Design of Styrene Production Plant Essay Sample. Low reactor temperatures suppress side reactions but require higher EB recycle to achieve the same styrene production rate, which increases separation costs. The main design optimization variables in this process are the steam-to-EB ratio, reactor inlet temperature, EB recycle flow rate and reactor size. <]>>
