Design and Analysis of Process Flow of Synthesis Section of Styrene Chemical Plant
In this paper,styrene was prepared by catalytic dehydrogenation of ethylbenzene from benzene alkylation.The process flow of ethylbenzene production device is mainly divided into two stages of alkylation and rectification,and the process flow of styrene typical device is mainly divided into two sections of dehydrogenation and rectification.The styrene distillation unit in this paper adopts the sequential separation process,that is,the crude styrene liquid is first passed through the benzene and toluene column,and the light components such as benzene and toluene are separated from ethylbenzene and styrene.According to the relevant design requirements,scientific process design and equipment selection of the entire production section are carried out.
