Full Description
In recent years, interest in the technology of gas cleaning at high temperatures has grown, driven in part by environmental legislation but also by demands for increases in process efficiency and intensity - notably for power generation and waste incineration. Some techniques for high temperature gas cleaning have now reached practical exploitation, and industrial applications are described by some of the contributors to this volume. This book should be of interest to all in the process industries and in the associated research community who are concerned with collecting particulates and gaseous components at temperatures above 200 degrees centigrade. Many of the major industrial trials of hot gas cleaning techniques since 1986, in both North America and Europe, are included. In particular, authors from both academic and industrial sectors consider: developments in processes and devices to remove particles from hot gas streams; measurement and analysis of particulate and gaseous components; combined processes for the removal of vapours and acid gases using "dry scrubbing" and related techniques; and applications in the process industries and in advanced power generation.
This book should be of interest to chemical and process engineers in the industrial and academic sectors.
