Isoprene Production from Isobutylene

This report presents the economics of Isoprene production from isobutylene and formaldehyde. The process examined is a typical two-step process. In this process, isobutylene contained in a C4 cut stream is the main raw material used. First, the isobutylene is reacted with formaldehyde forming 4,4-dimethyl-1,3-metadioxane (DMD) as intermediate. This intermediate is then cracked in the vapor phase, producing Isoprene.

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

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