This study is an economic analysis of the Quick-Germ technology when adapted to a medium sized (32.8 million gallons per year) dry-grind ethanol facility. Quick-Germ combines wet-mill steeping for germ separation for corn oil production in the dry-grind ethanol process in order to lower net feedstock costs. Previously published economic analysis budgets of a dry-grind ethanol facility and a proposed similarly adapted Quick-Germ adapted facility were used to create a model to determine the break-even production price of ethanol. Then, it was determined how much corn oil could be produced before the additional supply would lower the price enough to prevent market profitability. It was calculated that the Quick-Germ technology could potentially lower the break-even price of ethanol production by $0.054 per gallon. Also, approximately ten Quick-Germ converted dry-grind ethanol facilities producing approximately 197 million pounds of corn oil a year prevents additional profitable entry into the corn oil market.

It has been widely debated whether producing ethanol from corn is sustainable in the long term. Environmentally, the major concern is that producing ethanol from corn involves intensive water and energy consumption. Economically, recent fluctuations in petroleum, ethanol, and corn prices have driven several large producers of ethanol into bankruptcy. The ethanol industry is vulnerable to periods of economic weakness because its product value varies with oil prices but its raw material (corn) varies with food prices. To improve the economic sustainability of corn-to-ethanol production, several modified dry grind processes had been developed at the lab scale. The Quick-germ / Quick-fiber (QQ) process is one of them. However, there has been no analysis of the QQ process that provides detailed information related to the energy, water, and economic performance at a commercial scale. To determine the both environmental and economic performance, a process simulation model was developed on the SuperPro Designer® platform to simulate the QQ process, and compared to the conventional dry grind model. Results indicate that germ and fiber recovery as done in the QQ process improves the process capacity of a conventional dry grind ethanol facility by approximately 24%. Because of germ and fiber recovery at the front end, the ethanol concentration has been increased to 15% (w/w) as compared to 10.9 (w/w) in the conventional dry grind process. The QQ process reduces the energy and water consumption by 32% and 17.8%, respectively. The QQ process produces more value-added coproducts, including corn germ, corn fiber, and a modified distillers dried grains with solubles (DDGS), but has a lower ethanol yield rate due to some starch losses to the recovered germ and fiber fractions at the front end. A detailed cost and benefit analysis of the QQ process, based on the market prices in April 2009, shows that despite its higher capital investment costs, the QQ process reduces the payback period to 6.5 years, compared to 9.2 years for the conventional dry grind process. Increased ethanol production, more value-added coproducts, as well as significant reduced utility costs are three major contributors to improve the economic performance of the QQ process. This work lays the foundation for the similar studies on the sustainability performance for other modified dry grind ethanol processes.

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

In recent years, there has been a dramatic increase in grain-based fuel ethanol production in North America and around the world. Whether such production will result in a net energy gain or whether this is sustainable in the long term is under debate, but undoubtedly millions of tons of non-fermented residues are now produced annually for global trade in the form of distillers dried grains with solubles (DDGS). Consequently, in a short period of time a tremendous amount of research has been conducted to determine the suitability of ethanol coproducts for various end uses. Distillers Grains: Production, Properties and Utilization is the first book of its kind to provide in-depth, and up-to-date coverage of Historical and current status of the fuel ethanol industry in the U.S. Processing methods, scientific principles, and innovations for making fuel ethanol using grains as feedstock Physical and chemical properties of DDGS, assay methodologies for compositional analyses, and mycotoxin occurrence in DDGS Changes during processing (from grains to DDGS) and analysis of factors causing variations in compositional, nutritional, and physical values Various traditional, new, and emerging uses for DDGS (including feed for cattle, swine, poultry, fish, and other animals, feedstocks for cellulosic ethanol, biodiesel, and other bioenergy production, and substrates for food and industrial uses) Appealing to all who have an interest in fuel ethanol production, distillers grains, and their uses, this comprehensive reference sharpens the readers’ understanding of distillers grains and will promote better utilization of ethanol coproducts. Animal and food scientists, feed and food technologists, ethanol plant managers and technicians, nutritionists, academic and governmental professionals, and college students will find the book most useful.
