碩士 === 國立臺灣科技大學 === 化學工程系 === 90 === A mathematical kinetic EVA model is developed to simulate the behavior of multizone, multifeed high-pressure EVA polymerization autoclave reactor. Dynamic mass and energy balance are derived to predict the polymerization rate, monomer concentration, molecular weight(Mw…etc.), and temperature profile with respect to the position in the reactor. The effects of grade transition on the EVA autoclave reactor model are investigated. It is shown that the proposed model is capable of predicting the behavior of EVA autoclaves and can be used for the process design, operating condition optimization, control strategy, and grade transition study of the EVA autoclave reactor.
