Succinic acid biorefineries

Introduction

The blog will open soon a new section focused on summarizing the information available about the commercial and pilot plants of the most promising Biobased Chemical Building Blocks (BCBB). The section will contain links to monographic posts updated in a regular basis. I have chosen bio-succinic acid to start the series because some companies have achieved important milestones related to its large-scale commercialization. Clearly, it is one of the DoE´s top 12 BCBB that it is fulfilling the previous generated expectations.

Description 1,2,3

Succinic acid (butanedioic acid), is a diprotic, dicarboxylic acid with chemical formula C4H6O4. It is a water-soluble, colorless crystal with an acid taste. The name derives from Latin “succinum”, meaning amber, from which the acid was originally obtained by pulverising and distilling it using a sand bath. It is produced naturally as a product of cellular metabolism. In the chemical industry, it also plays an important role, being a key intermediate component for various products and processes.

Process technologies 2

Succinic acid is produced by several methods. Common industrial routes include hydrogenation of maleic acid, oxidation of 1,4-butanediol, and carbonylation of ethylene glycol. More recently, succinic acid has been produced through the fermentation of glucose from renewable feedstock and purification of raw biobased succinic acid. The tools used for this route of manufacturing succinic acid are bacteria or yeasts in a bioreactor known as a fermenter.

Applications 2,4,5,6

Viewed chemically, the biobased compound is absolutely identical with the product manufactured conventionally, so it has the same properties and applications. There is a multitude of potential uses for succinic acid:
  • Polybutylene Succinate (PBS) production. It is one of the newest biopolymers under development for numerous applications worldwide (mulch films, disposable cups, plastic bags,...).
  • Plasticizers production for PVC manufacture. It can also be used to meet the growing demand for plasticizers for biobased plastics.
  • Replace petrochemical-based adipic acid in the production of polyester polyols for polyurethanes (adhesives, coatings, sealants, shoe soles, flexible and rigid foams,…).
  • 1,4-Butanediol (BDO) production to obtain tetrahydrofuran (elastane fibers) and polybutylene terephthalate (electrical equipment, wheel covers, gearshift knobs,…).
  • Di-methyl Succinate (DMS) production. It is a biobased solvent, miscible with alcohols, ethers, ketones and most hydrocarbons. It is used as a coalescing agent for emulsion paints in low VOC coating applications.
