  13. The purposes of the present research are to develop home-manufactured fabrics that should be of good quality and not expensive, and to transfer the filtration technology to the industry that should be properly linked to the corresponding fabric filter system. In the previous paper, the performance of glass-fiber fabrics recently developed by a Korean company, Kangnam Ind. Co., Ltd. in Pusan, was tested at bench scale unit in comparison with that of imported ones. As a second stage, pilot scale works were designed in order to obtain proper installation and operation conditions with home-manufactured fabrics. At first, sever field conditions were collected and reproduced at a pilot scale test unit equipped with home-manufactured fabric and typical imported glass fabrics. which is the scope of this paper. More wide variations of relevant parameters are currently experimented at the same test unit. Field test is also conducted to demonstrate the adaptation of home-manufactured fabrics to real coal-fired boilers.

  13. The performance of a fabric filtration technology is superior to those of other dust removal technologies. This technology provides higher dust removal efficiency than any other dust removal technologies and is simultaneously capable of removing sulfur and hydrogen chloride. Therefore, this technology can be applied for the purpose of flue gas cleaning in various industrial processes. However, fabric filtration facilities installed in domestic industries have not been efficiently used due to the following reasons:
    1) poor knowledge of dust and fabric characteristics,
    2) inadequate matching of dust and fabric,
    3) unestablishment of the design condition in each industrial processes. In addition, since most fabrics are imported, they are expensive and the manufacturing method and structure of them cannot be easily changed to meet the characteristics of dust. In this research, firstly it is attempted to develop high performance domestic filter fabrics suitable for the dusts generated in various dust-generating processes, combustion processes and establish operating conditions for each dust in order to obtain satisfactory performances. Secondly, it is attempted to develop a high efficiency fabric filtration technology through the standardization of the design technology and the establishment of the optimum operating conditions.

  13. Baghouse is the most widely used equipment for the removal of dust from flue gas. The objective of this research project is to develop a process which could simultaneously remove SO2 and dust using a baghouse from the flue gases generated in various coal combustion or incineration facilities. This process involves injection of humidification water and dry sorbent, which is usually hydrated lime, into the flue gas between the air heater and the fabric filter. The injection of humidification water is for the humidification of the flue gas by a fine wate mist. Hydrated lime is injected into the flue gas after most of the water mist had evaporated. SO2 removal reaction occurs in the duct and in the fabric filter. Depending on the operating conditions, more than 90% of the SO2 can be removed in the fabric filter alone due to the reaction with unreacted hydrated lime. The major process variables for the SO2 removal reaction in the fabric filter are filtration velocity, sorbent/SO2 mole ratio, and humidity. Currently optimization of these variables are under study.

This process involves injection of humidification water and dry sorbent, which is usually hydrated lime, into the flue gas between the air heater and the dust collection unit. The injection of humidification water is for the humidification of the flue gas by a fine water mist. Hydrated lime is injected into the flue gas after most of the water mist has evaporated. SO2 removal reaction occurs in the duct and additionally in the dust removal unit, which is usually ESP or a fabric filter. The major process variables in this process are sorbent/SO2 mole ratio, SO2 concentration, humidity, and residence time of the flue gas. The effects of these variables on the process performances are under study.

  13. Korea generated 165,000GWh of electricity in 1994. The energy sources used to generate the electricity include oil(25%), LNG(12%), coals(25%), nuclear(35%), and hydro(3%). Being an energy-poor country, Korea generates 95% of its electricity by using the imported energy sources. The long-term projection indicates that the electricity generation in Korea will reach 54,000MWe in 2006 and that by then, about 30% of total electricity will be generated using coals. The objective of this study is to develop an optimum rejection process of sulfur and ash from the high-sulur, high-ash coals that may be imported, basically using column flotation technology, to meet such long-term demand.

  13. Advanced cyclone combustion systems are one class of the emerging clean coal technologies being developed to improve the quality of the nation's air, while increasing the use of abundant energy resource. In cyclone combustion system, coal is burned at a temperature high enough so that coal ash melts and turned to liquid. This liquid then flows down the combustor walls and is collected and withdrawn. Therefore, there are few soild ash particles to pass out of the chamber with the hot gases. In addition, the sulfur found in most coals can also be removed at this point. Calcium compounds are introduced into the chamber, where they combine with the sulfur. The resulting sulfur compounds melt and join the slag. Also, because a cyclone combustor operates fuel-rich in the primary zone it will suppress NOx formation. The hot gaseous combustion products formed are ducted into the retrofitted boiler, where sufficient air is added to complete combustion of these gases.
    The object of this study is to develop cyclone combustor by our own efforts, then we made two staged cyclone combustor which is bench scale. The result of burning test, the proper air ratio is about 1.0 and coal feeding rate were more then 30 kg/hr. In the case of Peco-semi coal combustion, it was certified that carbon conversion efficiency was more than 95% and ash removal efficiency in a state of fusion of slag was about 70%.

  13. In order to reduce the ecological impact of manufacturing, it is necessary to minimize the environmental burden of each part of the system. We have developed a new computerized simulation method for assessing the environmental impact of proposed new products and manufacturing processes. Inputs to the simulator include environmental loads, and product and facility information. The materials and energy which are input to and output from the system under analysis are measured in "Ecounits", an index which represents the total environmental burden of the resources used and system outputs. The output from the simulator allows calculation of the predicted increment in ecounits caused by operation of the system. During tests of the simulator, the environmental impact of a hypothetical factory producing mechanical components was predicted, and the simulation method was shown to provide realistic and useful data.

  13. This research proposed a new combustion chamber to achieve the simultaneous reduction of NOx and smoke from diesel engines. This combustion chamber generates a strong disturbance in the middle and late stages of combustion that enhances the smoke oxidation. The initial combustion occurs in a fuelrich state in the prechamber and the middle and late stages of combustion occur in a lean state mostly in the main chamber; hence, NOx is reduced. The disturbancetends to shorten the combustion duration which compensates for the tendency of the lean combustion to prolong the combustion duration. Performance and emission characteristics of the test engines were examined, then the results were discussed with respect to rate of heat releasein the divided chambers and so on.

  13. In this research, a new combustion chamber was proposed to achieve the simultaneous reduction in NOx and smoke from diesel engines. This combustion chamber generates the strong disturbunce in the middle and late stage of combustion that enhances the smoke oxidation. For the reduction of NOx, the initial combustion occurs in fuelrich state in the auxiliary chamber and the middle and the late combustion occures in lean state mostly in the main chamber. The defect of lead combustion in the main chamber that prolongs the combustion duration is compensated by the effect of the flow disturbunce that shortens the combustion duration. According to this idea, the prototype engines were built, then their performance and emission characteristics were examined. Not all the results were completely desirable. However the potential for improving the emission characteristics was clarified.

  13. The aim of this project is to develop a catalytic technology for reducing aromatics content in diesel fuels.
    In this technology, aromatic compounds are hydrogenated or hydrocracked into non-aromatic compounds
    over the hydrotreating catalysts.We made two strategic approaches for aromatics reduction: (1) evaluation of catalytic reaction mechanisms in aromatic saturation and aromatic ring opening reactions to support
    optimization of the reaction conditions sa well as primary selection of the hydrotreating catalysts; (2) design of hydrotreating catalysts which are not only highly active and selective for aromatics reduction, but also highly tough for catalyst deactivation.

Photocatalysts based on titanium dioxide were found to remove ppm-level nitrogen and sulfur oxides from air by oxidation. As the catalysts require only near ultraviolet light for activation and water for regeneration by rinsing the oxidation products (nitrate and sulfate) off, the catalysts can be operated outdoor conditions with natural energies only. The reaction mechanisms, improvement of photocatalytic activity, and immobilization of the catalysts are studied in the project.

  13. The goal of this research is to elucidate mechanisms for plasma chemical decomposition of VOCs and clarify the effects of reaction parameters such as background gas, residence time, field strength, and input energy density on decomposition efficiencies and product distributions. The data obtained to date show that the initial steps for VOC decomposition proceed homolytically via energy transfer from hot electrons in nonthermal plasma media, independent of electron affinities of VOCs. VOC decomposition efficiencies increase with the magnitudes of field strength and input energy density. Active oxygen species partly promote initial VOC decomposition, but its contribution is much smaller than its nonoxidative decomposition. Product distributions are greatly affected by background gas and humidification. Better carbon recoveries and lower organic byproduct yields are obtained due to promoted autoxidation of intermediate radicals derived from VOC docomposition. Water promotes monooxygen transfer in plasma, accelerating alcohol formation from paraffins, epoxidation of olefins, and oxidation of CO to CO2D

It is especially required that the valency of these metals is determined because of the correlation of the harmfulness. In this research, the analytical method that can be highly sensitive to these metals simultaneously, and quantitatively analyze the valency of the metals is established.

It is inferred that current authorized method (JIS Z8808) for measuring source dust can not estimate substances emitted from stationary sources which might change to supended particulate matter (Ssuspendedhe ambient air. We call the substances, which are emitted from the sources as gaseous component, and immediately changed to particles in the air near the stack, as the condensed dust. This research aims to establish the simplified-automatic measuring method of concentration and chemical component on particle size of source dust including condensed dust.

  13. This study aims to develop a new method for the sequestering of CO2 in deep sea as CO2 hydrate. Under the temperature and pressure conditions of deep sea, the mixture of CO2 and water forms the crystalline molecular complex, called CO2 hydrate clathrate. CO2 molecules is enclosed within the lattice formed by water molecules, which are strongly hydrogen bonded with each other. As the density of CO2 hydrate is higher than that of sea water, CO2 hydrate would be sequestered in deep sea. To investigate the feasibility of deep sea CO2 sequestering, it is necessary to study the physical properties of CO2 hydrate. The object of this study are to investigate the formation and dissociation processes of CO2 hydrate and its physical properties.

  13. The objectives of this research project are to elucidate the mecha- nism of nitrogen and nitrous oxides (N2O and NOx) formation and to develop new combustion technology for simultaneous control of N2O and NOx emissions from bubbling and circulating fluidized-bed coal combus- tors. The effects of operating conditions, and coal and combustor typeson the emission levels of N2O and NOx have been examined using experi- mental combustors. In addition, catalytic effects of CaO, MgO and hematite particles were examined to reduce the emission levels. Finaly a novel technique for simultaneous reduction of the emissions, the ITS System, has been proposed based on the above experience. The ITS Systemenables us to reduce N2O and NOx emissions respectively by over 85% and 60% in the bubbling fluidized-bed combustor.

  13. In order to decompose and remove odor substances which are emitted in urban living area, this research project aims at the development of high-performance novel catalysts. Odor compounds such as ammonia and aminesare oxidatively decomposed over the catalysts at low temperatures and are converted to odorless and harmless compounds. Especially, special catalytic function will be developed with no evolution of carbon monoxide and nitrogen oxides which may cause another pollution. This catalyst can be applicable to the equipments for treating odor emitted from food or fertilizer plants, and also to indoor air purification for improving the living and working environments.

  13. The aim of this research is the development of novel catalytic technologies for the removal of NOx emitted from lean-burn gasoline and diesel engines. We have found that gold exhibits good catalytic performances for the reduction of NO with propene in the presence of excess oxygen and moisture when gold is supported on alumina and zinc with high dispersion. Especially, gold supported on alumina gave the highest conversion of NO to nitrogen as about 80% at 700K. The mechanical mixing of manganese oxide with Au/alumina appreciably increased the conversion of NO to nitrogen. It reached over 90% at temperatures between 623K and 723K. The roles of manganese oxide which was mixed with Au/alumina should be concluded that it promots the NO oxidation.

  13. The quick development in industry and economics in East Asia brings large amount of emission of air pollutants, for examples, sulfur and nitrogen dioxides, into the atmosphere, especially from coal burning power plants. Therefore, acid rain is very important environmental problem in East Asia region. In order to clarify and evaluate the effect of acid rain on the acidification of natural and urban environment, the multilateral cooperative research on development of an advanced acid rain monitoring system is carried. This cooperative research includes following contents; (1) study on development of sensors for measuring the primary components of acid rain, (2) fundamental study on development of automatic monitoring system for measuring the acid rain components, and (3) study on development of the prediction model for environmental influence of acid deposition,are carried out among universities and institutions in APEC members. ONRI is mainly engaged in the research on sensors.
