Abstract

산업용 폴리스틸렌 괴상중합공정에서의 반응기 모델에 관한 연구를 수행하였다. 산업용 연속 중합 반응기는 전단계 중합 반응기(CSTR), 수평의 여러 반응실로 되어 있는 주반응기 및 높은 점도의 고분자 유체를 이동하기 위한 관형반응기로 구성되어 있다. 본 연구에서 여러 반응실의 주반응기는 다단계 CSTR로 생각하였다. 산업용 연속 반응기 모델이 제시되었고, 현장 데이터와 비교하였다. 현장 데이터는 중합 속도와 고분자의 분자량에서 모델과 아주 만족스럽게 일치되었다. 제안된 반응기 모델은 높은 분자량을 가지는 고분자를 생산하기 위한 중합공정 조건을 찾을 수 있음을 보여 주고 있다.

Modeling of a reactor for bulk styrene polymerization in industrial manufacturing processes has been studied. The continuous industrial reactor system was composed of three reactor units; a prepolymerization reactor(e.g. stirred tank reactors), a main reactor with horizontal multicompartmented reactors and a tubular reactor for transportation of the viscous polymerizing liquid. In this study, the multicompartmented reactor was assumed to be cascade of CSTRs. The industrial continuous reactor model was presented and its performance was compared with industrial data. The industrial data indicated that the model was quite satisfactory in describing the polymerization rate and polymer molecular weights. It was shown that the proposed reactor model could be used to find the polymerization process conditions to produce high molecular weight polymers.
