Description

The device relates to the oil and gas processing industry, in particular, to the field of installations for the collection and preparation of oil and gas fields, namely, to the degassing of oil and purification of associated gas.

A device for degassing oil and cleaning associated gas [see Planovsky A.N. Processes and devices of chemical technology: - M .: Chemistry, 1989. 848 p.]. The oil and gas separator contains a housing with openings for entry and exit of products, a droplet eliminator, inclined shelves and a heating element.

The disadvantage of this separator is the poor quality of oil degassing.

The closest known solution is a gas-liquid separator [see A.S. USSR No. 819312, 04/07/81.], Comprising a housing with holes, a variable pitch screw, adapters, and a guide sleeve.

However, the disadvantage of this separator is to reduce the quality of cleaning the gas stream from the liquid and insufficient dust suppression.

The technical task is the creation of an oil and gas separator, which allows to increase the degree of purification of the oil and gas stream from gas, sludge and liquid.

The technical result is an increase in the separation area.

It is achieved by the fact that a continuous screw shelf with guides and protrusions is introduced into the Oil and Gas Separator. This method shows that the separation area is 9% larger, which leads to a corresponding increase in the quality of separation. The separation area of the oil and gas separator with inclined shelves is calculated by the formula

where: r is the inner radius of the separator, α is the angle of inclination of the shelf, n is the number of shelves. The separation area of the oil and gas separator with a solid helical shelf is calculated by the formula

where: b is the step of the turn, k is the number of steps, r _mp is the radius of the pipe. On the surface of a continuous helical shelf there are guides that help the product spread over the entire surface. The protrusions swirl the gas-liquid flow.

The proposed device is shown in Figure 1. It contains a housing 1 with a pipe for inlet 2 and oil 3, a pipe for gas 4, a pipe for water 5, a pipe for sludge 6, a louvre droplet eliminator 7, a solid screw shelf 8, with guides 10 and protrusions 11, and the heating element 9.

In the housing 1 there is a continuous screw shelf 8, with guides 10 and protrusions 11, above which an inlet pipe for oil 2 is located. A louvre droplet eliminator 7, a pipe for the exit of gas 4 and water 5 are vertically located, forming a separate compartment. At the bottom of the body there is a pipe for the exit of sludge 6, over which a heating element 9 is located. A pipe for the exit of oil 3 is located below the oil level.

The device operates as follows: the oil flow penetrates through the pipe 2, reaches a continuous screw flange 8, gradually merging, is divided into gaseous and liquid phases. The gas phase, as lighter, disappears upward. There it passes through the louvre droplet eliminator 7 and enters the nozzle for the exit of gas 4. Liquid droplets merge from the droplet eliminator and exit through the nozzle 5. The merged oil at the bottom of the separator is heated by the combustion device 9 and settles. The pure product exits through the pipe 3, and the slag is removed from the separator through the drain pipe for the sludge 6.

The positive effect is that a solid screw shelf with guides and protrusions increases the separation area, the guides help the product spread over the entire surface, the protrusions swirl the gas-liquid flow, which as a result improves the quality of separation.
