EJECTOR PLANT Russian patent published in 2022 - IPC F04F5/14 F25J3/00 

FIELD: ejector plants.

SUBSTANCE: invention relates to ejector plants designed to compress low-pressure gases due to the energy of high-pressure gases and can be used in the oil and gas industry. The ejector unit includes a main ejector, consisting of a high-pressure gas inlet pipe and a high-pressure gas supply chamber, a high-pressure gas nozzle, a low-pressure gas supply pipe, a low-pressure gas supply chamber, a low-pressure gas nozzle, a mixing chamber, a diffuser and a gas mixture sampling chamber. In front of the high-pressure gas supply chamber, inside the high-pressure gas inlet pipe, a swirler and a gas-liquid flow selection section are installed in series and axially, which is connected by a channel to the gas mixture selection chamber. The high-pressure gas supply chamber, the low-pressure gas supply chamber and the gas mixture extraction chamber are connected by pipelines to the respective chambers of at least two additional ejectors. Shut-off and control valves are installed in the pipelines.

EFFECT: invention makes it possible to increase the efficiency of the low-pressure gas ejection process and the reliability of the ejector installation in the presence of a liquid fraction in the high-pressure gas.
