Abstract
본 연구에서는 휘발성 유기화합물 중 산업공정에서 사용빈도가 가장 높은 방향족류의 toluene, 케톤류의 MEK, 알코올류의 IPA에 의한 삼성분계 휘발성 유기화합물의 탄소계 흡착제에 대한 흡착특성 실험을 수행하였다. 입상 활성탄, 활성 탄소섬유를 이용한 단일흡착제와 입상 활성탄과 활성탄소섬유를 동시에 적용한 조합흡착제를 사용하여 흡착성능과 흡착량을 비교 분석하였다. 실험용 흡착장치를 사용하여 단일성분 및 삼성분계 휘발성 유기화합물에 대한 흡착파과 실험을 수행하였으며, 각 경우에 대해 흡착량과 흡착성능을 비교하였다. 입상 활성탄은 toluene의 단일흡착 시 높은 흡착성능을 보였으나, IPA, MEK의 단일성분과 삼성분계 흡착실험에서는 상대적으로 낮은 성능을 보였다. 활성탄소섬유와 조합흡착제는 단일성분 흡착결과에서 모두 우수한 흡착성능을 보였으나, 삼성분계 흡착의 경우에는 흡착제의 경제성과 흡착효율을 고려하였을 때 입상 활성탄과 활성탄소섬유를 동시에 적용한 조합흡착제가 흡착제로서 가장 적합함을 확인할 수 있었다.
Toluene of aromatic compounds, MEK of ketones and IPA of alcohols were extremely used as VOCs (Volatile Organic Compounds) on the getting into step with industrial process. The adsorption characteristics of three component solvent vapors (Toluene-MEK-IPA) on the activated carbonaceous adsorbents such as AC, ACF and AC+ACF were investigated in a stainless steel fixed bed adsorption experimental apparatus 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 carbon and activated carbon fiber. The breakthrough curves and adsorption capacity have been obtained at atmospheric pressure in a adsorption fixed bed. It has been found that non-polar and larger molecules have been adsorbed better than polar and smaller molecules. Especially, alcohols and ketones were poorly adsorbed due to competitive adsorbability in ternary mixture system. However, it could be overcome by employment of activated carbonaceous adsorbent which have different porosity distribution appropriately.
