Biological and chemical parameters and life cycle assessment of the integrated generation of solid fuel and biogas from biomass ab 15 EURO
This book presents the state of the art in biogas production using anaerobic digestion technology, with an emphasis on waste utilization/valorization. Offering a comprehensive reference guide to biogas production from different waste streams, it covers various aspects of anaerobic digestion technology from the basics, i.e., microbiological aspects to prominent parameters governing biogas production systems, as well as major principles of their operation, analysis, process control, and troubleshooting. Written and edited by internationally recognized experts in the field of biogas production from both academia and industry, it provides in-depth and cutting-edge information on central developments in the field. In addition, it discusses and reviews major issues affecting biogas production, including the type of feedstock, pretreatment techniques, production systems, design and fabrication of biogas plants, as well as biogas purification and upgrading technologies. 'Biogas: Fundamentals, Process, and Operation' also addresses the application of advanced environmental and energy evaluation tools including life cycle assessment (LCA), exergy, techno-economics, and modeling techniques.
Irrecoverable rapid depletion of petroleum reserves, high price fluctuations, uncertainty in supply to consuming nations, high expenditure on fuel import, harmful effects of various exhaust emission on the human being and environment sorces to search for alternative fuels that they themselves can produce. These alternative fuels should be preferably available from renewable sources. Therefore, attention is mainly focused towards biomass- based fuels. Alternative considered are ethanol, methanol, biogas and vegetable oil, methyl or ethyl ester of vegetable oil (biodiesel).Karanja bio-diesel production should be improved according to higher environmental impacts than the conventional diesel fuel from life cycle aspects.
The book Analysis of a Commercial Thermophilic Biogas Plant is a product of a research that identified biodegradable waste materials like domestic/municipal effluence as economically viable alternative source of energy. The proposed Commercial biogas plant was mathematically modeled for urban area clean energy requirement. The capacity of the plant was estimated for a given cycle of operation. A nominal 1500m3 power gas plant was studied characteristically and its performance efficiency evaluated. It was observed that the rate of biogas production is a function of the reactor temperature, pH, substrate concentration, rate of degradation of biomass, and the accumulation of matter in the system due to bacteria growth.
This book is compiled jointly by the Tajikistan and Pakistani scientists based on the result of research and various designs of photovoltaics, wind-power systems, biogas digestors and micro-hydropower systems. The economics of these renewable energy installations that are widespread in different countries in the world for the last decade are described and highlighted. Authors believe that this book will provide understanding of the basic points of the economics of the renewable energy installations and will be a useful source for students, researchers and professionals. In particular, in this book the concept of life-cycle cost (LCC), calculations of present worth, annual life-cycle cost (ALCC) and unit electricity cost are described. For the various designs of photovoltaics, wind-power systems, biogas digestors and micro-hydropower systems the unit electricity costs are calculated. Taking into account that the renewable energy installations usually have less effect to the environment, the concept of total cost of the energy is also described.
Gasification is not new in India and China. Gasifiers in different forms were used for cooking foods. During the Arab Oil Embargo of 1973 the U.S. Government provided financial support for several proof-of-concept gasification projects, including the world's first Integrated Gasification Combined Cycle (IGCC) electric power plant. Presently, several IGCC power plants are operating throughout the world. The book, Gasification System is a compilation of research based literatures useful to students, scholars, scientists and engineers and help in integrating the advance technology that will contribute in production of energy for filling the gap between available and needed energy. The book covers most recent technologies on gasifiers and biogas in 9 chapters, Introduction, Gasification System, History of Gasification, Biogas Technology, Development of Biogas Plant, Mathematical Modeling of Gasification System, Design of Gasification System, Commercialization of Gasification System and Testing and Evaluation of Gasification System. It may be a useful book having up-to-date information on the subject.
Today's bioenergy systems are frequently characterised by limited conversion efficiency and dependencies on few species of energy crops leading to low biodiversityin plant production. With the aim to improve the ecological performance of biomass production and processing and to convert a wider spectrum of biomass resources, the integrated generation of solid fuel and biogas from biomass (IFBB) was developed. Its core element is the mechanical separation of the wet conserved biomass into a solid fuel for combustion and a liquid for anaerobic digestion with subsequent production of heat and electricity from the biogas. This study investigated biological and chemical parameters of the IFBB process. Furthermore, life cycle assessment was conducted to evaluate the overall energy efficiency as well as saving potentials of fossil primary energy and emissions of greenhouse gases of the IFBB process along the entire process chain.
Governments are setting challenging targets to increase the production of energy and transport fuel from sustainable sources. The emphasis is increasingly on renewable sources including wind, solar, geothermal, biomass based biofuel, photovoltaics or energy recovery from waste. What are the environmental consequences of adopting these other sources? How do these various sources compare to each other? Life Cycle Assessment of Renewable Energy Sources tries to answer these questions based on the universally adopted method of Life Cycle Assessment (LCA). This book introduces the concept and importance of LCA in the framework of renewable energy sources and discusses the key issues in conducting their LCA. This is followed by an in-depth discussion of LCA for some of the most common bioenergy sources such as agricultural production systems for biogas and bioethanol, biogas from grass, biodiesel from palm oil, biodiesel from used cooking oil and animal fat, Jatropha biodiesel, lignocellulosic bioethanol, ethanol from cassava and sugarcane molasses, residential photovoltaic systems, wind energy, microalgal biodiesel, biohydrogen and biomethane. Through real examples, the versatility of LCA is well emphasized. Written by experts all over the globe, the book is a cornucopia of information on LCA of bioenergy systems and provides a platform for stimulation of new ideas and thoughts. The book is targeted at practitioners of LCA and will become a useful tool for researchers working on different aspects of bioenergy.
