Abstract
The design for the annual production capacity of 100,000 Ethylbenzene Dehydrogena- tion to Styrene process, technology used with a low activity, high selectivity of the iron oxide catalyst, in the light of Lummus (Lummus) styrene production technology to ethylbenzene from Styrene production of hydrogen.
Design elements include: process design, process calculation, equipment design.
Designed for use mainly by the dehydrogenation reaction and distillation systems composed of two processes. Dehydrogenation of ethylbenzene in adiabatic fixed-bed reactor, the reactant to the distillation process. First by ethylbenzene - tower isolated ethylbenzene styrene (benzene, toluene) and the crude styrene (with the reorganization of sub-and tar). Ethylbenzene benzene distillate delivery - Tap into toluene benzene, toluene ethylbenzene distillate and recovery, the recovery process of ethylbenzene dehydrogenation to return. Send crude distillation column is divided into fine styrene and styrene tar.
Computing technology, including the main reactor and distillation of the material balance and heat balance.
Equipment designed primarily ethylbenzene / styrene separation tower design, calculate the actual plate number 26, feed in the first 13 boards, tower diameter 1.80m, height 20m
