Description

The invention relates to the oil and petrochemical industry, in particular to the preparation of oil for processing. A known installation for the preparation of trap oil includes a heat exchanger, a sump and a pump. The trap emulsion from the tanks of the purification vessels is taken in by a pump, to the reception of which the reagent is dosed in the amount of 160-180 g / t and is fed through a heat exchanger into the sump. After the sump, a trap emulsion with a water content of 7-10% in small doses is pumped into commercial oil 1. The drawbacks of the installation are the high consumption of reagent, the low degree of destruction of trap oil, and the fact that circulation and accumulation of gravitational stabilizer occurs in the installation, worsening the quality of the prepared oil. The known oil separation unit includes a pond, a pump, a contactor, a reservoir, a buffer tank, a furnace for burning sludge. The trap oil is pumped from the storage pond and sent to the contactor where the steam is supplied. In the sump, the separation of catch-up oil occurs. The slurry after the buffer tank is directed to incineration of C2 3. However, in a known installation, the separation efficiency of trap oil is low. The presence of a storage pond leads to an additional increase in the stability of the emulsion, pollution of the atmosphere. The closest to the invention is a treatment plant for a trap, including a two-product hydrocyclone, a pump, a separation tank 3. The installation has the following drawbacks: low degree of destruction of B5 oil, the filter requires frequent cleaning and replacement, and the oil after the separation tank must be further processed The purpose of the invention is to increase the efficiency of the destruction of trap oil. The goal is achieved in that the installation for treating trap oil, including a two-product hydrocyclone, a pump, a separating tank, is equipped with a three-product hydro cyclone, supplying the nozzle of a three-product hydrocyclone is connected to the discharge hole of the two-product hydrocyclone, and the discharge nozzle of the hydrocyclone is connected to the separation tank to get the object. a fresh water supply unit and an acoustic coalescence device, the separation tank being bzhen supply conduit otdelivsheys therein Vod input two-product hydrocyclone. FIG. 1 is a schematic diagram of the proposed plant for treating trap oil; 2 shows the structure of an acoustic coalescence device. The installation includes a two-product hydrocyclone 1, the discharge opening of which is connected through pump 2 to a three-product hydrocyclone 3. The drain pipes of hydrocyclones are connected to the separation, reservoir 4, pipeline 5, having a dismulgator dispenser b, fresh water supply unit 7 ,. device for acoustic coalescence 3. Device 8 (FIG. 2) includes a supply pipe .9, plugged at one end and having openings 10 on the side surface for the passage of fluid. Inside the inlet pipe 11, a rotor 12 is installed, also having a hole in the side surface. Outside the pipe 9 opposite the holes 10 are made 13 with a discharge pipe. When the rotor 12 rotates, the holes 10 on the rotor 12 and the pipe 9 align and overlap. As a result, due to the interruption of the fluid flow, acoustic oscillations are generated in the inner cavity of the rotor 12 and chamber 13. At the same time, the device is designed in such a way that mass transfer and crushing processes take place in the inlet pipe 9 and the rotor cavity 12, and the cavity of the chamber 13 is enlarged in the droplets, i.e. coalescence drops. The installation works as follows. Lubricant oil from oil treatment plants is received at the reception of a two-product hydrocyclone 1, in which the oil is separated from water and mechanical impurities. The water with mechanical impurities is separated from the pump 2 by the pump 2 with a three-product hydrocyclone 3, in which there is an additional separation of oil from the water, water is purified from mechanical impurities and sent further to the pumping stations (KNS) for injection into the reservoir. The slurry is sent for disposal. Oil separated in hydrocyclones 1 and 3 is sent for further processing. B oil is sequentially injected with a demulsifier dispenser 6 to destroy the emulsions, fresh water is supplied from the unit 7 for leaching of salts. To increase the efficiency of times. crushing the emulsion and leaching of salts; device 8 is intended in which;

The action of acoustic vibrations intensifies the processes of mass transfer, crushing and coalescence of water droplets. The frequency and intensity of acoustic oscillations are selected depending on the stability of the trap oil. After processing in the device 8, the oil enters the separation tank 4, in which the separation of oil from water occurs. The water separated in tank 4, containing the demulsifier, is pumped by pump 2 to receive a two-product hydrocyclone i, thereby increasing the process.

break trap oil (not shown).

The application of the proposed treatment plant for trap oil, in which the oil is preliminarily separated in hydrocyclones from water and mechanical impurities, and then subjected to further processing by introducing a demulsifier, fresh water, into the acoustic field, allows the treatment of trap oil reduce the cost of its preparation, improve the quality of commercial oil.
