Butanediol from Raw Sugar (By-Products: THF & Ammonium Sulfate)

Report Abstract

This report concerns the bio-based BDO production in the Germany from raw sugar. In this report, BDO is produced using a two-step process similar to Myriant/JM Davy technology. In this process, raw sugar is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are fermented to produce to succinic acid, that is then hydrogenated to BDO. Ammonium sulfate and tetrahydrofuran (THF) are generated as by-products.

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

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