tailieunhanh - Gas Purification

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 pvide an histor - ical 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 sol- id or liquid particles is not discussed, nor are processes that would more appropriately be classified as separation rather than purification.
