SYSTEM FOR SEPARATION OF WATER, OIL AND GAS MIXTURE Russian patent published in 2016 - IPC B01D53/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry, in particular, to separation of water, oil and gas mixture, and aims to increase degree of utilisation of associated gas. System for separation of water, oil and gas mixture includes raw material supply pipeline connected to a unit for separation of feed stock with removal of water-oil emulsion, and includes at least two separation stages, each of which has an inlet for feed stock and branches of associated petroleum gas, connected with gas separator having an outlet for gas to consumer. System further includes a jet device for flow separation, located at inlet of feed stock supply pipeline, in form of confuser-diffuser junction, having a Venturi profile with two ejection slits: one - in contraction zone, which is interconnected with inlet pipe to feed medium-pressure gas, connected with outlet of associated petroleum gas of second separation stage, other - on edge of diffuser, which is interconnected with inlet pipe of low pressure gas supply pipe, connected with outlet of associated petroleum gas of end separation stage, wherein in order to remove associated petroleum gas of second and end separation stages, intermediate gas separators are installed.

EFFECT: invention provides stable, reliable operation of water, oil and gas mixture separation system with minimum volumes of low pressure separation gas and maximum output of light hydrocarbon fractions in output stream of commercial oil.
