Disproportionation and paraxylene plant optimization project
The disproportionation and paraxylene devices are used as upstream and downstream mutual feeding devices.In order to realize the independence and strong operability of the two devices,independent aromatic component separation processes and equipment are generally provided.This paper discusses the design optimization and separation method of disproportionation and paraxylene unit as a combined unit.According to the precise calculation and design,the industrial application is realized,and the feasible suggestions are put forward.
