Abstract:
A comprehensive approach to selecting and understanding drying equipment for chemical and mechanical engineers A 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 process True 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.
