Ethyl benzene (EB) is an aromatic hydrocarbon important in petrochemical industry today mainly as intermediate in the production of styrene. The production of ethylbenzene involves the alkylation of benzene with ethylene either through liquid phase or vapour phase processes. The process however provides some challenges due to the production of byproduct di-ethylbenzene (DEB) in one of the side reaction due to the reaction of EB with ethylene. This study discusses some interesting features in the process using two reactors, two separation columns and two recycle stream. Simulation of this EB process in Aspen HYSYS is conducted to study the possibility of recycling DEB byproduct to extinction, the effects of size of reactor and temperature used on the selectivity and others. The viability of including recycle streams to recycle benzene and DEB back into the system is also discussed.
