Bleach Plant Pumping System Optimization Case Study

Increasing energy prices are pushing plant operating costs higher. This increase is due to record electricity use in North America. New power plant construction and ever-increasing fuel costs will further increase the price of electricity. Industrial motor systems are the single largest electrical end use category in the American economy; motors account for 25% of U.S. electrical sales. These values come from the United States Industrial Motor Systems Market Opportunities Assessment, 1998 (DOE). Over 60% of industrial motor-system energy consumption involves fluid handling. Pumps, fans, compressed air, and refrigeration devices account for 36.8% of the industrial population, but 61.0% of the industrial motor energy consumption. A small fraction of the motor population is responsible for most of the energy consumption. Energy is the dominant cost of ownership. This paper will address total pumping system optimization with an emphasis on improved Life Cycle Costing using speed control.
