Description

The invention relates to gravity separation and degassing apparatuses for unmixing liquids of various densities and can be used in field and factory installations for the preparation and processing of oil and gas.

The aim of the invention is to reduce the metal intensity of the apparatus.

Figure 1 shows a separator with a light fraction collection compartment, a general view, in FIG. 2, a separator with a light fraction collection pipe in the upper part of the compartment, general view; in FIG. 3, view A in FIG. 2; figure 4 - section bb in figure 2,

The separator of liquids contains a housing 1 with nozzles of the inlet mixture 2 and the outlet of the heavy fraction 3 and the light fraction 4. The housing is divided by a transverse partition 5 into compartments of sludge 6 and collecting the heavy fraction 7. The housing is equipped with a collection of 8 heavy fractions located in the lower part of the housing outside of it. Collection 8 communicates with the compartment 6 and through an overflow device made in the form of a pipe 9 and including a movable partition 10, with a collection of the heavy fraction 7. The upper end of the pipe 9 of the overflow device is fixed on the movable partition 10, the lower end of the trumpet

9 is placed in the collector of heavy fraction 8. The movable partition 10 is installed against the transverse partition 5, made with a groove 11, movable relative to the transverse partition 5. The separator is equipped with a mesh baffle 12, a drain fitting 13, a gas outlet 14, a manhole Lase 15. At the top of the collection compartment of the heavy fraction 7, a collection compartment of the light fraction 16 can be placed.

The separator works as follows.

The mixture through the nozzle 2 enters the compartment 6 of the gravitational separation, where, due to different densities, the gas-liquid mixture is separated and degassed under the action of the gravitational force. The separated light fraction is withdrawn from the apparatus through the nozzle 4, and the separation from the heavy fraction through the pipe 9 of the overflow device enters the compartment 7 and is removed from the apparatus through the nozzle 3. The weathering gas passes through the screen bump 12 and is discharged through the nozzle 14.

When the separator is working or the DAY splitter is used for other conditions, changes in the density and composition of the mixture are possible, which leads to a change in the position of the phase boundary. Making the overflow device moving along the transverse partition 5 up or down makes it possible to keep the level of separation of fractions constant and thereby keep the corresponding height of the zone of fractions apart.

This solution improves the separation efficiency when changing the density and composition of the mixture due to

maintaining a given interfacial level, the specific metal consumption of the apparatus decreases, its service life increases due to ease of maintenance during revision. and

accordingly, the product yield, the range (range) of use at different fields with different densities of liquids is expanded, the design of the apparatus is simplified, its dimensions are reduced.
