Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that California's dairies have the potential to produce an estimates 40 million cubic feet of biogas per day, representing a potential capacity of about 140 mW of energy. Due to the distributed nature of these resources, reciprocating engines coupled to generators are a common means of extracting power from the digester gases. One of the most significant challenges facing the combustion digester biogas is high NOx emissions. To address this challenge, an integrated pollution capture and microwave system has been developed to reduce NOx emissions from biogas engines. The feasibility of reburning the captured NOx was assessed and the various operating parameters, including temperature, pressure and reactants composition were determined using chemical equilibration, kinetic modeling and a Computerized Fluid Dynamic simulation using ANSYS FLUENT software. The NOx removal system is a pair of alternating carbon adsorption vessels installed on the engine exhaust pipe. The carbon will capture cooled exhaust gas NOx and is expected to pass through cleaned exhaust having NOx levels in the range of 1-5 ppm. Each carbon adsorber is equipped with a microwave generator that desorbs the NOx and regenerates the carbon in place when it is isolated from the engine exhaust. Desorbed NOx is collected in a concentrated small volume sweep gas and reacted in a separate microwave activated reactor with consumable carbon to produce CO2 and N2. This system is currently being demonstrated at a dairy facility in Northern California. While the amount and cost of the carbon consumed during the microwave activated NOx reduction step is small, it would be desirable to eliminate this step with another means of NOx destruction. One potential alternative is to use the engine to destroy NOx by dissociation at high temperatures. Traditionally, NOx is formed in the engine by the thermal or prompt mechanisms. However, high concentrations of NOx in the sweep gas would approach equilibrium from the other direction (high concentration to low) and could yield a net NOx reduction. Since the carbon absorber can accept high concentrations of NOx, the absorbers could be used in a potentially sustainable process where NOx is continuously accumulated and destroyed. The objective of the study is to assess the feasibility of this alternate method of NOx destruction using chemical equilibrium, kinetics and computerized fluid dynamic simulations.

Download or read book Biogas Combustion Engines for Green Energy Generation written by Eiji Tomita and published by Springer Nature. This book was released on 2022-02-28 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the combustion and exhaust emissions of gas engines fueled with green biogas. Biogas is a mixture of gases, primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, food waste, etc. Biogas is considered to be a renewable source of energy. Therefore, it can contribute to the prevention of global warming. The biogas engine is used to co-generate electricity by operating engine and heat from hot exhaust gases. The energy source used very efficiently. Unlike other green energy sources such as wind and solar, biogas is readily available when needed. This book first describes the basics of biogas and its application to internal combustion engines. Next, it describes the engine system and the combustion phenomena in the engine cylinder. Engine technology continues to advance in spark ignition and dual-fuel engines to achieve higher thermal efficiency and lower harmful emissions. Several advanced combustion technologies are introduced to achieve higher thermal efficiency while avoiding knocking.

Download or read book Emissions Reduction written by A. Tomita and published by Elsevier. This book was released on 2001-12-18 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade the topic of emissions reduction and control has remained an important area of research due to the enforcement of various Government policies in an attempt to minimize the impact on the environment. One area in which a great deal of research has been conducted to address this policy is NOx/SOx suppression. However, despite the progress that has been made over this time period, further research into the most effective method of reducing NOx/SOx emissions is still urgently required. In developed countries, a more stringent requirement in the level of emissions (such as is NOx/SOx component of less than 10ppm) will be enforced in the near future. Developing countries will also need a new technology that is effective and that is suited to each countries needs. Additional research and development efforts are thus necessary to meet such requirements. This compendium contains a collection of key papers themed around NOx/SOx emissions from combustion of hydrocarbon resources and the attempts to secure an efficient and effective method for reducing these emissions. These key papers are taken from the journals Fuel, Fuel Processing Technology and Progress in Energy and Combustion Science.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on biogas production by anaerobic digestion, which is the most popular bioenergy technology of today. Using anaerobic digestion for the production of biogas is a sustainable approach that simultaneously also allows the treatment of organic waste. The energy contained in the substrate is released in the form of biogas, which can be employed as a renewable fuel in diverse industrial sectors. Although biogas generation is considered an established process, it continues to evolve, e.g. by incorporating modifications and improvements to increase its efficiency and its downstream applications. The chapters of this book review the progress made related to feedstock, system configuration and operational conditions. It also addresses microbial pathways utilized, as well as storage, transportation and usage of biogas.
