TUBE SEPARATION INSTALLATION Russian patent published in 2009 - IPC B01D19/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to equipment for oil producing industry, notably, to installations for separation water from products of oil wells. The installation consists of an inclined column and of pipelines connected to the column; the pipelines serve for supply of water-oil-gas mixture and for withdrawal of oil, water and gas. The pipeline for supply of mixture is connected to the column via the facility-damper made in form of a device for preliminary separation of water-oil-gas mixture equipped with branches of withdrawal of gas, water and oil, supplying, correspondingly, gas into the gas withdrawal pipeline, oil and water into the column. The outlet of the branch for drainage of water into the column is located above the outlet of the branch of oil supply into the column. The outlet of the branch of the water drainage is connected to an oil settling section of the column at the level of the upper level of fluid in the oil settling section. The inlet into the pipeline of oil withdrawal is situated at the level of the upper level of fluid in the oil settling section. The upper level of fluid in the oil settling section is maintained automatically, for example, by means of a hydro-measuring unit assembled on the pipeline of oil withdrawal. The outlet of the branch of oil supply is connected to the column at the level or below the lower level of oil in the column.

EFFECT: increased efficiency of installation.
