Abstract

실제 공정에서 사용빈도가 높은 비흡착성 화합물을 포함하고 있는 다성분계 가스상 휘발성유기화합물의 제거 및 회수의 최적설계 도출을 위하여 직경 10.2 cm × 높이 50 cm의 고정층 흡착탑에서 다성분계 휘발성유기화합물(toluenexylene-MEK, toluene-MEK-IPA)의 탄소흡착제에 대한 흡착실험을 수행하였다. 탄소흡착제로는 펠렛형 입상활성탄과 활성탄소섬유를 사용하였으며, 흡착실험을 통하여 흡착파과곡선을 구할 수 있었으며 이로부터 흡착제별 흡착특성을 고찰하였다. 흡착제별 흡착성능은 활성탄소섬유, 활성탄소섬유 +활성탄 조합흡착제, 활성탄 +활성탄 조합흡착제, 단독 활성탄 순으로 나타났으며, 탄소흡착제에 대한 휘발성유기화합물의 흡착은 분자량이 크고 비극성인 화합물이 저분자량이면서 극성의 정도가 강한 화합물에 비하여 흡착성능이 우수하였다. 특히, 다성분계 휘발성유기화합물의 흡착에서 알콜류 및 케톤류의 화합물은 흡착성능이 우수한 방향족류 흡착질의 경쟁흡착으로부터 밀리어 저조한 흡착성능을 나타내었으나, 기공들의 크기분포가 다른 탄소흡착제의 적절한 조합으로부터 현장 적용이 가능할 정도로 비흡착성 화합물의 배출문제를 억제할 수 있었다.

The adsorption characteristics of multi-component solvent vapors including poorly-adsorbable chemicals such as toluene-xylene-MEK and toluene-MEK-IPA on the activated carbonaceous adsorbents were investigated in a stainless steel fixed bed of 10.2 cm ID and 50 cm in height in order to identify those carbons for eliminating and recovering solvent vapors from industrial emission sources. The used activated carbonaceous adsorbents were pelletized commercial activated carbons and activated carbon fiber. Breakthrough curves and adsorption capacity at atmospheric pressures were obtained. It has been found that non-polar and larger molecules have been adsorbed better than polar and smaller molecules. In special, alcohols and ketones were poorly adsorbed caused by competitive adsorbability in multicomponent mixture system. However, it could be overcome by profitable employment of organization of cooperative system which was composed of different porosity activated carbonaceous adsorbents appropriately.
