Abstract

Mechanical methods for reducing drastically the energy consumption of high pressure liquid pumping and for eliminating the use of expensive multi-tube heat exchangers. The basic method is to utilize high pressure vapor at the suction side of the pump to reduce the required pumping pressure head. The energy content of the high pressure vapor is returned or utilized. Additional methods are provided to reduce energy requirement for transferring liquid to vapor generator, apparatus located at high elevation and apparatus having high pressure resistance.
