Claims (8)

  1. 흡착오일에 의해 흡착된 방향족 탄화수소 회수와 방향족 탄화수소의 0.2%(부피) 이하의 양을 포함하는 잔류 유리방향족 탄화수소를 얻고, 방출가스에 존재하는 방향족 탄화수소 흡착을 위해 최소한 400℉의 온도에서 5%(부피) 증류한 방향족에 대해서 흡착 오일과 온도 35℉ 내지 125℉ 압력 15 내지 100psia에서 방출가스와 접촉하여 방향족 탄화수소 0.5% 내지 10%를 함유하는 방출가스를 최종처리하여, 수소 및 방향족 탄화수소를 함유하는 방출가스, 에틸벤젠으로부터 스티렌을 제조하는 공정에서 발생되는 방출가스를 처리하는 공정.
  2. 최종처리전에 방출가스의 방향족 탄화수소의 함량을 감소시키기 위해 방출가스를 에틸벤젠과 함께 스크럽하는 청구범위 제1항의 공정.
  3. 최종처리전에 방출가스를 액화하여 방향족 화합물을 흡수하기 위해 냉각하는 청구범위 제1항의 공정.
  4. 최종 처리전에 방출가스를 방향족화합물 함량을 감소시키기 위해 냉각하고 에틸벤젠으로 스크럽하는 청구범위 제1항의 공정.
  5. 흡착오일이 1000℉ 이하의 95%(부피) 증류온도를 갖는 청구범위 제1항의 공정.
  6. 흡착오일이 600℉ 이상의 5%(부피) 증류온도를 갖는 청구범위 제5항의 공정.
  7. 흡착오일이 폴리에틸벤젠과 디페닐에탄으로 된 에틸벤젠의 생성물로 부터의 중부산물인 청구범위 제6항의 공정.
  8. 방향족 탄화수소가 스트리핑에 의해 흡착으로부터 회수되는 청구범위 제1항에 따른 공정.
