Description

The invention relates to devices for the separation of immiscible liquids and can be used in the gas, oil, oil refining and chemical industries, for example, in low-temperature separation, condensation and rectification of natural and petroleum gas,

The purpose of the invention is to increase productivity by reducing hydraulic resistance, as well as simplifying the design.

The phase separator liquid mixture contains the housing 1 with the inlet nozzles

mixture 2, gas outlet 3, light liquid exit 4, heavy liquid exit 5. Inside transverse housing 1 are installed transverse supporting b and 7 partitions with rows of holes in which, for example, tubular coalescing cartridges 8 are fixed. Phase 9 and heavy phase 10 of coalescing cartridges 8 along the interphase level are installed separator plates 11 and 12. In the second embodiment, the separator plates 12 are twisted through 180 ° and installed in a row starting from the second. The phase output node of the cartridges 8 is made in the form of a package of transverse shelves 13 installed horizontally in each row of coalescing cartridges 8, and on one side to the shelves 13 are rigid fixed with outlet ends separating plates 11 and 12, and on the other side of the shelf

13 attached to the edge of the longitudinal partition 14 installed in the settling zone 15 The shelves are interconnected in pairs at the ends and on the side of attachment to the longitudinal partition 14 by vertical plates 16 arranged in a checkerboard pattern relative to the longitudinal partition 14 with the formation of compartments 17 and 18 communicated with the inner cavity of coalescing cartridges 8. Longitudinal septum

14 can be installed obliquely relative to the shelves 13.

In the second version of the coalescence

The chucks 8, in which the separation plates 13 are installed, twisted through 180 °, are provided at the exit sections in front of the plates 12 with holes 19 for gas to escape.

Phase separator works as follows.

The mixture enters the housing 1 through nozzle 2, is distributed over the free section, while the gas is weathered from the mixture, accumulates in the upper part of the apparatus and is discharged through the nozzle 3 of the gas outlet. The liquid mixture enters the tubular coalescing cartridge 8, in which the mixture is separated into a light 9 and heavy 10 phase, light phase 9 occupies the space in the upper part of the cartridge 8, and the heavy 10 in the lower part. When the streams of the separated phases 9 and 10 exit the cartridges 8, the stream of light 9 and heavy 10 phases is separated by plates 11 and 12. In the second embodiment, plates 11 and 12, installed through a row, turn the streams so that hard phase 10 sent to the upper part of the cartridge 8 a e (ka 9 - in

the bottom, thereby reducing the number of shelves 13 and vertical plates 16. The evolved gas in the coalescing cartridge 8 is discharged through the holes 19. The separated phases from two adjacent rows 8 enter the compartments 17 and 18 formed by the shelves 13 connected together in pairs by vertical plates 16 From compartments 17 and 18, the light 9 and the hard 10 phases, delimited by the inclined partition 14, enter the settling zone 19, while the bulkhead 14 is inclined in such a way that the easy 9 phase is above it, and heavy 10 under it. In this way, the repeated mixing of the separated phases in the settling zone 15 is eliminated. From the settling zone 15, light phase 9 is led out through the pipe 4, and heavy 10 through the pipe 5

The execution of a node for organized extraction of separated phases from coalescing cartridges in the form of compartments formed by horizontal shelves with vertical plates communicated with their internal cavity provides separate output of phases from coalescing cartridges without reducing their flow area. Calculations show that, depending on the ratio of the light and heavy phases in the initial mixture, the outlet section of the cartridges at the output increases by 15-20%. Since the productivity of the apparatus depends directly on the flow area of the cartridges, the productivity also increases accordingly.

Thus, the use of the invention allows to eliminate the existing technical contradiction: to eliminate the repeated mixing, without increasing the hydraulic resistance, and, therefore, without reducing the productivity of the apparatus, i.e., retaining its useful property, to eliminate the harmful
