A gaseous or liquid propellant is used to push the pig through the system. This strategy avoids rinsing loss of valuable product, provides reduction of adverse environmental impacts, and gains high efficiency for less investment. The book describes clearly and methodically the important basic equipment required for the planning and design of pigging units. Many practical examples are shown for the operation of industrial pigging units, drawn from the authors′ longtime experience in this technology. In this form and scope the book is an unrivaled presentation of this technology. Engineers and chemists who plan, construct, operate and maintain production plants in the chemical, food, cosmetics, pharmaceutical and petrochemical industry will find an invaluable source of advice and reference for pigging units."If I had had this book about the complex subject of pigging technology at an earlier date, I could have saved myself much work." (Chemical Engineering Technology) "As a summary I conclude that this book is recommendable for anyone searching for a detailed introduction to this technology. Furthermore, it is a valuable guide for all engineers dealing with the planning of industrial chemical plants." (Chemie Technik)
