GAS EJECTOR Russian patent published in 2010 - IPC F04F5/18 

FIELD: machine building.

SUBSTANCE: ejector is designed for gas and gas condensate field preparing at assemblies of low temperature gas separation with ejectors for gas utilisation and degassing of condensate. The gas ejector consists of a case with branches for high pressure, low pressure and mixed flow of gas. It also consists of a nozzle and of a mixing chamber coaxially arranged in the case; a bushing of a diffuser adjoins the mixing chamber. Also the branch of low pressure gas is conjugated with the mixing chamber via a narrowing circular cavity. An output section of the cavity of low pressure gas is of a toroid shape. A start section of the chamber wall has a circular thermo-insulating interlayer. Position of the mixing chamber in the case is fixed by means of the diffuser bushing adjacent to a collar of the case.

EFFECT: reduced metal consumption for fabrication of gas ejector and increased reliability of operation under modes of hydrate formation.
