Informationen zum Autor C.M. VAN 'T LAND has run the seminar and consulting company Van 't Land Processing since 1999. Prior to that, he worked at Akzo Nobel Chemicals from 1968-2000 as process engineer, and later, process development manager and project leader. He is the author of Industrial Drying Equipment: Selection and Application and Industrial Crystallization of Melts. Klappentext A comprehensive approach to selecting and understanding drying equipment for chemical and mechanical engineersA detailed reference of interest for engineers and energy specialists working in the process industry field, Drying in the Process Industry investigates the current state of the art of today's industrial drying practices, examines the factors influencing drying's high costs in both equipment and energy consumption, and summarizes key elements for keeping drying operations under budget and performing at peak capacity safely while respecting the environment. Extensive coverage of dryer basics as well as essential procedures concerning the selection of industrial dryers-such as how to gather results of relevant laboratory measurements, carry out small-scale tests, and correctly size equipment-help to inform readers on criteria for generating scalable specifications that greatly assist buying decisions.Drying in the Process Industry:* Takes a practical approach to drying equipment, from an author with four decades in the industry* Describes a diverse array of drying equipment (convective, like flash, spray, fluid-bed, and rotary; contact, like paddle and steam; radiation) from an engineer's perspective* Provides quick and ready access to drying technologies with references to more detailed literature* Treats drying in the context of the entire production processTrue of all process facilities where drying plays an important role, such as those in the chemical, pharmaceutical, plastics, and food industries, the purchase of improper industrial drying equipment can significantly affect a manufacturer's economic bottom line. With the guidance offered in this book, engineers will be able to confidently choose industrial drying equipment that increases profits, runs efficiently, and optimally suits their needs. Zusammenfassung Among those interested in drying are chemical engineers, energy specialists, and mechanical engineers. This book assists the process development engineer, the process engineer, and the plant engineer in selecting drying equipment. It discusses the criteria to be observed, the gathering of results of relevant laboratory measurements, the carrying out of small-scale tests (the results of which can be scaled up), and procedures for sizing equipment. Written by an author with over four decades in the process industries, this book brings an extensively practical approach for the engineer.
