High-temperature sensible heat recovery technology for effluent from ethylbenzene dehydrogenation unit
Changxi Miao · Xiandai huagong · 2008
A detailed analysis is conducted of that traditional heat recovery processes for high-temperature effluent from ethylbenzene(EB) dehydrogenation unit,and a three-stage L-type complex heat exchanger is employed for effluent’s sensible heat recovery from high-temperature reactor.the operational stability for heat exchanger is improved by avoiding the fracture of section tube of the No.1 exchanger,and the new process is successfully applied in an EB dehydrogenation unit with production capacity of 80kt/a of styrene.
