Hardback. Condition: New. 1st. Pressure Swing Adsorption is the first book that provides a coherent and concise summary of the underlying science and technology of pressure swing adsorption (PSA) processes at a level understandable to the practising engineer. PSA has achieved widespread commercial acceptance as the technology of choice for hydrogen purification, air separation and small scale air driers. However, PSA has numerous other actual and potential uses such as the recovery of methane from landfill gas, the production of carbon dioxide and other large scale applications. Since the design and optimization of a PSA process requires a somewhat mathematical model, two chapters of the book provide in-depth information on equilibrium theory and dynamic numerical simulation. However, this mathematical material will also help the general reader develop an understanding of the principles and strenghts and limitations of various approaches. PSA engineers, chemical engineers, environmental chemists, academicians and managers who must make informed decisions about purchasing costly PSA systems will find Pressure Swing Adsorption of particular value.…
