Book Description
This report presents a cost analysis of Hydrous Ethanol production from corn. The process examined is a typical dry milling process. In the process examined, corn is ground, slurried with water and then submitted to enzymatic hydrolysis, which convert starch to glucose. Next, the glucose is fermented to Ethanol by yeasts, and the fermentation product is fed to a distillation system, yielding Hydrous Ethanol. The non-fermented material recovered is passed through centrifugation, evaporation and drying steps to produce Distiller's Dried Grain with Solubles (DDGS) as by-product. This report was developed based essentially on the following reference(s): (1) "Ethanol," Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) "Ethanol Processing," Occupational Safety and Health Administration (OSHA), Instruction TED 01-00-015 Keywords: Ethyl Alcohol, Bioethanol, Biomass, DDG, Dry Mill, Shelled Corn

Book Description
This report presents a cost analysis of Polylactic Acid (PLA) production starting from corn The first section of the examined process is similar to Cargill process for lactic acid production, while the second section is similar to the NatureWorks process for polymerization of lactic acid. In this process, shelled corn is passed through a wet milling process to form corn starch, which, in turn, is hydrolyzed to dextrose, the feed for the fermentation process that generates lactic acid . Lactic Acid recovery from the fermentation broth is carried out via trialkylamine solvent extraction in the presence of carbon dioxide. A L-Lactic Acid solution in water is formed and further polymerized to form Polylactic Acid. The conversion of corn into dextrose forms some residues that are sold as by-product. This report was developed based essentially on the following reference(s): (1) US Patent 6472559, issued to Cargill in 2002 (2) US Patent 8674056, issued to NatureWorks in 2014 (3) EP Patent 1247808, issued to Cargill in 2003 Keywords: Corn, Corn Starch, 2-Hydroxypropanoic Acid, Anaerobic Fermentation, Trialkyl Amine, Sodium Carbonate, Lactide, 2-Hydroxypropanoic Acid, Dow, Biodegradable Polymer

Book Description
This report presents a cost analysis of hydrous Ethanol production from corn. The process examined is a typical dry milling process. In this process, Distiller's Dried Grain with Solubles (DDGS) 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) This report was developed based essentially on the following reference(s): "Ethanol", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethyl Alcohol, Bioethanol, Biomass

Book Description
This book covers all facets involving the production and use of ethanol. Topics include the optimization of raw materials, energy, capital, process model-based computer control, and human resources to produce ethanol. It compares and contrasts processes to prepare ethanol using biotechnology processes to prepare ethanol from chemical synthesis. Matters of optimization of ethanol use as fuel/fuel components are addressed based on thermodynamics, kinetics, and usage. It also discusses pollutants produced from ethanol and mixtures containing ethanol, the status of ways to control these pollutants, and what can be done to minimize the harm to the earth’s ecosystems due to ethanol and gasoline reactions.
