[0002] Natural gas filter separators are mainly used to remove solids and liquids from natural gas. They are composed of cyclones or blades, fine filter agglomeration, liquid collection bags, and sewage discharge systems. They first filter solid impurities in natural gas and condense droplets, and then separate the agglomerated droplets. The filter element is made of glass fiber and other high-performance synthetic fiber materials.

[0003] Natural gas filter elements are often made of stainless steel mesh and polyester glass fiber composite membrane. Stainless steel metal filter elements are often used to remove dust and pipeline impurities in the gas, while polyester glass fiber filter elements have a good separation effect on water and oil components in the gas.

[0004] The polyester glass fiber filter element is made of high-density gradient glass fiber. In order to reduce damage and leakage, it is designed as an integral single-piece tube structure. The surface of the filter element is treated with hydrophobicity and oleophobicity to meet various precision grade requirements. For high-pressure working conditions, stainless steel can be used as the outer protective layer and the internal stainless steel skeleton support.
