本次设计为苯乙烯生产中年处理3.6万吨苯乙烯-乙苯分离装置的设计.
我国苯乙烯生产通常采用负压绝热脱氢法,装置由乙苯脱氢和脱氢混合液精馏两部分组成.脱氢混合液的主要组成为苯、甲苯、乙苯、苯乙烯和焦油等.其中乙苯(EB)与苯乙烯的分离是精馏的最关键技术.本文就是采用精馏的技术.
本文对苯乙烯-乙苯分离装置的物料衡算,热量衡算,还有精馏塔的塔体工艺尺寸的计算还有附属设备换热器、储罐、管径、泵的计算进行了计算.

The design for the production of styrene middle-aged processing 36000 tons of styrene ethylbenzene separation device design.
China's styrene production usually adopts the negative pressure adiabatic dehydrogenation method, device by dehydrogenation of ethylbenzene dehydrogenation mixture distillation and composed of two parts. Dehydrogenated mixture mainly consists of benzene, toluene, ethylbenzene, styrene and tar. The ethyl benzene (EB) and styrene distillation separation is the most key technologies. This paper is the use of distillation technology.
In this paper, styrene and ethylbenzene separation device for material balance, heat balance, and the rectifying tower body technological dimension calculation and ancillary equipment heat exchanger, tank, pipe diameter, pump calculation were calculated.
