An original and up-to-date discussion of a promising sustainable energy technology
In Sustainable Polygeneration based on Carbon Capture and Utilisation, Falah Alobaid and Bernd Epple present a comprehensive and authoritative investigation of state-of-the-art technologies for converting solid fuels, including both fossil fuels and biomass, into energy services, chemicals, and other valuable products. The book covers advanced combustion, gasification, pyrolysis, hydrothermal processes, and steam reforming, integrating these conversion methods with Carbon Capture and Utilisation (CCU) technologies. It also examines the numerical simulation of polygeneration plants using one-dimensional process models, both steady-state and dynamic, as well as three-dimensional CFD models, highlighting their applications in system design, optimisation, and performance evaluation.
Organised into four major thematic areas, the book begins with an in-depth treatment of conversion processes for solid fuels, followed by a detailed exploration of carbon capture and utilisation technologies for emission sources. It then presents sustainable polygeneration plants before concluding with a thorough examination of the mathematical and computational models used for polygeneration plant simulations. The text is enriched with experimental results from one of the world’s largest research pilot plants, providing real-world performance data that validates key technologies and demonstrates the practical integration of conversion, capture, and utilisation processes.
Ideal for chemical engineers, process engineers, industrial chemists, and environmental engineers, Sustainable Polygeneration based on Carbon Capture and Utilisation combines theoretical foundations with practical insights, making it an essential resource for both researchers and practitioners.
