Rotary kiln in cement work has been evaluated for a wide variety of organic wastes such as wood, used tyres, plastic wastes and automobile shredder residue (ASR). However the presence of chlorine hampers the use of ASR as fuel in rotary kiln. Therefore, the behavior characteristics of chlorine components in rotary kiln should be considered to develop an effective method for ASR treatment to recovery energy resources. The aim of this paper is to present the chlorine control system applied to a cement manufacturing process for ASR use as an alternative fuel. In this work, the simulation of bypass unit and cyclones for chlorine control in rotary kiln has been studied and compared with the operation results of field test.

ELVs (End-of-Vehicles) in Korea incrasease continusely because of increase of used car. Automobile Shredder Residue (ASR) is final product of ELVs (End-of-Vehicles) after recycling. Automobile Shredder Residue are composed of light and heavy fluffs and soil/dust. In this study, 5 ton/day pilot plant of shaft type has been designed and constructed and 15 times of test run were performed. For the stable operation, operation conditions such as the amount of fed ASR and cokes, air flow and temperature in the gasification melting system have been changed and the composition of the produced gas such as $H_2$, CO and $CH_4$ and air pollution compound including dioxin discharged from the stack have been analyzed.

Until tile 1980s, the disposal of End of Life Vehicles (ELV) was considered unproblematic in Japan, Korea. and Taiwan. But in recent years, as environmental problems have attracted increasing attention. the processing oi ELV has become one of the most critical environmental issues. Discarded ELV represent a serious source of waste generation and pollution. In this paper, I will analyze the ELV problem from three view points: 1) ELV abandoned in the environment; 2) Significant environmental hazards caused by dismantling operations; and 3) Problems of how to deal with Automobile Shredder Residue (ASR).

폐차잔재물중 가연성 성분을 시멘트 제조공정의 열원으로 활용하기 위한 연구가 현재 활발히 진행 중에 있다. 그러나 이러한 폐차잔재물을 시멘트 제조공정의 보조열원으로 사용하기 위해서는 에너지활용에 대한 경제성 및 환경기준과 더불어 시멘트 제조공정의 안정적 조업조건에 대한 검토가 이뤄져야만 하며 특히 폐차잔재물의 연소시 시멘트 제조공정에서의 염소물질의 거동특성에 대한 연구가 반드시 선행되어야만 한다. 따라서 본 연구에서는 이러한 폐차잔재물의 시멘트 제조공정에 대한 열원활용의 최적조건을 도출하고자 현장적용 전 킬른내 염소성분의 제어를 위한 Bypass unit의 Cyclone에 대한 전산모사연구를 수행하였으며 이러한 전산모사결과를 바탕으로 실제 시멘트 제조공정에 대한 폐차잔재물의 현장적용 실험을 수행하였다. 또한 본 연구로부터 시멘트 제조공정에 대한 폐차잔재물의 열원활용 가능성을 확인할 수 있었으며 폐차잔재물의 투입시 시멘트 제조공정의 안정적 조업조건을 확보할 수 있었다.

On July 5,2002 the Law Concerning Recycling of End-of Life Vehicles popularly known as the "Automobile Recycling Law" was enacted in Japan. This paper examines the features of this Law, reasons why the Law was brought into existence, and its predicted impacts on the automobile industry. Pursuant to the Law, the current automobile recycling system was replaced by a new one in January 1, 2005.

Automobile shredder residue (ASR) is the final waste produced when end-of-life vehicles (ELVs) are shredded. ASR can be separated using mineral-processing operations such as comminution, air classification, magnetic separation, and/or electrostatic separation. In this work, trajectory analyses of conductors (copper) and non-conductors (glass) in the ASR have been carried out using induction electrostatic separator for predicting or improving the ASR-separation efficiency. From results of trajectory analysis for conductors, the trajectories of copper wire by observation versus simulation for coarse particles of 0.5 and 0.25 mm showed consistent congruity. The observed 0.06 mm fine-particles trajectory was deflected toward the (-) attractive electrode owing to the charge-density effects due to the particle characteristics and relative humidity. In the case of non-conductors, the actual trajectory of dielectric glass deflected toward the (-) electrode, showing characteristics similar to those of conductive particles. The analyses of stereoscopic microscope and SEM & EDS found heterologous materials (fine ferrous particles and conductive organics) on the glass surface. This demonstrates the glass decreasing separation efficiency for non-ferrous metals during electrostatic separation for the recycling of ASR. Future work will require a pretreatment process for eliminating impurities from the glass and advanced trajectory-simulation processes.

In the last year, the number of registered vehicles in Korea surpassed the 15 million mark, and increase in number continuously. Nowdays, this tendency has raised some problems inevitably in the view of expansion of ELV(End of Life Vehicles) and earth environment pollution resulted from it. A foreign country is strengthening law about a car recycling for to solve this problem. Car recycling technology in Japan was introduced in this paper.

폐차잔재를 시멘트제조공정의 열원으로 활용하기 위해서는 연료로 사용하기 위한 경제성과 더불어 시멘트제조공정 및 품질 그리고 환경기준을 만족해야 한다. 따라서 폐차잔재의 최적투입방법과 폐차잔재의 연소시 염소물질의 거동특성에 대한 연구가 선행되어야만 한다. 본 연구에서는 이러한 폐차잔재의 시멘트 킬른 현장적용에 따른 위험요소와 시행착오를 최소화하기 위하여 최적 연료화 조건에 대한 전산모사 연구를 하였으며 전산모사의 대상공정으로는 폐차잔재가 투입될 Precalciner와 염소제어를 위하여 Bypass unit가 설치될 Precalciner의 하단부 그리고 Cyclone을 선정하여 입자 및 가스상의 거동 특성을 고찰하였다. 본 연구로부터 폐차잔재의 투입위치로는 현재의 석탄 투입위치를 활용하는 것이 효과적일 것으로 판단되었으며 Precalciner의 하단부에 대한 가스상 및 입자상의 거동특성을 활용하여 Bypass unit를 설치할 최적의 위치를 선정할 수 있었다. 또한 Cyclone의 입자 거동특성 결과로부터 염소 제어를 위한 각 Cyclone의 입자회수율에 대한 정보 및 공정의 개선 가능성을 확인할 수 있었다.

Automobile Shredder Residue (ASR) is very appropriate in a gasification melting system. Gasification melting system, because of high reaction temperature over than $1,350^{\circ}C$, can reduce harmful materials. To use the gasification processes for hydrogen production, the high concentration of CO in syngas must be converted into hydrogen gas by using water gas shift reaction. In this study, the characteristics of shift reaction of the high temperature catalyst (KATALCO 71-5M) and the low temperature catalyst (KATALCO 83-3X) in the fixed - bed reactor has been determined by using simulation gas which is equal with the syngas composition of gasification melting process. The carbon monoxide composition has been decreased as the WGS reaction temperature has increased. And the occurrence quantity of the hydrogen and the carbon dioxide increased. When using the high temperature catalyst, the carbon monoxide conversion ratio ($1-CO_{out}/CO_{in}$) rose up to 95.8 from 55.6. Compared with average conversion ratio from the identical synthesis gas composition, the low temperature catalyst was better than the high temperature catalyst.
