High-efficiency fine defoaming and desanding separator for natural gas

Abstract

The invention discloses a high-efficiency fine deforming and desanding separator for natural gas. The high-efficiency fine deforming and desanding separator for the natural gas comprises a tank body, wherein a gravity settling chamber is formed at the bottom of the tank body, a cyclone separator is arranged at the center of the gravity settling chamber, a gas defoaming and desanding filter is arranged above an outlet of the cyclone separator, an air inlet of the high-efficiency fine defoaming and desanding separator for the natural gas is formed in the lower part of the tank body and is directly communicated with the gravity settling chamber, and a vent is formed in the upper part of the tank body and is arranged above the gas defoaming and desanding filter. The high-efficiency fine deforming and desanding separator for the natural gas has the advantages that the cyclone separator and a filtration tertiary treatment manner are well combined, especially the density gradient of a filter material in the filter can enable increasing rate of resistance of a filter layer to be greatly reduced, and a resistance formation time is increased by thousands of times compared with a common filter, so that the high-efficiency fine deforming and desanding separator for the natural gas has a broad application prospect.

Description

technical field [0001] The invention relates to gas filtering equipment, in particular to a high-efficiency fine defoaming and desanding separator for natural gas. Background technique [0002] With the application of various development methods in the oilfield, the quality of natural gas raw material gas is getting worse and worse before initial processing, and contains a large amount of mist and fine sand and gravel impurities. The existence of these impurities will cause blockage or even damage to precision pressure regulating equipment and metering equipment. , affecting production and causing losses. At the same time, since solid phase particles are the natural nuclei of water freezing and natural gas hydrate formation under low temperature conditions, their existence exacerbates the problems in the production of gas containing mist and gravel impurities. [0003] In order to eliminate the great harm caused by mist and grit in natural gas, gravity sedimentation separat...
