Lactic Acid Production from Glucose - Cost Analysis - LA E13A

Book excerpt: This report presents a cost analysis of Lactic Acid production from glucose syrup using a fermentation process The process examined is similar to Cargill process. In this process, a 70 wt% glucose-water syrup is used as raw material. Lactic Acid recovery from the fermentation broth is realized by trialkylamine solvent extraction in the presence of carbon dioxide. The final product is Food Grade Lactic Acid solution containing 88 wt% of Lactic Acid. This report was developed based essentially on the following reference(s): (1) US Patent 6472559, issued to Cargill in 2002 (2) "Hydrocarboxylic Acids", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Dextrose, 2-Hydroxypropanoic Acid, Anaerobic Fermentation, Trialkyl Amine, Sodium Carbonate
