Abstract

The invention relates to an oil dewatering apparatus and can be used to separate two immiscible liquids of different densities containing free gas. The purpose of the invention is to increase the efficiency of the apparatus by preventing the harmful effect of the released gas on the oil and water separation process. The oil dewatering apparatus consists of a tank 1, equipped with fittings for the input of emulsions 2 located on the lower generator of the tank, output of oil, output of water 4, and the oil-to-water level controller 5. Inside the tank is a box with partitions. Windows 8 and 9 are filled in the walls and partitions respectively. Windows 9 are located under the distributors. The lid of the box is filled with a rise from its side walls to the middle and has slopes from the end walls to the middle. In the end walls there are windows, adjacent to the bottom of the duct for removal of gas from under it. In the oil outlet, local resistance is established, made in the form of a conical sleeve, with the smaller base facing upwards. Above the bottom of the sleeve in the nozzle below the top of the forming capacity of the vessel are holes that provide, in conjunction with local resistance, gas is leaking into the oil outlet. 1 3.p. f-ly, 3 ill.

Description

This invention relates to an oil dewatering technique and can be used to separate liquids of various densities in the petroleum, petrochemical, and oil refining and other sectors.

The aim of the invention is to increase the efficiency of the apparatus by eliminating the influence of gas evolution on the process of oil dehydration.

FIG. the apparatus is presented, a general view in section; in Fig .. - node I in Fig.1; on fig.Z - section aa on fig.I

The apparatus for co-production of oil and water includes a tank 1 with fittings for entering the emulsion 2, located on the forming window, 1, its tank, fitting 3 for oil outlets 8, equipped with a perforated mother liquor, fittings 4 for outputting water and a level regulator 5. Inside the tank along its about si installed box 6 with partitions 7 mounted along its side walls inside the box. In the lower part of the walls of the box and partitions there are windows (respectively, 8 and 9). The windows 9 are located under the distributors 10. The cover 11 of the box is made to rise from its side walls to the middle and has slopes from the end walls 12 to the middle. In the end walls 12, 35 are cut-out; es)) the efficiency of the window 13, adjacent to the box cover. In the nozzle 3 output oil installed local resistance 14, made in the form of a conical sleeve, facing the smaller base upwards. Holes 15 are made in the walls of the fitting 3 under the upper forming container 1 above the edge of the larger base of the conical sleeve.

The apparatus, due to the following factors, eliminating the hydrodynamic effect of the evolved gas on the process of settling, which is achieved by removing gas through the holes in the bottom walls of the duct, mines the defending zone j eliminating the possibility of reducing the duct's working volume due to the accumulation of gas in it,

The device works as follows.

The emulsion through the nozzle 2 enters the duct 6 into the space between the partitions 7. As the emulsion moves to the windows 9, equidistant from the nozzles 2, free water is released from it, which is discharged from the apparatus through the nozzle 4. Then the emulsion enters the space through the windows 9 between the walls of the duct 6 and the partitions 7 and through the windows B in the side walls of the duct enters the distributors 10. Evenly distributed 27907 2

The device is limited in the device section through the side walls of the distributors. The emulsion enters the device volume. The emulsion is divided into oil and Boda. Water B between the windows 8 moves down the apparatus and B111 is brought together with the free water through fitting 4, Separated from the oil rises into

Q is the upper part of the apparatus and is outputted through the fitting 3. In the apparatus, the level of oil-water phase separation is maintained by the regulator 5.

Coming with an emulsion

15, gas is released under duct 6 and due to the slopes of the large duct of the engine; kets along its upper part to windows 13, through which gas is withdrawn and rises to the upper tank formation,

20 minutes of the settling zone (distributor system) Execution of the cover 11 of the box with a lift from its sides (mx walls to the middle and with slopes from the end walls to the middle reduces

25 the path of the gas and accelerates its withdrawal from under the box. The local resistance 14, made in the form of a conical sleeve, creates a pressure drop by the apparatus and the zone behind the sleeve, due to the fact that it is less than 1 / gas through the holes 15 evenly flows into the oil flow and is withdrawn with it from the apparatus. The use of the proposed apparatus in comparison with limes allows us to identify es}) the efficiency of work

the apparatus due to the following factors: elimination of the hydrodynamic effect of the evolved gas on the process of settling, which is achieved by removing gas through the holes in the end walls of the duct, mine the defending zone j eliminating the possibility of reducing the duct's working volume due to the accumulation of gas in it,

which is also achieved by its constant removal from under the box; the elimination of the possibility of a decrease in the working volume of the apparatus due to the accumulation of gas under the upper forming capacity,

what is achieved by a constant gas outlet through the holes in the oil outlet and the creation of a pressure skull by a conical sleeve; eliminating a decrease in the working volume of the apparatus

due to the formation of a stagnant zone under the upper image of the vessel, even under conditions when there is no gas evolution. In this case, in the area of the tank above the distributor to output oil

and its upper generates accumulated sediment. The holes and the tapered bushing in the nozzle ensure its permanent withdrawal from the apparatus.
