Coal is currently a major energy source in the United States as well as throughout the world, especially among many developing countries, and will continue to be so for many years. Fossil fuels will continue to be the dominant energy source for fueling the United States economy, with coal playing a major role for decades. Coal provides stability in price and availability, will continue to be a major source of electricity generation, will be the major source of hydrogen for the coming hydrogen economy, and has the potential to become an important source of liquid fuels. Conservation and renewable/sustainable energy are important in the overall energy picture, but will play a lesser role in helping us satisfy our energy demands. This book is a single source covering many coal-related subjects of interest ranging from explaining what coal is, where it is distributed and quantities it can be found in throughout the world, technical and policy issues regarding the use of coal, technologies used and under development for utilizing coal to produce heat, electricity, and chemicals with low environmental impact, vision for untilizing coal well into the 21st century, and the security coal presents.* Presents coal's increasing role in providing energy independence to nations* Covers current energy usage, environmental issues, and coal energy technologies* Provides a comprehensive discussion of technical and policy issues regarding the use of coal
Clean Coal Engineering Technology, Second Edition provides significant information on the major power generation technologies that aim to utilize coal more efficiently, and with less environmental impact. With increased coal combustion comes heightened concerns about coal's impacts on human health and climate change, so the book addresses the reduction of both carbon footprints and emissions of pollutants, such as particulate matter, nitrogen oxides, and mercury. Part 1 provides an essential grounding in the history of coal use alongside coal chemical and physical characteristics, worldwide distribution, and health and environmental impacts. Part 2 introduces the fundamentals of the major coal utilization technologies and examines the anatomy of a coal-fired power plant before going on to provide an overview of clean coal technologies for advanced power generation. Next, users will find a group of chapters on emissions and carbon management that have been extensively enlarged and updated for the second edition, thus reflecting the ever-increasing importance of this area. The final section of the book focuses on clean coal technology programs around the world and the future role of coal in the energy mix. This fully revised and selectively expanded new edition is a valuable resource for professionals, including environmental, chemical, and mechanical engineers who seek an authoritative and thorough one-volume overview of the latest advances in cleaner power production from coal. - Provides a thorough, yet readable, one-volume guide to advanced power generation technologies for cleaner electricity production from coal - Retains the essential background information on coal characteristics and the fundamentals of coal-fired power generation - Presents extensively expanded and updated coverage on technologies for the reduction of pollutants, including particulate matter, sulfur oxides, and mercury - Emphasizes carbon capture methods, storage, and emerging technologies for the reduction of carbon footprints, alongside a discussion of coal's future in the energy mix
Coal accounts for approximately one quarter of world energy consumption and of the coal produced worldwide approximately 65% is shipped to electricity producers and 33% to industrial consumers, with most of the remainder going to consumers in the residential and commercial sectors. The total share of total world energy consumption by coal is expected to increase to almost 30% in 2035. This book describes the challenges and steps by which electricity is produced form coal and deals with the challenges for removing the environmental objections to the use of coal in future power plants. New technologies are described that could virtually eliminate the sulfur, nitrogen, and mercury pollutants that are released when coal is burned for electricity generation. In addition, technologies for the capture greenhouse gases emitted from coal-fired power plants are described and the means of preventing such emissions from contributing to global warming concerns. Written by one of the world’s leading energy experts, this volume is a must-have for any engineer, scientist, or student working in this field, providing a valuable reference and guide in a quickly changing field.
This reference book addresses the evolution of materials for both oxygen and hydrogen transport membranes and offers strategies for their fabrication as well as their subsequent incorporation into catalytic membrane reactors. Other chapters deal with, e.g., engineering design and scale-up issues, strategies for preparation of supported thin-film membranes, or interfacial kinetic and mass transfer issues. A must for materials scientists, chemists, chemical engineers and electrochemists interested in advanced chemical processing.
This essential handbook and ready reference offers a detailed overview of the existing and currently researched technologies available for the control of mercury in coal-derived gas streams and that are viable for meeting the strict standards set by environmental protection agencies. Written by an internationally acclaimed author team from government agencies, academia and industry, it details US, EU, Asia-Pacific and other international perspectives, regulations and guidelines.
From Methane to Hydrogen-Making the Switch to a Cleaner Fuel Source The world's overdependence on fossil fuels has created environmental problems, such as air pollution and global warming, as well as political and economic unrest. With water as its only by-product and its availability in all parts of the world, hydrogen promises to be the next grea

Fossil-fuel power plants account for the majority of worldwide power generation. Increasing global energy demands, coupled with issues of ageing and inefficient power plants, have led to new power plant construction programmes. As cheaper fossil fuel resources are exhausted and emissions criteria are tightened, utilities are turning to power plants designed with performance in mind to satisfy requirements for improved capacity, efficiency, and environmental characteristics.Advanced power plant materials, design and technology provides a comprehensive reference on the state of the art of gas-fired and coal-fired power plants, their major components and performance improvement options. Part one critically reviews advanced power plant designs which target both higher efficiency and flexible operation, including reviews of combined cycle technology and materials performance issues.Part two reviews major plant components for improved operation, including advanced membrane technology for both hydrogen (H2) and carbon dioxide (CO2) separation, as well as flue gas handling technologies for improved emissions control of sulphur oxides (SOx), nitrogen oxides (NOx), mercury, ash and particulates. The section concludes with coverage of high-temperature sensors, and monitoring and control technology that are essential to power plant operation and performance optimisation.Part three begins with coverage of low-rank coal upgrading and biomass resource utilisation for improved power plant fuel flexibility. Routes to improve the environmental impact are also reviewed, with chapters detailing the integration of underground coal gasification and the application of carbon dioxide (CO2) capture and storage. Finally, improved generation performance is reviewed with coverage of syngas and hydrogen (H2) production from fossil-fuel feedstocks.With its distinguished international team of contributors, Advanced power plant materials, design and technology is a standard reference for all power plant engineers and operators, as well as to academics and researchers in this field. - Provides a comprehensive reference on the state-of-the-art gas-fired and coal-fired power plants, their major components and performance improvement options - Examines major plant components for improved operation as well as flue gas handling technologies for improved emissions control - Routes to improve environmental impact are discussed with chapters detailing the integration of underground coal gasification
