FORMATION GAS MIXTURE SEPARATION METHOD Russian patent published in 2024 - IPC F17D3/14 B01D3/00 F25J3/06 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to oil and gas industry and can be used in oil, gas and gas condensate fields for separation of mixtures of liquid and gas. Method includes three-stage separation of gas and liquid flow mixture with liquid separation, flow temperature reduction by means of heat exchangers, separation of liquid into condensate and water, degassing of condensate by means of buffer tank, removal of gas, condensate and water. Degassing of condensate is carried out in three stages, for which the buffer tank is divided along the length by means of two damping partitions into three sections. At the first stage, the mixture of formation gas and liquid is fed into the first section by means of a distributor to the bottom of the buffer tank and from above, using partitions, gas and liquid velocities in the second section are levelled, thus forming a stable surface of gas and liquid contact. Further, liquid flows are passed through the second damping partition and a block of damping nozzles mounted at the inlet of the third section, where final separation of gas, condensate and water from each other is carried out. Gas is removed from the tank by means of an ejector into the third separation stage.

EFFECT: high efficiency of separation and complete separation of components of the mixture from each other.
