Available in PDF, EPUB and Kindle. Book excerpt: This study provides cost estimates for the pretreatment/digestion of crop residues to fuel gas. Agricultural statistics indicate that the crop residues wheat straw, corn stover, and rice straw are available in sufficient quantity to provide meaningful supplies of gas. Engineering economic analyses were performed for digestion of sheat straw, corn stover, and rice straw for small farm, cooperative, and industrial scales. The results of the analyses indicate that the production of fuel gas from these residues is, at best, economically marginal, unless a credit can be obtained for digester effluent. The use of pretreatment can double the fuel gas output but will not be economically justifiable unless low chemical requirements or low-cost chemicals can be utilized. Use of low-cost hole-in-the-ground batch digestion results in improved economics for the small farm size digestion system, but not for the cooperative and industrial size systems. Recommendations arising from this study are continued development of autohydrolysis and chemical pretreatment of agricultural crop residues to improve fuel gas yields in an economically feasible manner; development of a low-cost controlled landfill batch digestion process for small farm applications; and determination of crop residue digestion by-product values for fertilizer and refeed.

A review of agricultural statistics indicated that the crop residues wheat straw, corn stover, and rice straw are available in sufficient quantity to provide meaningful supplies of gas. Engineering economic analyses were performed for digestion of wheat straw, corn stover, and rice straw for small farm-, cooperative-, and industrial scales. The small farm scale processed the residue from an average size US farm (400 acres), and the other sizes were two and three orders of magnitude greater. The results of the analyses indicate that the production of fuel gas from these residues is, at best, economically marginal, unless a credit can be obtained for digester effluent. The use of pretreatment can double the fuel gas output but will not be economically justifiable unless low chemical requirements or low cost chemicals can be utilized. Additional development is necessary in this area. Use of low cost hole-in-the-ground batch digestion results in improved economics for the small farm size digestion system, but not for the cooperative and industrial size systems. Recommendations arising from this study are continued development of autohydrolysis and chemical pretreatment of agricultural crop residues to improve fuel gas yields in an economically feasible manner; development of a low cost controlled landfill batch digestion process for small farm applications; and determination of crop residue digestion by-product values for fertilizer and refeed.

Download or read book Feasibility Study of Anaerobic Digestion of Food Waste in St. Bernard, Louisiana. A Study Prepared in Partnership with the Environmental Protection Agency for the RE-Powering America's Land Initiative: Siting Renewable Energy on Potentially Contaminated Land and Mine Sites written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) developed the RE-Powering America's Land initiative to re-use contaminated sites for renewable energy generation when aligned with the community's vision for the site. The former Kaiser Aluminum Landfill in St. Bernard Parish, Louisiana, was selected for a feasibility study under the program. Preliminary work focused on selecting a biomass feedstock.Discussions with area experts, universities, and the project team identified food wastes as the feedstock and anaerobic digestion (AD) as the technology.

Download or read book Feasibility Study of Running an Anaerobic Digestion Plant Coupled with a Combined Heat and Power Plant Near Paris, France, Processing 50,000 Tons of Food Waste Per Year written by Pierre-marie Olivard and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations worldwide continue to expand, waste production and management solutions are being reexamined to address global climate change issues. The objective of this work was to determine whether constructing and running an anaerobic plant including electricity and heat production was a feasible project. The plant would be located near Paris, France, and process food waste. This work answers to both waste management and energy production related issues. Anaerobic digestion is a natural process during which organic matter is decomposed, producing biogas rich in methane and a digestate which can be utilized as fertilizer. This biogas is then combusted and its energy recovered. The first part of this study focuses on the process of anaerobic digestion itself. Important parameters are identified such as moisture, pH, temperature or C:N ratio of the material to process. A review of the current available technologies is conducted, identifying different operation modes. These operation modes can differ in several ways, such as the rate of feeding of the digester, the period of time the matter stays in the digester, or the number of stages the process is divided into (i.e. whether the digestion occurs in 1, 2, or more different containers). Also, the amount of methane obtained as output of the digestion process depends on the initial composition of the material. Previous studies made it possible to link different inputs with the expected quantity of methane produced. Based on research results and industrial data, a sizing model was developed. It calculates every flux of matter going in and out of a theoretical digestion plant. For a given input material, the model returns estimations of the biogas, energy, and fertilizer production. This model is applied for the project feasibility study, considering two different technologies: a wet and a dry process. The results obtained are used to conduct an economical and environmental analysis, before concluding on the feasibility of the project. Considering this specific project, the dry process is preferred from every point of view. Despite the extra costs generated, the project would be a sustainable waste management solution for the municipality, in line with present energetic and environmental concerns.

Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion is a biological process in which bacteria break down organic matter to produce methane, partially stabilized effluent, and other products. although the process has been advocated as a source of fuel, feed, and fertilizer, its widespread adoption in American agriculture is doubtful. the cost and complexity of most digestive systems make them difficult to incorporate in agricultural operations. although site specific applications may be feasible, these will not have a major impact on the agricultural sector. as a source of energy, there is little possibility of anaerobic digestion providing even a small percentage of national energy requirements.
