate emissions from on-road vehicle fleets. Estimates of vehicle emissions are obtained by multiplying an estimate of the vehicle kilometer traveled (VKT) by a given class of vehicles by an appropriate emission factor (EF). The EF is defined as the estimated average emission rate for a given pollutant for a given class of vehicles. EFs are based on average speeds, ambient temperature, diurnal temperature range, altitude, fuel volatility and I/M programs; changes in these input assumptions alter the resulting emission factors. The different class of motor vehicles were conducted emission tests in the Automotive Emission Laboratory (AEL),Thailand and pollutants such as CO, HC, NOx, PM and Air Toxics were measured under different situations such as fuel type and its quality, engine technology and driving speed and patterns for example. The emission results will be developed appropriately to calculate as emission factors of each vehicle types in Thailand. There are 4 mainly motor vehicle emission factors developed for 4 class of motor vehicles which are motorcycle (MC),light duty gasoline vehicle (LG),light duty diesel vehicle (LD) and heavy duty diesel vehicle (HD). Those emission factors will be applied to estimate mobile source emission loading in study areas which will be investigated with traffic data yearly. The outcomes will be supported in further appropriated policy and measure to manage and control air pollution problem in Thailand particularly mobile sources.

title: The co-flow planar anode-supported solid oxide fuel cell micro-scale model

description: Solid Oxide Fuel Cells (SOFCs) are of great interest due to their high energy efficiency, low emission level, and multiple fuel utilization. In this study, a mathematical model of a co-flow planar anode-supported SOFC has been developed. The model simultaneously solves mass transport equations coupled with electrochemical reaction, as well as transportation of electrons and ions through the respective spherical shaped electron and ion conducting particles inside the electrodes. The influence of electrode microstructure on cell performance was investigated. The investigation confirmed the strong effects of microstructure geometry, especially the electrochemical active surface area (Av), on the SOFC performance. The largest Av is achieved when the size and solid volumetric fraction of ion and electron conducting particles are equal. The model was validated with existing experimental results from the available literature.

title: Experiments on lignite combustion in a circulating fluidized-bed reactor

description: In this study, a circulating fluidized bed (CFB) (0.15 m i.d. and 5.4 m high) was used to investigate the combustion characteristics, including riser temperature, major pollutant emissions (CO, SO2 and NO) and combustion efficiency, of Thai lignite. The combustion experiments were carried out at different excess air ratios (?0 = 0.97-1.50). The experimental results from combustion tests demonstrate that either or both the resulted change in the riser temperature in the CFB riser and the O2 availability for combustion affected the combustion efficiency (Ec) and formation of CO, SO2 and NO. The combustion efficiency varies between 96.0-97.4% depending on the excess air ratio.

title: MECHANICAL PROPERTIES OF GEOPOLYMER CONCRETE WITH MINERAL ADMIXTURES

description: Concrete has contributed to the development of modern architectural culture, but the cement as an adhesive agent for concrete produces large amounts of carbon dioxide emissions into the air during the manufacturing process. This study researches the practical use of structure, through the verification of structural stability, for geopolymer concrete. This is part of the development of core technology for greenhouse gas emission reduction by reducing energy consumption in construction, an industry that occupies 25% of the total energy consumption in South Korea. According to the experimental results of chemical reaction (i.e., acid reaction, sulfate resistance reaction and corrosion caused by sodium chloride) of fly ash-based geopolymer concrete, the theory and SEM analysis demonstrated that geopolymer concrete was acid resistant, sulfate resistant, and resistant to corrosion caused by sodium chloride. The basic properties were understood through qualitative analysis of a geopolymer concrete specimen using SEM, and through a study on the practical use of structure by verifying structural stability for geopolymer concrete, as part of development of technology. After future experiments and tests, the best geopolymer concrete ratio and curing method will provide a guideline.

title: A STUDY OF MAINTENANCE METHODS OF DETERIORATED CONCRETE STRUCTURES WITH A RISK MATRIX

description: In this study, a risk matrix for maintaining the deteriorated RC structures was proposed, in which the difference between the results based on investigation and the actual performance was regarded as risk. The risk matrix was defined as the relation between the degree of material deterioration and the level of influence on the structural performance. This matrix was characterized by involving the range of risk reduction that serves as an index for determining the need for repair. In addition, survey results from an actual RC structure that had undergone the combined damage of frost and salt for more than forty years in Hokkaido were applied to the proposed risk matrix.
