Abstract:
An operating process of a pump-ejector-separator system, comprisingdelivering a motive liquid into a liquid inlet of a first-stage liquid-gas ejector and a second-stage liquid-gas ejector by a pump; evacuating a gaseous medium by the first-stage liquid-gas ejector; compressing the gaseous medium in the first-stage liquid-gas ejector; discharging a gas-liquid mixture containing the evacuated gaseous medium from the first-stage liquid-gas ejector into a first-stage separator; separating the gas-liquid mixture in the first-stage separator into a compressed gas and the motive liquid; evacuating the compressed gas from the first-stage separator by the second-stage liquid-gas ejector; additionally compressing the evacuated compressed gas in the second-stage liquid-gas ejector; discharging a second gas-liquid mixture containing the additionally compressed gas from the second-stage liquid-gas ejector into a second-stage separator; separating the second gas-liquid mixture in the second-stage separator into the additionally compressed gas and the motive liquid; subsequently delivering the additionally compressed gas from the second-stage separator to consumers; bypassing the motive liquid from the second-stage separator directly into the first-stage separator; and subsequently delivering the motive liquid from the first-stage separator to the suction port of the pump.
