Lactic Acid Production From Raw Sugar Cost Analysis La E23b PDF Download

This report presents a cost analysis of Lactic Acid production from glucose syrup using a fermentation process. The process examined is similar to Corbion process. In this process, a 70 wt% glucose-water syrup is used as raw material. The fermentation broth is acidified in order to recover Lactic Acid and the product purification is realized by the use of a solvent. An 88 wt% Lactic Acid solution in water is generated as final product. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): (1) US Patent 7867736, issued to Purac (now Corbion) in 2011; (2) US Patent 6747173, issued to Purac (now Corbion) in 2004 Keywords: Dextrose, 2-Hydroxypropanoic Acid, Anaerobic Fermentation, Calcium Carbonate, Sulfuric Acid
