Abstract

SUMMARY OF THE INVENTION: The apparatus includes a container with a layer of oil, prom. a daily layer and a layer of water, inlet and outlet pipes, a device for collecting and removing the intermediate layer. The device is made in the form of two partitions consisting of sections, on the axes of which are located dampers with counterweights. The apparatus has the ability to move relative to the articulated support from a horizontal position to an inclined one using a hydraulic support-hoist. 2 il.-

Description

The invention relates to the field of joint preparation of oil and water in satellite fields and can be used in the oil industry. 0 The aim of the invention is to increase the efficiency of oil and water preparation.

 In Fig. 1, the apparatus is shown in a horizontal position; figure 2 - in inclined. The apparatus comprises a container 1 with a layer of oil, water and an intermediate layer, an inlet pipe 2, an outlet pipe 3 for water, an outlet pipe 4 for oil, a device 5 for collecting and removing the intermediate layer. The device 5 is made in the form of two partitions 6 attached to the walls of the tank 1 obliquely to form a chamber 7. The partitions 6 are made of sections 8 installed at a distance of 9 from each other. Each section 3 is equipped

the axis 10, the counterweight 11 and the shutter 12. The device has a hydraulic support-lift 13 to the purge device 14.

The apparatus for the joint preparation of oil and water works as follows.

Water-oil is preheated - for emulsions with a reagent-demulsifier introduced into it, it enters through a pipe 2 into the lower part of the tank 1 under a layer of produced water, in which free water is separated from oil. Oil under the influence of gravitational forces moves upward, passing through the partitions 6, occupies the upper part of the tank 1 and is removed from it through the pipe 4, and the separated water is located in the lower part of the tank 1 and is continuously discharged through the pipe 3. An intermediate layer (non-destroyed) is formed over time water-oil emulsion), which interferes with the effective operation of the apparatus, is evenly distributed over

oil-water interface. Since the apparatus is in a horizontal position, the thickness of the intermediate layer is small, but even at this thickness the process of separation of oil and water is disturbed.

In order to concentrate the intermediate layer between the partitions 6 by means of a hydraulic lifting support 13, one end of the container 1 is torn off from the foundation support, and the other end of the container 1 is rotated relative to the hinge support. During the lifting of the apparatus, an increase in the thickness of the intermediate layer between the partitions occurs. When the slotted partitions occupy a horizontal position, the shutters 12 located on the axes 10, with the aid of counterweights 11, overlap the intermediate layer located between the partitions 6 (see figure 2) .; and after blowing the intermediate layer through the device 14, the device using the hydraulic (lifting support 13) again returns to the horizontal position, the shutters 12 located on the axes 10, using the counterweights 11 again open and the device operates in the specified mode.:.

Since the purge time is short, the process of oil and water preparation is not disturbed, and the efficiency of oil and water preparation increases, since when purging
