In recent years, interest in the technology of gas cleaning has grown, driven partly by environmental legislation, but also by demands for increases in process efficiency and intensity - notable for power generation and waste incineration. This book, which leads on from our successful Gas Cleaning at High Temperatures, describes the present state of the art and its industrial applications.

This volume comprises the papers presented at the Second International Symposium on Gas Cleaning at High Temperatures, held at the University of Surrey, Guildford, UK on 27-29 September, 1993. The Symposium was organised by the Department of Chemical and Process Engineering and the Centre for Environmental Strategy of the University of Surrey, and co-sponsored by The Institution of Chemical Engineers, The Filtration Society and the Royal Society of Chemistry.

Over half of the products of the chemical and process industries are sold in a particulate form. The range of such products is vast: from agrochemicals to pigments, from detergents to foods, from plastics to pharmaceuticals. However, surveys of the performance of processes designed to produce particulate products have consistently shown inadequate design and poor reliability. Particle technology' is a new subject facing new challenges. Chemical and process engineering is becoming less concerned with the design of plants to produce generic simple chemicals (which are often single phase fluids) and is now more concerned with speciality effect' chemicals which may often be in particulate form. Chemical and process engineers are also being recruited in increasing numbers into areas outside their tranditional fields, such as the food industry, pharmaceuticals and the manufacture of a wide variety of consumer products. This book has been written to meet their needs. It provides comprehensive coverage of the technology of particulate solids, in a form which is both accessible and concise enough to be useful to engineering and science students in the final year of an undergraduate degree, and at Master's level. Although it was written with students of chemical engineering in mind, it will also be of use and interest to students of other disciplines. It comprises an account of the fundamentals of teh subject, illustrated by worked examples, and followed by a wide range of selected applications.
