Abstract:
An operational process for a pumping-ejector unit, comprising the steps of:feeding a liquid motive medium from a separator into at least one nozzle of a liquid-gas ejector by a pump;evacuating a gaseous medium by at least one jet of the liquid motive medium;forming a gas-liquid flow in the liquid-gas ejector and simultaneously compressing the gaseous medium;feeding the gas-liquid flow from the liquid-gas ejector into a hydrodynamic device for adjusting flow speed, including decelerating the gas-liquid flow in the hydrodynamic device to a subsonic speed by controllably enlarging a flow-through canal defined by the hydrodynamic device and expanding the gas-liquid medium in the hydrodynamic device; andfeeding the decelerated gas-liquid flow into the separator, where a compressed gas is separated from the liquid motive medium.
