The rising trend towards the operation of packed towers in separation processes was initiated after the energy crisis in the seventies. This book is the first of its kind which treats all the important theoretical and practical aspects for the calculation, design and operation of these packed towers.

The main applications of packed towers are in the separation of gas-liquid or vapour-liquid systems. This book considers all features of packed towers for industrial separation plants that can be used in process and environmental technology. It includes a comprehensive treatment of packed-bed technology and the advantages of packed towers, such as the application of improved methods for energy saving purposes, environmental protection measures and the revamping of existing plants, are clearly outlined.

The methods presented are based on sound physical and mathematical modelling, the validity of which have been confirmed by numerous experimental investigations performed in laboratories and pilot plants and then scaled up to meet practical, industrial requirements.
