YOUR DEVICE IS PRECONFIGURED SEPARATION AND FILTRATION Russian patent published in 2016 - IPC B01D19/00 E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: preliminary separation device comprises filtering and piping connections for inlet and outlet of the gas-liquid mixture of liquid and gas, as well as partitions. Vertical conduit formed in the center is situated an inlet for supplying a mixture to which is attached an inclined pipe, wherein the pipe axis an angle of 30°. Pipeline is divided by partitions into the chamber opposite the nozzle for feeding a mixture of primary separation chamber is bounded by the partitions with holes in the center, is located above the upper wall of the filtering chamber, and a bottom wall is a secondary separation chamber. Before fitting the primary separation chamber in a centrifugal separator installed in a spiral, with closed ends. On top of the second baffle is attached a centrifugal separator in a spiral with open lower end, wherein the second separator to a hole in the pipeline, which is connected with the pipe duct mounted above the groove with a filter arranged on the side surface of the inclined pipe length. Before opening the second separator is fixed deflector separators placed between the second deflector on the lower partition installed swirl spiral type, and above it - a conical confuser. In the nozzle for supplying a mixture of adapter is configured as a truncated irregular prism. In a secondary separation chamber to partition a reflector configured as a crescent-shaped blade fastened between the flat conical ring and disc, and between it and the spout is located defoamer. Filtration chamber before the tube for withdrawing gas separator is a gas with crescent blades, and a filter septum disposed in the conical deflector, wherein in the partitions are made drain holes, which are inserted in the tube length goes beyond the separator, or convergent channel.

EFFECT: technical result of the invention is to increase the separation efficiency gas-water-oil mixture with high gas content while reducing the size design.
