Abstract

본 발명은 비닐 클로라이드 수지(PVC)의 제조에 있어서의 잔류 단량체의 제거방법 및 제거용 타워를 제공한다. 잔류단량체를, 슬러리를 중합시킨 후에 PVC 슬러리로부터 증기와 접촉시켜 제거할 경우, 슬러리중에 생성된 발포체를 안정한 유동상태로 유지되도록 조절한다. 잔류 단량체는 효과적으로 제거되고 외부 물질은 포함되지 않는다. 타워는 2가지 이상의 형상을 가지며 상부 및 하부로 나뉜다. 상부의 내경은 하부의 내경보다 크다. 각각의 영역에는 하나 이상의 천공 트레이가 제공된다. 또한 하나 이상의 온수 방출장치가 타워에 제공된다.

Description
