Pump Energy Conservation Techniques

Abstract

Thousands of dollars are wasted annually in a typical petrochemical plant through inefficient operation of pumps. Excess capacity, changing operating conditions, inefficient control, and inadequate maintenance are some of the more common sources of wasted energy. In many cases, significant energy savings can be made by systematically applying existing technology to reduce pump energy consumption. This paper reviews available pump energy saving methods and presents application guidelines for both new pumping designs and retrofit into existing installations. Detailed examples are given for each of the twenty pump energy savings techniques that are discussed.
