GAS SEPARATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC B01D45/04 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to gas, gas-processing, chemical, oil industry and can be used in processes and devices for separation of liquid and mechanical impurity from gas flow. The method of separation of gas comprises the supply of mix through a branch pipe of the device at a rate of 10 m/s minimum with the unidirectional transfer of the mix into open volumetric inertial gas-distributing device, supply of liquid drops and mechanical impurity with a part of gas into channels for extraction of liquid and impurity with radial extraction of previously separated gas from the volume inertial gas-distributing device towards the direction opposite to the flow supplied into it with subsequent gas supply to the following separation section. The gas-liquid flow rate is decreased repeatedly. At first the gas-liquid flow is directed from the one-flow input of mix to radial multi-flow with simultaneous separation of liquid with impurity. Then the flow is directed to a rope porous headpiece where it is oscillated, meanwhile the liquid is selected by cords, and then centrifugal separation is performed or centrifugal mass exchange with liquid which is separated simultaneously after that it is separated by means of passing through headpieces with diagonally corrugated surfaces, then through nozzles with diagonally located ledges. The gas separation device comprises the housing with branch pipes for mix input, output of separated phases and separation sections located in the housing and the volumetric inertial gas-distributing device. The volumetric inertial gas-distributing device is designed as a punched wedge-shaped housing with channels for passing of the separated mix with open base and top where the open base of the wedge-shaped housing forms with the mix input branch pipe the passes for recirculation gases, and the open top of the wedge-shaped housing is fixed in the drainage channel. The following is series installed between branch pipes of the gas-liquid mix inlet and the drained gas outlet - the volumetric inertial gas-distributing device, the rope porous headpiece fixed rigidly on the ends of the volume inertial gas-distributing device, the dish-shaped section of centrifugal separation or mass exchange with simultaneous separation, diagonally corrugated headpiece sections and/or sections made of sheets with fine-structured ledges with effective cross-sections for passing of gas-liquid flow widened from the first section to the last section.

EFFECT: creation of effective method and device for gas separation without filtering coalescing cartridges with self-cleaning of the preliminary separation system.
