Cumene from Benzene and RG Propylene (Zeolite Catalyst)
Cumene Operating Costs & Plant Construction Costs
This feasibility study reviews Cumene production from benzene and refinery grade (RG) propylene via an alkylation process, which is carried out using a zeolite catalyst. The economic assessment assumes a plant located in the United States.
The report provides a comprehensive study of Cumene production and related Cumene production cost, covering three key aspects: a complete description of the Cumene production process examined; an in-depth analysis of the related Cumene plant capital cost (Capex); and an evaluation of the respective Cumene plant operating costs (Opex).
The Cumene production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Cumene plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Cumene plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises two major sections: (1) Reaction; and (2) Distillation.
Reaction. In the reaction section, there are two reactors - the alkylation reactor and the transalkylation reactor. Fresh refinery grade propylene and recycled benzene are mixed and fed to the alkylation reactor. The alkylation reactor effluent comprises in addition to the Cumene product, unreacted benzene, non-reactive propane (present in the propylene feed), side products polyisopropylebenzenes (PIPB) and heavy ends. The effluent is routed to the Depropanizer column in the distillation section. The transalkylation reactor, in turn, is fed with recycled benzene and PIPB recovered in the distillation section. In the transalkyation reaction, PIPBs are reacted with benzene to form Cumene. The transalkylation reactor effluent is routed to the Benzene Recovery column in the distillation section.
Distillation. In the distillation section, a depropanizer column removes non-reactive propane from the alkylation reactor effluent. The propane-free reaction effluent is routed to the Benzene Recovery column, while propane is purged from the process. The Benzene recovery column is also fed with fresh benzene and the product of the Transalkylation reactor. Benzene is separated and recycled to the reaction section, while a crude Cumene stream obtained from the bottom of the column is routed to the Cumene purification column, from which high-purity product is obtained. The impurities rejected in the Cumene column are treated in a further column, which recovers PIPB for the transalkylation reaction.
