Isobutane Production

Report Abstract

This report examines the costs incurring from producing Isobutane via catalytic isomerization of n-butane. n-Butane is dehydrogenated to 1-butene, which is then rearranged to isobutylene. Finally, isobutylene is hydrogenated producing isobutane. The economic analysis provided assumes a plant located in the United States.

The report provides a comprehensive study of Isobutane production and related Isobutane production cost, covering three key aspects: a complete description of the Isobutane production process examined; an in-depth analysis of the related Isobutane plant capital cost (Capex); and an evaluation of the respective Isobutane plant operating costs (Opex).

The Isobutane 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 Isobutane 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 Isobutane plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
