Book Cellulosic Ethanol from Wood Chips Cost Analysis Ethanol E51A

Download or read book Cellulosic Ethanol from Wood Chips Cost Analysis Ethanol E51A written by Intratec and published by Intratec Solutions. This book was released on 2016-05-01 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of second generation Ethanol production from wood chips via a thermochemical process. The process examined is similar to the one reported by the National Renewable Energy Laboratory (NREL). In this process, biomass is subjected to gasification generating syngas, which is then converted to hydrous Ethanol. The process employs concepts similar to those proposed in patents issued to Range Fuels. Mixed alcohols are generated as by-products. 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): Phillips, S., et al., "Thermochemical Ethanol via Indirect Gasification and Mixed Alcohol Synthesis of Lignocellulosic Biomass, " Report NREL/TP-510-41168, National Renewable Energy Laboratory (NREL), 2007 Keywords: Ethyl Alcohol, Bioethanol, Lignocellulosic Biomass, 2nd Generation, Cellulosic Sugar, Hemicelluloses, Cellulose

Book Economic Analysis of Ethanol Production from Biomass Using a Hybrid Thermal biological Conversion Process

Download or read book Economic Analysis of Ethanol Production from Biomass Using a Hybrid Thermal biological Conversion Process written by Kim Sui So and published by . This book was released on 1998 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this case study is to examine the economics of ethanol production using the Waterloo Fast Pyrolysis process integrated with a fermentation step. The raw materials considered are wood and switchgrass. The pyrolytic ethanol process is evaluated in terms of capital costs, operating costs, and ethanol production costs for each type of feedstocks used. Sensitivity analyses are carried out to study the uncertainties of feedstock costs, ethanol production rates and ethanol yields on ethanol production costs. The economics of pyrolytic ethanol is compared to two other widely-known processes: simultaneous saccharification and fermentation, and dilute acid hydrolysis and fermentation. This analysis indicates that the pyrolytic ethanol process is comparable with the other two processes and suggests that it should be considered for further development.

Book Techno economic Analysis for the Thermochemical Conversion of Lignocellulosic Biomass to Ethanol Via Acetic Acid Synthesis

Download or read book Techno economic Analysis for the Thermochemical Conversion of Lignocellulosic Biomass to Ethanol Via Acetic Acid Synthesis written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass is a renewable energy resource that can be converted into liquid fuel suitable for transportation applications. As a widely available biomass form, lignocellulosic biomass can have a major impact on domestic transportation fuel supplies and thus help meet the Energy Independence and Security Act renewable energy goals (U.S. Congress 2007). This study performs a techno-economic analysis of the thermo chemical conversion of biomass to ethanol, through methanol and acetic acid, followed by hydrogenation of acetic acid to ethanol. The conversion of syngas to methanol and methanol to acetic acid are well-proven technologies with high conversions and yields. This study was undertaken to determine if this highly selective route to ethanol could provide an already established economically attractive route to ethanol. The feedstock was assumed to be wood chips at 2000 metric ton/day (dry basis). Two types of gasification technologies were evaluated: an indirectly-heated gasifier and a directly-heated oxygen-blown gasifier. Process models were developed and a cost analysis was performed. The carbon monoxide used for acetic acid synthesis from methanol and the hydrogen used for hydrogenation were assumed to be purchased and not derived from the gasifier. Analysis results show that ethanol selling prices are estimated to be $2.79/gallon and $2.81/gallon for the indirectly-heated gasifier and the directly-heated gasifier systems, respectively (1stQ 2008$, 10% ROI). These costs are above the ethanol market price for during the same time period ($1.50 - $2.50/gal). The co-production of acetic acid greatly improves the process economics as shown in the figure below. Here, 20% of the acetic acid is diverted from ethanol production and assumed to be sold as a co-product at the prevailing market prices ($0.40 - $0.60/lb acetic acid), resulting in competitive ethanol production costs.

Book Evaluation of Processes for Producing Gasoline from Wood Final Report

Download or read book Evaluation of Processes for Producing Gasoline from Wood Final Report written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three processes for producing gasoline from wood by pyrolysis have been investigated. Technical and economic comparisons among the processes have been made, based on a hypothetical common plant size of 2000 tons per day green wood chip feedstock. In order to consider the entire fuel production process, the energy and cost inputs for producing and delivering the feedstock were included in the analysis. In addition, perspective has been provided by comparisons of the wood-to-gasoline technologies with other similar systems, including coal-to-methanol and various biomass-to-alcohol systems. Based on several assumptions that were required because of the candidate processes' information gaps, comparisons of energy efficiency were made. Several descriptors of energy efficiency were used, but all showed that methanol production from wood, with or without subsequent processing by the Mobil route to gasoline, appears most promising. It must be emphasized, however, that the critical wood-to-methanol system remains conceptual. Another observation was that the ethanol production systems appear inferior to the wood-to-gasoline processes. Each of the processes investigated requires further research and development to answer the questions about their potential contributions confidently. The processes each have so many unknowns that it appears unwise to pursue any one while abandoning the others.
