High efficiency fluid separation device

摘要

A gun barrel tank for treating raw crude oil mixtures. The fluid mixture enters through a degassing boot where gas is separated from the liquid. The liquid travels through a central column to a horizontal hydraulic distributor located in the lower area of the tank, first entering a central distributor trough, then passing into open bottom horizontal inverted lateral troughs and finally out through a plurality of metering orifices provided near the top edges of the lateral troughs to provide uniform distribution of the liquid in the tank. A circular oil collection trough provided at the top of the tank has a plurality of V-shaped notches on its top edge over which oil flows into an oil collection trough to provided uniform collection of the separated crude. A circular water collector in the bottom of the tank removes separated water, and solids are removed from the bottom of the tank.

主权项

1. A fluid separation system, comprising:
an oil separation tank defining an inlet that is fluidly connectable with a tank interior, the tank interior having a top portion, a middle portion and a bottom portion arranged along a tank longitudinal direction; a gas separation device disposed between the inlet of the tank and a source of crude oil mixtures; a central column defining a fluid conduit, the central column being fluidly connected to the inlet of the tank and extending into the tank interior across the top and middle portions, the central column having at least one distributor opening disposed along the central column in the middle portion of the oil separation tank; a horizontal hydraulic distributor connected to the central column and being fluidly open with the distributor opening, the horizontal hydraulic distributor extending substantially along an entire cross section of the oil separation tank along a plane that is perpendicular to the longitudinal direction of the tank, the horizontal hydraulic distributor comprising at least one lateral trough defined by walls disposed on three sides of a channel, an open side oriented in a downward direction, and an end wall, the walls forming a plurality of metering orifices therein that fluidly connect the interior of the oil separation tank with the fluid conduit of the central column through the distributor opening and the channel; an oil collection trough disposed in the top portion of the tank interior and extending along a periphery of the oil separation tank along a plane that is perpendicular to the longitudinal direction of the tank; and a water collection manifold disposed in the interior of the tank at the bottom portion of the tank; and a gas equalizing line fluidly connecting the gas separation device and the top portion of the tank interior: wherein, during operation, a flow of crude oil mixtures provided by the source passes, in sequence, through the gas separation device, the inlet, the conduit defined in the central column, the distributor opening, the channel and the metering orifices to enter the tank interior.
