Description

I

The invention relates to a technique for the separation of water-oil emulsions in an electric field and can be used in the dehydration and salinization of oil in oil fields and petrochemical plants.

 The purpose of the invention is to increase the efficiency of the dehydration process,

FIG. 1 is a diagram of the proposed electric dehydrator in FIG. 2 - section A-A in FIG. one.

The electrodehydrator contains a capacitance 1, inside of which there are rows of pin vertical electrodes 2 and 3 of different polarity arranged in a checkerboard pattern. Electrodes 2 are fixed in the grid 4, suspended on insulators 5 inside the tank, and electrodes 3 are fixed in the grid. 6 ,. A tank installed at the bottom 1. The grids 4 and 6 are connected to different poles of the high voltage source 7, Capacitance 1 is equipped with vertical corrugated dielectric plates 8, in which the pin electrodes 2 and 3 are located, along the two 1SHMI corrugated plates are mixed; electrodes of one polarity are inserted. Capacity 1 is equipped with a branch pipe 9

yes emulsions and on-line 10 and 11 of the drainage of dehydrated liquid and water, respectively,

The electrodehydrator works in a stable manner.

The emulsion entering the container through the pipe 9, passes through an electric field - created between electrodes 2 and 3. Power lines

10 the floor is shown in FIG. 2 dotted line. When passing through the field, the globules of water are enlarged and deposited on the bottom of the tank 1. - The dehydrated liquid is discharged through the nozzle 10, and the accumulated - .15 s at the bottom of the tank 1; water is discharged into the drainage through the nozzle 11. During the electroprocessing of the emulsion, chain structures are formed between the electrodes of different polarity

20 however, due to the presence of a dielectric plate 8 between each pair of adjacent electrodes 2 and 3, this structure does not lead to a short circuit of the electrodes with water.

25 chains. In this case, even if the surface of the plates 8 is contaminated with a film of water or particles of electrically conducting impurities, the electric field does not disappear in the - 30 emulsion volume.
