Abstract

The invention relates to an apparatus for separating a water-in-oil emulsion and can be used in oil treatment plants in oil fields and oil refineries. The aim of the invention is to increase the efficiency of the apparatus due to the intensive destruction of the emulsion jets into homogeneous small droplets. The apparatus includes a housing, electrodes, a collector for introducing an emulsion with distribution pipes 6 and baffle plates 7 attached to the distribution tubes 6 by an edge 8. The edges of the baffle plates are in the form of petals 9 alternately bent upwards at an angle of 90 & and obtuse angle to the plane of the baffle plate. On the collector pipes are holes in such a way that their axes intersect the baffle plate 7 in the place of the limb of the petals. 3 il. and

FIG. 2

The invention relates to apparatus for the separation of water-in-oil emulsions and can be applied to oil treatment plants in oil fields and oil refineries.

The purpose of the invention is to increase the efficiency of the apparatus.

FIG. 1 shows the apparatus, a general view; in fig. 2 — node I in FIG. one; in fig. 3 node II in FIG. 2

Lena oil is removed from the apparatus through the nozzle 3, and the water containing salts is drained from the apparatus through the nozzle 4. The smallest drops of water are enlarged in the electric field created in the apparatus by the electrodes 2.

The use of the invention allows for a reduction in the average diameter of droplets formed during jet disintegration, as well as a more uniform distribution

The apparatus for dewatering and desalting of crude oil in the area of the apparatus, since the oil injection includes a housing 1, electrodes running to the place of limb of the jet leaves 2, a fitting 3 for draining water, a fitting 4 for removing oil, a collector 5 for introducing an emulsion with distribution pipes 6 and the baffle plates 7 attached to the distribution pipes 6 by an edge 8. The edge of the baffle plate 7 is made in the form of petals 9, alternately bent upwards at an angle of 90 ° and obtuse with an angle to the plane of the baffle plate.

On the collector pipes b, the openings 10 are split, since the jet disintegrating does not take place in such a way that their axes are re-under the collector pipe, but in the area lying to the right and left of it.

Invention Formula The device works as follows. 25 The apparatus for dewatering and desalting-Water-oil on the emulsion enters the oil field, containing a cylindrical the manifold is over the manifold 5 and flows out of the bore-body, the inner tubular manifold with Step 10, located on the distributor, as a result of the interaction, disintegrates into droplets, pops up a wide front. in a layer of water. Thus, the apparatus for dewatering and desalting oil allows to improve the disintegration of the emulsion jet into droplets, as well as the distribution of the water-oil emulsion over the cross section due to an increase in the width of the rising front of the casing flap 7 at the bend of the petals. Tubes 6, in a layer of water, whose level is maintained above the horizontal axis of the collector 5. The emulsion jets hit the baffle plates 7 at the point where the petals are bent, are destroyed into uniform droplets that float up to the interface. Here an intermediate layer is formed in which the water droplets contained in the oil merge to form larger droplets that precipitate and the droplets of oil float. Dehydrated and dehydrated35 distribution pipes, in the lower part of which there are holes for entering the emulsion, and horizontal baffle plates located under the distribution tubes, characterized in that, in order to increase work efficiency, the edges of the baffle plates are made in the form of petals bent upwards alternately under the straight and blunt angle to the baffle plate, with the axis of the holes crossing the baffle plate in place of the limb of the petals. Lena oil is removed from the apparatus through the nozzle 3, and the water containing salts is drained from the apparatus through the nozzle 4. The smallest drops of water are enlarged in the electric field created in the apparatus by the electrodes 2. The use of the invention allows for a reduction in the average diameter of droplets formed during jet disintegration, as well as a more uniform distribution  oil in the area of the apparatus, since those who run into the place of the limb of the jet's petals oil in the area of the apparatus, since those who run into the place of the limb of the jet's petals pel, because the jet disintegrates not under the collector pipe, but in the region that lies as a result of the interaction, they disintegrate, droplets, pop up on the broad front in a layer of water. Thus, the apparatus for dewatering and desalting oil allows to improve the disintegration of the emulsion jet into droplets, as well as the distribution of the water-oil emulsion over the cross section due to an increase in the width of the rising front of the hull, the inner tubular reservoir five distribution pipes, in the lower part of which there are holes for entering the emulsion, and horizontal baffle plates located under the distribution tubes, characterized in that, in order to increase work efficiency, the edges of the baffle plates are made in the form of petals bent upwards alternately under the straight and blunt angle to the baffle plate, with the axis of the holes crossing the baffle plate in place of the limb of the petals.
