Butanediol Production from Succinic Acid
Butanediol Operating Costs & Plant Construction Costs
This feasibility study examines 1,4-Butanediol (BDO) production from succinic acid in the United States using a hydrogenation process similar to the one proposed by BioAmber.
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.

The process under analysis comprises two major sections: (1) Hydrogenation Reaction; and (2) Purification.
Hydrogenation Reaction. A solution of bio-succinic acid in water is pre-heated and sent to the hydrogenation reactor. Hydrogen is compressed and fed in excess to the reactor. The hydrogenation reaction occurs in aqueous medium in a fixed-bed reactor. The process uses a bimetallic catalyst consisting of metals (like ruthenium, rhenium, tin and others) on carbon support. The exothermic reaction product is mostly 1,4-butanediol (selectivity to BDO of about 90%). Side products include tetrahydrofuran (THF), gamma-butyrolactone (GBL), and linear alcohols (n-butanol, n-propanol). The bio-succinic acid is totally reacted, and the non-reacted hydrogen is compressed and recycled back to the reactor. The product stream is cooled and sent to flash vessels to recover non-reacted hydrogen and eliminate volatiles.
Purification. The product from the flash vessels is sent to a series of distillation columns to separate BDO from side products. In the first column, BDO, GBL and water are removed from bottoms and then sent to the drying column, where most of the water is removed. The column’s top is sent to lights column, to recover by-products as fuel. The water recovered is sent to a tank for further disposal. The stream from drying column’s bottoms is sent to a BDO recovery column and further to a heavies column, where a stream of 99.5 wt.% BDO is finally achieved.
