Description

Novel gas-liquid separator

Technical Field

The utility model relates to a gas-liquid double-phase separation field is a novel vapour and liquid separator who is used for oil-gas separation in the oil gas field development process.

Background

Natural gas is transported in pipelines, often accompanied by condensation or reverse condensation phenomena, as the temperature and pressure vary. When condensation occurs, condensate water and oil condensate appear in the pipeline, and these condensate water and oil condensate form tiny liquid drops in the pipeline under the impact of the high-speed gas flow and are entrained in the natural gas. Meanwhile, the liquid drops can combine with chloride ions in natural gas and carbon dioxide and sulfide in air, and acidic substances are formed to corrode metal equipment such as pipelines and compressors. If the natural gas contains water drops and liquid hydrocarbons, the sealing effect of the compressor can be affected, and the blockage of a pressure regulator of a gas system can be caused. Therefore, to ensure the life and proper operation of the gas transmission equipment, the natural gas needs to be purified.
