An alkylation system converts benzene and propylene to cumene. A small fraction of the cumene is further alkylated to polyisopropylbenzenes (PIPB). The alkylation reaction is exothermic and the alkylation reaction system is staged with intermediate cooling to control the reaction temperature.
A single bed transalkylation system converts PIPB with benzene to additional cumene. Transalkylation is isothermal.
A distillation train recycles excess benzene to reactors, isolates cumene as product, and recovers PIPB for transalkylation.
The Badger Cumene process is a high yield, high energy efficiency, low environmental impact process that is easy to operate and maintain, allowing for very low production cost.
