Book Description
This comprehensive and up-to-date handbook on this highly topical field, covering everything from new process concepts to commercial applications. Describing novel developments as well as established methods, the authors start with the evaluation of different oxygen carriers and subsequently illuminate various technological concepts for the energy conversion process. They then go on to discuss the potential for commercial applications in gaseous, coal, and fuel combustion processes in industry. The result is an invaluable source for every scientist in the field, from inorganic chemists in academia to chemical engineers in industry.

Book Description
Chemical-looping combustion (CLC) for coal is a zero-emission technology, combining very low efficiency penalty and low CO2 capture cost. The ACCLAIM project involved experimental activities in five CLC pilots ranging from 0.5 kW to 1 MW, as well as laboratory investigations, studies in a cold-flow model, modelling and technology assessments. The operational experiences gained in the five pilots were significant, clearly indicating the viability of this novel combustion principle, providing important understanding of the process and giving a solid basis for process modelling. For example, the prequalification of oxygen carriers indicated that several low-cost materials are able to improve gas conversion as compared to previously tested ilmenite. In the 100 kW unit, operation with mixed oxygen carriers showed that a 10% addition of manganese ore to ilmenite could almost halve the fraction of unconverted gas. Moreover, the fate of fuel contaminants like sulfur and nitrogen was investigated. Different oxygen carriers and fuels were investigated in two different configurations of the 1 MWth pilot and the performance with ilmenite was slightly better than with iron ore. Mathematical modelling and cold-flow modelling showed possible ways of increasing process performance by modification of process or reactor design, and for example the benefical effect of internals was verified in operation of a 50 kWth pilot. An overall efficiency of 42% was calculated by process simulations for a full scale CLC power plant. The CO2 capture cost was 27 €/ton, and the increase in cost of electricity, compared to a reference case, was 36%.

Book Description
This book presents the current carbonaceous fuel conversion technologies based on chemical looping concepts in the context of traditional or conventional technologies. The key features of the chemical looping processes, their ability to generate a sequestration-ready CO2 stream, are thoroughly discussed. Chapter 2 is devoted entirely to the performance of particles in chemical looping technology and covers the subjects of solid particle design, synthesis, properties, and reactive characteristics. The looping processes can be applied for combustion and/or gasification of carbon-based material such as coal, natural gas, petroleum coke, and biomass directly or indirectly for steam, syngas, hydrogen, chemicals, electricity, and liquid fuels production. Details of the energy conversion efficiency and the economics of these looping processes for combustion and gasification applications in contrast to those of the conventional processes are given in Chapters 3, 4, and 5.Finally, Chapter 6 presents additional chemical looping applications that are potentially beneficial, including those for H2 storage and onboard H2 production, CO2 capture in combustion flue gas, power generation using fuel cell, steam-methane reforming, tar sand digestion, and chemicals and liquid fuel production. A CD is appended to this book that contains the chemical looping simulation files and the simulation results based on the ASPEN Plus software for such reactors as gasifier, reducer, oxidizer and combustor, and for such processes as conventional gasification processes, Syngas Chemical Looping Process, Calcium Looping Process, and Carbonation-Calcination Reaction (CCR) Process. Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.

Book Description
Oxy-fuel combustion is currently considered to be one of the major technologies for carbon dioxide (CO2) capture in power plants. The advantages of using oxygen (O2) instead of air for combustion include a CO2-enriched flue gas that is ready for sequestration following purification and low NOx emissions. This simple and elegant technology has attracted considerable attention since the late 1990s, rapidly developing from pilot-scale testing to industrial demonstration. Challenges remain, as O2 supply and CO2 capture create significant energy penalties that must be reduced through overall system optimisation and the development of new processes.Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture comprehensively reviews the fundamental principles and development of oxy-fuel combustion in fossil-fuel fired utility boilers. Following a foreword by Professor János M. Beér, the book opens with an overview of oxy-fuel combustion technology and its role in a carbon-constrained environment. Part one introduces oxy-fuel combustion further, with a chapter comparing the economics of oxy-fuel vs. post-/pre-combustion CO2 capture, followed by chapters on plant operation, industrial scale demonstrations, and circulating fluidized bed combustion. Part two critically reviews oxy-fuel combustion fundamentals, such as ignition and flame stability, burner design, emissions and heat transfer characteristics, concluding with chapters on O2 production and CO2 compression and purification technologies. Finally, part three explores advanced concepts and developments, such as near-zero flue gas recycle and high-pressure systems, as well as chemical looping combustion and utilisation of gaseous fuel.With its distinguished editor and internationally renowned contributors, Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture provides a rich resource for power plant designers, operators, and engineers, as well as academics and researchers in the field. - Comprehensively reviews the fundamental principles and development of oxy-fuel combustion in fossil-fuel fired utility boilers - Provides an overview of oxy-fuel combustion technology and its role in a carbon-constrained environment - Introduces oxy-fuel combustion comparing the economics of oxy-fuel vs. post-/pre-combustion CO2 capture
