Crude oil separation system

Abstract

The invention relates to an anti-overflow non-flameout device which can solve the problems that petroleum in an oil-gas separator adopting a heating furnace to provide natural gas is excessive and overflows from a top natural gas pipeline, the natural gas pipeline is blocked by the petroleum and heating of crude oil is affected. The scheme is as follows: the anti-overflow non-flameout device comprises a truncated cone-shaped sleeve which is arranged in the positive direction in a gas outlet at the top end of the oil-gas separator, the outer edge of a small circular surface at the top end of the sleeve is hermetically connected with the inner edge surface of the gas outlet, a gap exists between the outer edge of a large circular surface at the lower end of the sleeve and the inner edge surface of the gas outlet, a blocking piece extending into the truncated cone-shaped sleeve is fixedly arranged on the circumference on the lower end surface of the sleeve, an isolation plate is arranged in the sleeve, the lower end of the isolation plate is connected with a floating ball arranged below the sleeve through a connecting rod, and a plurality of ventilation circular holes are uniformly distributed on the circumference at the top of the side surface of the sleeve. The anti-overflow non-flameout device provided by the invention can prevent a large amount of petroleum from overflowing into other devices from the natural gas pipeline at the upper part of the truncated cone-shaped sleeve, and can ensure that natural gas enters the pipeline from the circular holes at the top of the truncated cone-shaped sleeve so as to ensure the normal operation of production.

Description

technical field [0001] The invention belongs to the field of crude oil separation, in particular to a crude oil separation system. Background technique [0002] In the process of oil storage and transportation separation, crude oil often solidifies due to low temperature, thereby blocking the pipeline, causing high friction and affecting production. In order to solve this problem, heating oil is an effective measure to solve oil solidification. Using heating The oil and gas separator in front of the furnace provides fuel for the heating furnace through pipelines, but the pressure of the oil extracted from the oil production well is unstable. When the pressure is high, the oil and gas separator can be filled quickly, and the outlet of the oil and gas separator cannot be transported outward. Part of the crude oil overflows from the natural gas port with the natural gas, and the natural gas is used as fuel to supply the oil heating equipment-heating furnace through the pipeline...
