What's gas filter cartridge?

The natural gas filter element is suitable for gas-liquid and liquid-solid separation of natural gas, artificial gas and other non-corrosive gases, such as nitrogen, carbon dioxide, propane, butane, etc. It is an essential separation and purification equipment component for gas gathering and transmission pipelines, gas gathering stations, gas compression stations, distribution stations, cleaning stations, terminal stations and various application fields. It can effectively filter dirt in the pipeline and fragments peeled off from the pipe wall to ensure the safe operation of gas transmission and gas equipment, and meet the quality requirements of pipeline transportation and users for natural gas;

·Core function: For natural gas transmission or processing systems, filter solid particles, liquid hydrocarbons and moisture to protect pipelines and equipment;

·Material: Composite structure: outer metal mesh (coarse filter ) + middle layer coalescing layer (to capture droplets) + inner layer separation layer (gas-liquid separation); special coatings (such as epoxy resin) resistant to hydrogen sulfide (H₂S) corrosion;

· Working principle: multi-stage filtration: first intercept solid impurities, then coalesce droplets, and finally completely separate liquid and gas;

· Advantages: adapt to high pressure (up to 10MPa or more) and high flow rate conditions; high filtration accuracy (solid particles 1-5μm, liquid particles 0.3μm);

· Application scenarios: natural gas long-distance pipelines (filtering dust and liquid impurities); LNG receiving stations (pre-processing liquefied natural gas); gas turbine intake systems (protecting blades from particle wear)
