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 4 titled Natural Gas Dehydration introduces in detail different natural gas dehydration methods. The book covers absorption with different solvents such as glycols, ionic liquids, and DES which is one of the important dehydration techniques, as well as natural gas dehydration with adsorption-based technologies utilizing various materials including zeolites, carbonaceous sorbents, metal oxides, etc. It discusses in detail membrane-based processes with various types (such as hollow-fiber and polymeric membranes) and includes novel technologies for sweetening natural gas by using supersonic technology.
