Isobutylene from Isobutane (Steam Reforming and Oxyreaction)
Isobutylene Operating Costs & Plant Construction Costs
This report analyses the economics of Isobutylene production from isobutane in the USA. The process examined is a dehydrogenation process similar to Uhde STAR. Initially, isobutane undergoes steam reforming, which is followed by oxyreaction, yielding isobutylene.
The report provides a comprehensive study of Isobutylene production and related Isobutylene production cost, covering three key aspects: a complete description of the Isobutylene production process examined; an in-depth analysis of the related Isobutylene plant capital cost (Capex); and an evaluation of the respective Isobutylene plant operating costs (Opex).
The Isobutylene 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 Isobutylene 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 Isobutylene plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

Product
Isobutylene. Isobutylene (also known as Isobutene) is one of the butylene isomers, used as an intermediate in the production of MTBE, ETBE, isooctane, and methacrolein. Polymerization of Isobutylene produces butyl rubber. Most of times, C4 isomers are produced commercially as by-products from petroleum refinery/petrochemical processes. Isobutylene, specifically, can be produced on commercial scale from processes based on the dehydration of tert-butyl alcohol and on the catalytic dehydrogenation of isobutane.
Raw Material
Isobutane. Isobutane, also known as methylpropane, is a chemical compound mainly used as refrigerant. Presenting a very low Global Warming Potential (having a value of 3.3 times the GWP of carbon dioxide), isobutane has in fact replaced chlorofluorocarbon or hydrofluorocarbon refrigerants in air conditioning systems. Manufacturing of isobutane may rely on isomerization of n-butane or in the separation of a mixed C4 hydrocarbons stream generated in naphtha crackers.
