Advances in Natural Gas: Formation, Processing, and Applications is a comprehensive eight-volume set of books that discusses in detail the theoretical basics and practical methods of various aspects of natural gas from exploration and extraction, to synthesizing, processing and purifying, producing valuable chemicals and energy. The volumes introduce transportation and storage challenges as well as hydrates formation, extraction, and prevention Volume 8 titled Process Modelling and Simulation discusses various aspects of natural gas related processes from modelling and simulation point of view. This includes modelling of natural gas sweetening, dehydration and other impurities removal processes and apparatus as well as simulation of processes and apparatus dealt with producing chemicals and energy from natural gas.The book introduces modelling and simulation of natural gas hydrate related processes and covers modelling basics, numerical approaches and optimization techniques, which provides a deeper understanding of the subject.
