Kohl A., Nielsen R. Gas Purification

5th Ed. — Houston: Gulf Publishing Company, 1997. - 1415 р.Руководство по промышленным технологиям разделения газов. На английском языке.Фрагмент предисловия: The aim of this book is to provide a practical engineering description of techniques and processes in widespread use and, where feasible, provide sufficient design and operating data to permit evaluation of the processes for specific applications. Limited data on processes that were once, but are no longer commercially important, are also presented to provide an historical perspective. Subject matter is generally limited to the removal from gas streams of gas phase impurities that are present in relatively minor proportions. The removal of discrete solid or liquid particles is not discussed, nor are processes that would more appropriately be classified as separation rather than purification.A generalized discussion of absorption is provided in Chapter 1 because this unit operation
is common to so m y of the processes described in subsequent chapters. Discussions of
other unit operations employed in gas purification processes, such as adsorption, catalytic
conversion, thermal oxidation, permeation, and condensation are included in the chapters
devoted to these general subjects.No attempt has been made to define the ownership or patent status of the processes
described. Many of the basic patents on well-known processes have expired; however,
patented improvements may be critical to commercial application. In fact, a number of
important proprietary systems are based primarily on the incorporation of special additives
or flow system modifications into previously existing processes.Technical data are normally presented in the units of the original publication. practically,
this means that most U.S. data on commercial operations are given in English units, while
foreign and U.S. scientific data are presented in metric or, occasionally, SI units. To aid in
the conversion between systems, a table of units and conversion factors is included as
an appendix.
