Abstract

This study investigated the environmental effects of improving the general-type activated carbon adsorption tower used at the Sihwa/Banwol Industrial Complex with use of a cartridge-type activated carbon adsorption tower for the application of an activated carbon co-regenerated system. Four general-type activated carbon adsorption towers and two cartridge-type activated carbon adsorption towers were selected to analyze the properties of activated carbon and to compare the efficiency of reducing environmental pollutants. The results showed that the activated carbon used in the cartridge-type activated carbon adsorption towers was high quality activated carbon with an iodine adsorption force of more than 800 mg/g and that a good adsorption performance was maintained within the replacement cycle. From an analysis of the environmental pollutant reduction efficiency, it was confirmed that the cartridge-type activated carbon adsorption tower functioned properly as a prevention facility for handling emissions pollutants with a treatment efficiency of total hydrocarbons (THC), toluene, and methylethylketone (MEK) components of 71%, 77%, and 80%, respectively. The general activated carbon adsorption tower, which was confirmed to use low-performance activated carbon, had a very low treatment efficiency and did not function properly as a prevention facility for dealing with emission pollutants. It is believed that it is possible to reduce pollutants during operations by changing from the general-type activated carbon adsorption tower to a cartridge-type activated carbon adsorption tower.

본 연구에서는 시화반월산업단지에서 보편적으로 사용하고 있는 일반형 활성탄흡착탑과 활성탄 공동재생시스템 적용을 위해 개발된 카트리지형 활성탄흡착탑으로 개선하여 얻게 되는 환경적 효과분석을 고찰하였다. 일반형 활성탄흡착탑 4개소와 카트리지형 활성탄흡착탑 2개소를 선정하여 사용하고 있는 활성탄의 물성특성을 분석하고 환경오염물질의 저감효율을 비교 분석하였다. 그 결과, 카트리지형 활성탄 흡착탑에 사용되는 활성탄은 요오드흡착력 800 mg g-1 이상의 양질의 활성탄으로 확인되었으며 교체주기내에서 양호한 수준으로 활성탄 흡착성능이 유지되는 것으로 확인되었다. 환경오염물질 저검효율 분석결과 카트리지형 활성탄 흡착탑의 경우 THC (Total Hydrocarbon), toluene 및 MEK (Methylethylketone) 성분의 처리효율이 각각 71%, 77% 및 80%로 좋은 처리효율을 보인 것으로 확인되었다. 일반형 활성탄 흡착탑은 처리효율이 매우 낮아 배출오염물질을 처리하는 방지시설로서의 역할을 제대로 하지 못하고 있었다. 일반형 활성탄 흡착탑을 카트리지형 활성탄 흡착탑으로 개선하여 운영 시 배출오염물질을 저감시킬 수 있을 것으로 판단된다.
