Abstract

본 발명은, 수분 및 휘발성유기물을 함유하는 오프가스로부터 휘발성유기물을 회수하는 방법을 제공하는 것을 목적으로 하며, 그 구성에 있어서, 유기물 및 수분을 함유하는 가스로부터, 수분을 선택적으로 흡착하는 흡습제(4)를 충전한 탈습탑(5)에 의해 수분을 제거한 후, 상대적 저온조건하에서 유기물을 흡착제거하고, 유기물로 포화된 흡착탑(9)으로부터 상대적 고온조건에서 유기물을 이탈시키고, 이탈한 유기물은 저온 및/또는 기압조건하에서 액화해서 회수한다. 유기물이 제거되고, 무해화된 건조가스(11)는, 필요에 따라 가온한 후, 수분으로 포화한 탈습탑(5)으로 향류해서 퍼지해서 흡습제(4)의 재생을 행하고, 탈리한 수분과 함께 계외로 방출하는 것을 특징으로 한 것이다. 이로써, 유기물 및 흡착제의 열악화를 발생하는 일없이, 높은 농축배율로 유기물을 회수할 수 있는 효과를 얻게된다.
