Download or read book Economic Evaluation of the MIT Process for Manufacture of Ethanol written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of an economic evaluation of the MIT process for the manufacture of ethanol from cellulosic residues. Conceptual process designs were developed for two cases, Case A which is based on the experimental data obtained to date, and Case B which hypothesizes the suppression of acid byproducts. Manufacturing costs, including profit, were estimated at $12.20/million Btu for Case A and $9.40/million Btu for Case B. These are equivalent to about $1.05 and $0.80/gal ethanol respectively. These economic estimates may be slightly on the low side since they do not consider feedstock storage nor working capital requirements. Nevertheless, the manufacturing costs for Case A appear to be comparable to those of the manufacture of ethanol from corn. The plant size used for this analysis was 1500 ton/day corn stover. This is considered to be a realistic size. The conceptual plants make about 27 million gal/yr ethanol in Case A and 41 million gal/yr in Case B. The MIT process appears to be one of the more promising programs being developed under contract for DOE. It is recommended that the process research be continued. Three areas of concern were identified which must be investigated before the process can be commercialized. First, a satisfactory means of storage of corn stover and other agricultural residues must be developed. Second, a method to sterilize corn stover must be developed or it must be demonstrated that the MIT process can run continuously for extended periods with stover that has been sterilized. Third, research must be done to demonstrate the recycle and reuse of process water.
Download or read book An Economic Study of the Quick germ Technology for the Dry grind Process of Corn Ethanol Production and Its Effects Upon the Corn Oil Market written by Edward Duane Yoder and published by . This book was released on 2006 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019-09-17 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book An Economic Analysis of Corn based Ethanol Production written by Won W. Koo and published by . This book was released on 2008 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A global multi-commodity simulation model was developed to estimate the impact of changes in ethanol production on the U.S. corn industry. ... The increased price of corn leads to major structural changes in the corn industry in the United States as well as other corn producing and consuming countries. Corn production would increase in response to higher price levels, corn used for livestock feed may decrease, and U.S. exports decrease due mainly to a surge in corn used for ethanol production. This decrease in U.S. exports should be met by additional production in other countries. The increased price of corn also leads to increases in the prices of soybeans, wheat, high fructose corn syrup (HFCS), and agricultural inputs, such as land value and cash rent, fertilizer and chemicals, and farm equipment. In addition, the current price of corn has resulted in an increase in the production cost of livestock. The increase in prices of agricultural commodities and inputs would cause increases in retail prices of food in the U.S.

Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Download or read book A Life Cycle Assessment and Techno economic Analysis of a Corn Ethanol Bio Refinery in Comparison to a Novel Bio refinery written by Daniel Gerrior and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A life cycle assessment and economic analysis of a dry-mill corn-ethanol facility was completed and compared to a novel bio-refinery. The novel facility is able to avoid additional energy intensive treatment through anaerobic digestion. The effluent from the digester is then aerobically treated before being utilized for the cultivation of Chlorella sorokiniana, which will be used to supplement the corn required for the biorefinery. The biorefinery was proposed in order to reduce the corn input, energy consumption and GHG emissions associated with ethanol production. An economic analysis was also completed to determine the changes to capital and operational costs for the novel biorefinery. The results show a reduction in energy use and increased co-product production led to decreases in most environmental impact categories for the novel biorefinery. The economic analysis indicated that the overall revenue decreased in the novel biorefinery when capital, operating and material costs were taken into consideration.
