METHOD OF SEGREGATING ETHYL BENZENE AND STYRENE BY DESTILLATION OF LIQUID MIXTURE CONTAINING MAINLY STYRENE AND ETHYL BENZENE

摘要

A process for separating ethylbenzene and styrene by distillation is described. The process provides the advantages of a vapor compression/heat pump system, and is designed in such a manner that the energy applied is optimally utilized. The head pressure of the distillation column (1) is controlled in a simple manner, whereby a surprisingly stable column is achieved.
