Pipeline Characteristics and Economic Consideration of Electric Pump Drives

Important hydraulic characteristics of liquid pipelines and pumps that are necessary to assist the power engineer in evaluating optimum drive characteristics are reviewed. Typical pipeline pumping stations are developed with characteristic curves at each station for different grades of crude oil. Engineering and economic evaluations are made for various station configurations including constant-speed pumps with throttling, multiunit pump stations, and adjustable-speed drive pumps.
