Description

(54) LEEMULSATOR

one

The invention relates to devices for dewatering and desalting) and can be applied in the petrochemical industry.

A device for vefti dewatering is known, containing a vertical bar, in which conical and flat plates are located one above the other.

The disadvantage of the device is the disruption of the process on the quality of the dehydrated oil of the silting of the plates.

The closest in technical essence and the achieved result is a demulsifier, which includes a housing with inlet and outlet nozzles, inside which a partition is placed in the form of inverse truncated cones, coaxially arranged with which are plates.

The disadvantage of the demulsifier is the reliability of the oil dehydration process due to the uncontrolled change in the orifice cross section, due to the deposition of inorganic salts and corrosion products, as well as due to the growth of flat horizontal partitions.

The purpose of the invention is the prevention of silting up the demulsifier and increasing its productivity.

This is achieved by the fact that the demulsifier is equipped with grooves along the forming truncated cones, installed above the holes, and the conical plates are arranged with their lengths upwards.

FIG. 1 shows the described demulsifier, section; in fig. 2 is a section A-A of FIG. one; in fig. 3 - the element of a truncated cone with a hole.

The demulsifier contains a vertical housing 1 with pipes 2 and 3 of the input of water and emulsion, pipes 4 and 5 of the output of oil and water. Inside the body there are transverse partitions in the form of reverse truncated cones 6 with openings 7. Gutters 8 are installed above the openings, communicating with the cavities of the conical plates 9. The latter are at the same time pointing upward. The cone 1 is equipped with a pipe 1 output sludge Y.

The demulsifier works as follows. In the housing 1 through the pipe 3 enters-

with emulsion, and through the pipe 2 - rinsing in water. The phase separation level is maintained in the area of the upper conical plate. The emulsion collects under the partitions 3 and through the holes 7 formed along the truncated cones along the grooves 8 under the action of hydrostatic pressure flows under the conical plates 9. Next, the emulsion enters the next partition 6. This causes the emulsion to come in contact and shift with the flow of the wash water partitions eliminate stagnant zones in the apparatus, and repeated washing of the emulsion with water intensifies the dehydration of oil. Mechanical inclusions that fall out when the emulsion breaks down are deposited on the inner surface of the truncated cones, slide to the central hole, and ultimately accumulate in the lower part of the apparatus, from which sludge is discharged through patrice 10. The dehydrated oil is removed

through pipe 4, and water is discharged through pipe 5..

The proposed demulsifier eliminates the need for labor-intensive stripping, increases the productivity of the apparatus and preserves it for the entire period of industrial operation.
