Description

The invention relates to the separation of gas from liquid and water from oil during the achievement and preparation of oil and gas and to be used in industries where the phase separation process takes place. "

The purpose of the invention is to increase the productivity and quality of separation,

FIG. 1 shows schematically an apparatus for implementing the proposed method; in fig. 2 is a section A-A in FIG. 1.

The device works as follows.

The production of wells through the inlet nozzles 2 and 3, separately in phases, is introduced into the first section, in which the process of gas separation from the liquid is accelerated with the help of vibrating devices 5. In this section there is an intensive release of large gas bubbles. The foam formed in each section is transported by a fluid flow and accumulates around the partitions 4. The process of destruction of the foam is carried out in water.

The device contains a capacitance 1 with the vibration effect

tube 2 for liquid inlet and choke 3 for gas inlet. Introducing trenn. Part of the tank is divided into sections by partitions 4, which are inclined against the flow of the liquid. Vibrating devices 5, for example plates, which are fixed above their center, are installed vertically along the separator in front of the partitions. This is caused by oscillating movement of the rods 6 of the gas-shakers 7 attached to the separator by means of fittings 8. The partitions 4 have openings 9 in the lower and upper parts. Inside the apparatus is a drip drop 10, which is mounted in front of the nozzle 11 for the gas to exit. There is a nozzle 12 on the container for liquid to exit. The intensification of the process of separation of gas from a liquid in each section occurs as a result of the fact that the vibratory stimulation of the plates from the plates, driven by the movement of the gas-sprays, and their frequency of oscillations from the chamber to the chamber increases, occurs on the liquid.

their shape and movement inside the fluid, which leads to coalescence and an increase in the velocity of their surface-45 Wu. After climbing to the surface, the foam forms a foam, which collapses under the action of vibration forces. The destruction of the foam is also carried out by the flow of liquid, noTOMj, that it is transferred by the liquid to the partitions, where the liquid changes direction and moves down along the partition 4. In this case, the foam is captured, which deforms and coalesces. 55 As a result, its quenching process takes place. Foam damping near partitions takes place at an angle of inclination of 30-60.

using vibrating devices and the energy of a fluid flow. Due to the fact that the vibrating devices 5 are located in front of the partitions 4, the foam first collapses around the vibrating devices as a result of the vibration forces. The remaining foam flows to the partitions 4, near which it is destroyed, as the liquid along the partition 4 goes down and, pressing the foam against the partition, deforms it and leads to coalescence. From the first section, the liquid passes to the second, where the vibrating device oscillates with a greater frequency than in the first section. In the second section, smaller gas bubbles are separated, which did not stand out in the first section, the foam formed in the second section is destroyed and transferred from the first one. In the next sections, where the oscillation frequency of the vibrating devices from section to section increases, the further release of smaller gas bubbles and foam occurs. In the last section, where the vibratory device oscillates with a maximum frequency, the phase separation process is completed. The gas through the drip trap 10 is directed to the fitting 11, and the liquid is separated through the fitting 12 to the consumer.
