This book is designed to acquaint the reader with current regulations and with the necessary information to size air pollution control systems. The material presented should also help enable one to select the appropriate equipment for retrofit or new process control, to prepare specifications to purchase equipment, and to prepare permits for air pollution control systems. Sizing and Selecting Air Pollution Control Systems provides guidance to help those responsible for air pollution control to specify systems which are cost-effective and energy-efficient to meet the needs of their employers and the government. When equipment specifications are properly prepared, they provide for an easier comparison of competitive bids of those devices capable of meeting standards reliably and economically.
