Biomethane Production from Vegetable and Water Hyacinth Waste explores the production of biomethane from vegetable waste and water hyacinth via anaerobic fermentation, focusing on effect factors, control methods and optimization. The book introduces principles and key technologies before proceeding into a deeper exploration of the fundamentals of municipal vegetable waste, such as composition, main indicators, experiment devices, and pretreatment. Processes to produce volatile fatty acids and resource recovery from anaerobic fermentation liquid and residue are described in detail. Other topics covered include the utilization of fermentation products, engineering design of a reaction tank, process parameters, and environmental and economic aspects. The practical, application-oriented approach of this book allows engineering researchers, PhD students, and industry practitioners in the field of biogas and biomethane production, biomass conversion, and waste management to immediately utilize the information it provides. - Covers the fundamentals and applications of the use of food waste and water hyacinth for biomethane production through anaerobic digestion - Explores core challenges of a biomethane production operation, including details on process optimization and control - Includes multiple case studies grounded in current industrial practice - Offers practical examples and numerical calculations for large-scale operation - Provides a representative treatment of a PPP plant considered from a process systems design perspective

This book brings together recent research from across the world on enriched methane, and examines the production, distribution and use of this resource in internal combustion engines and gas turbines. It aims to provide readers with an extensive account of potential technological breakthroughs which have the capacity to revolutionize energy systems. Enriched methane, a gas mixture composed by methane and hydrogen (10-30%vol), constitutes the first realistic step towards the application of hydrogen as an energy vector. It provides strong benefits in terms of emissions reduction, that is -11% of CO2, eq emission with the combustion of a 30%vol H2 mixture, if hydrogen is produced from renewable energy sources. Enriched methane offers the following advantages:• it can be produced at competitive costs; • it can be distributed by means of the medium pressure natural gas grid;• it can be stored in traditional natural gas storage systems; <• it can feed natural gas internal combustion engine, improving conversion efficiency. This book is intended for academics in chemical engineering and energy production, distribution and storage. It is also intended for energy producers, engineering companies and R&D organizations.
