This report presents a cost analysis of 1,3-Propanediol (PDO) production from crude glycerol using a fermentation process. In this process, crude glycerol obtained as by-product of biodiesel plants, is used as the main raw material. This report was developed based essentially on the following reference(s): Keywords: Bio-PDO, Trimethylene Glycol, Polytrimethylene Terephthalate, PTT, Aerobic Fermentation, Tate and Lyle
This report presents a cost analysis of 1,3-Propanediol (PDO) production from glucose syrup using a fermentation process. The process examined is similar to DuPont process. In this process, a 70 wt% glucose-water syrup is used as raw material. This report was developed based essentially on the following reference(s): (1) US Patent 7745184, issued to DuPont and Genencor in 2010 (2) US Patent 6479716, issued to Archer-Daniels-Midland in 2002 Keywords: Bio-PDO, Trimethylene Glycol, Polytrimethylene Terephthalate, PTT, Aerobic Fermentation, Tate and Lyle
This report presents a cost analysis of 1,3-Propanediol (PDO) production from raw sugar using a fermentation process. The process examined is similar to DuPont process. In this process, raw sugar (sucrose) is diluted and sucrose is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are then fermented to produce Propanediol. This report was developed based essentially on the following reference(s): (1) US Patent 7745184, issued to DuPont and Genencor in 2010 (2) US Patent 6479716, issued to Archer-Daniels-Midland in 2002 Keywords: Bio-PDO, Trimethylene Glycol, Polytrimethylene Terephthalate, PTT, Aerobic Fermentation, Tate and Lyle
This report presents a cost analysis of Propanol production from glycerol. In this process, crude glycerol (80 wt% glycerol content) is used as feedstock. This report was developed based essentially on the following reference(s): Keywords: Glycerin, Propyl Alcohol, Biodiesel, Quattor, Petrobras
This report presents a cost analysis of Propylene Glycol production from glycerol using a liquid-phase process. The process examined is similar to Suppes process. In this process, technical grade glycerol (99.5 wt% glycerol content) is used as feedstock and ethylene glycol is generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Glycerin, Senergy Chemical, Propane-1,2-diol, Hydrogenolysis
This report presents a cost analysis of Propylene Glycol production from glycerol using a vapor-phase process. The process examined is similar to Davy Technologies process. In this process, technical grade glycerol (99.5 wt% glycerol content) is used as feedstock and ethylene glycol is generated as by-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) Keywords: Glycerin, Davy Process Technology, DPT, Propane-1,2-diol, Hydrogenolysis, Cargill, Ashland
This report presents a cost analysis of bio-based Isobutanol production from corn stover via a biochemical conversion process. This process involves the following steps in the production of cellulosic Isobutanol: corn stover pretreatment with dilute acid and ammonia conditioning; enzymatic hydrolysis; and fermentation. Electricity is also generated as by-product. This report was developed based essentially on the following reference(s): Keywords: Butyl Alcohol, Biofuel, Biobutanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose
This report presents a cost analysis of Technical Grade Glycerol production via fuel grade glycerol treatment. The process examined is a typical pre-treatment process. This report was developed based essentially on the following reference(s): Keywords: Glycerin, Industrial Grade Glycerol, Lurgi
