Description

The invention relates to devices for the separation of oil and gas emulsions and can be used in the oil and oil refining industries.

A known unit for the preparation of oil, including a horizontal technological tank, divided by transverse overflow partitions into sections for preliminary oil refining in a heating chamber with heat pipes and deep cleaning in a sludge chamber with a coalescing unit, an oil-gas-water emulsion inlet and an oil and water gas inlet device. (see utility model of the Russian Federation No. 31388, MPK7 B 01 D 17/04, app. 02.04.2003, op. 08.10.2003)

The closest in technical essence and the achieved result to the claimed object is an oil treatment unit containing a horizontal technological tank divided by transverse partitions into sections for preliminary gas separation, preliminary dehydration with a hot water supply unit, deep dehydration and end separation, distributors supplying an emulsion stream under water jacket, gas heater under the water cushion in the preliminary gas separation section, coalescing filter and measuring, control and automation equipment. (see invention of the USSR No. 352928, MKI C 10 G 33/00, c. August 31, 1970, op. September 29, 72, prototype).

The disadvantage of analogue and prototype is the lack of regulation of the level of the phase boundary in the sections of the installation.

The task underlying the utility model is to create a reliable and easy-to-use installation that provides control of the phase separation levels in each section of the technological process, which leads to an increase in oil quality at minimal cost.

The technical result is achieved by the fact that in the installation of oil preparation, which includes a horizontal technological tank, divided by transverse partitions into sections for preliminary and deep oil refining, input devices for emulsion and output of separated phases, as well as measuring, control and regulation means, the tank is equipped with a water collection section, separated by a transverse partition from the last in the technological chain of the deep oil refining section. Pipes mounted in the lower parts of the partitions are located in the water collection section, so that each pipe is in communication with one section, and their free ends are equipped with phase level controllers. The regulator of the level of the phase separation can be made in the form of a sleeve installed in the pipe, connected by means of a screw to a plate fixed in the tank fitting.

An oil treatment unit can have both vertical and horizontal design of tanks.

The essence of the utility model is illustrated by the example of the installation of oil treatment with a horizontally located technological capacity.

Figure 1 shows a General view of the installation in section, figure 2 - section aa in figure 1, the regulator of the level of the phase separation, figure 3 - section bb, mounting the regulator in the tank fitting.

The oil preparation unit contains a horizontal cylindrical tank 1, divided by transverse blind blind walls 2 and 3 below, into successively arranged sections for preliminary oil refining 4, deep oil refining 5 and collection

water 6. In section 4 of the oil pre-treatment, a horizontally oriented U-shaped heat pipe 7 is installed, equipped with a burner 8 and a chimney 9. In section 5 of the deep oil treatment, a coalizing block 10 is placed, and in section 6 of collecting water from the previous compartments, two parallel overflow pipelines 11 and 12, the ends of which are welded into the lower parts of the corresponding partitions 2 and 3. At the other ends of the pipelines 11 and 12, level controllers for the phase separation 13 and 14 are installed, which are installed in the pipes by means of grease devices 15 sleeves 16, connected by screws 17 with plates 18, which are fixed in the fittings 19 of the tank 1 with fasteners 20. The tank 1 is equipped with a water level regulator 21, an interphase level regulator 22, an emulsion inlet fitting 23, oil outlet pipes 24, gas 25 and water 26, connected by a system of pipelines and associated with means of measurement, control and regulation of the installation (not shown in the drawing).

Installation works as follows.

Oil-gas-water emulsion through the nozzle 23 enters the pre-treatment section 4 and, moving along the flame tube 7, heats up. In the process of heating, the emulsion is destroyed and intensive formation water is deposited, which is discharged through the nozzle 26. The destroyed emulsion through the transverse baffle 2 enters the deep cleaning compartment 5, where, passing through the coalescing block 10, it is finally separated into oil and water. In section 4, the level controller 21 maintains the water level below the flame tubes 7 by continuously discharging it through the nozzle 26. From section 5, oil and water are discharged through the nozzles 24 and 26, respectively, and the regulator 22 maintains a certain interphase level. The regulation of the water-oil phase separation in sections 4 and 5 is performed by turning the screw 17 of the corresponding controller. Gas is discharged through the pipe 25,

gathering in the upper part of the tank 1, part of which can be fed to the burner 8 of the flame tube 7.
