FIELD: oil and gas production, particularly full low-pressure gas trapping (collecting) and gas losses prevention during hydrocarbon production and refinery.
SUBSTANCE: method for gas trapping with the use of ejector involves pumping working fluid under 2.3-9.5 MPa via ejector; mixing working fluid with low-pressure gas along with provision of hydrocarbon content in components to be mixed of at least 10% of component volumes; increasing pressure in flow-through ejector section and pipeline downstream the ejector; providing low-pressure gas compression up to 0.3-6.5MPa; moving water-and-gas mixture in separator to separate working fluid from gas; supplying gas with necessary transport pressure to main line; returning working fluid in ejector.
EFFECT: increased efficiency due to decreased time and costs of gas delivery to point of destination.
