Gas Filter

Product Description

In the fields of petrochemicals, natural gas processing, air separation and oxygen production, and fine chemicals, the efficient and reliable purification and filtration of process gases, instrument air, and special gases are the core links to ensure the safe and stable operation of compressors, precision instruments, catalysts, and downstream processes. The GLY, GLT, GLUP, GLUU, GLUD, and GLUX gas-liquid separation filter series provided by Hubei Wan'an Environmental Protection & Petrochemical Equipment Co., Ltd. are professional gas purification solutions designed specifically for such harsh demands. As an indispensable "safety guard" in pipeline systems, they have become the standard configuration for protecting key equipment, improving gas purity, and ensuring process safety and efficiency with their efficient solid-gas separation capacity, wide adaptability to working conditions, and sturdy and reliable structure.

Core Functions & Superior Performance

This series of gas filters is designed, manufactured, and inspected in strict accordance with national and industry standards such as HGJ532-91, GB150-98, and SH/T3411-1999. Its core lies in the use of precision-manufactured filter screens or filter elements. When gas containing solid impurities enters the filter, the impurities are efficiently intercepted on the surface of the filter screen or inside the filter cartridge, and the clean gas is discharged from the outlet, thereby realizing the purification of the gas medium. The product series covers everything from simple pipeline filters to high-performance composite equipment integrated with gas elimination and separation functions, which can meet different levels of needs from conventional protection to precision processing.

Key Customer Value

Efficient Purification & Equipment Protection: Adopting high-precision filter screens (with optional mesh sizes) or special filter elements, it can effectively filter out solid impurities such as particles, dust, and rust in the gas, significantly extending the service life of key equipment such as compressors, flow meters, control valves, and catalysts, and reducing unplanned downtime and maintenance costs.
Wide Adaptability to Working Conditions: The nominal diameter of the product covers DN20 to DN500mm, and the nominal pressure range is PN0.6 to PN6.3MPa. The design temperature can reach -20℃ to 300℃ for carbon steel and -190℃ to 400℃ for stainless steel. The applicable media include almost all industrial gases such as air, oxygen, nitrogen, hydrogen, hydrocarbons, ammonia, and chlorine. The PTFE (F4)-lined model can withstand highly corrosive gases.
Optimized Structure & Low Pressure Loss: The scientifically designed flow channel and large effective filtration area ensure extremely low system pressure drop while achieving efficient filtration, reducing energy consumption. For example, the GLY type filter has an optimized effective filtration area and strong flow capacity.
Diverse Selection & Integrated Functions: Various structural types are available, including GLY (straight-through), GLT (T-type), GLUP/GLUU (basket-type), GLUD (multi-filter element), and GLUX (gas-liquid separation filter), meeting different installation space and functional needs. The GLUX gas-liquid separation filter is further integrated with the functions of filtration and removing liquid droplets (mist) in the gas, providing a one-stop solution for gas source purification.
Durable & Easy Maintenance: The shell material can be selected from carbon steel, stainless steel (304/316L), alloy steel, and fluoroplastic-lined plastic, with strong corrosion resistance. The filter element or filter basket adopts a detachable design, which is easy and quick to clean or replace, greatly reducing the difficulty and cost of long-term operation and maintenance.

Typical Application Scenarios

Process Gas Purification: Impurity filtration of process gases such as synthesis gas, cracked gas, and reformed hydrogen before entering compressors and reactors.
Instrument Air & Utility Gases: Precision filtration of factory instrument air, nitrogen-sealed nitrogen, and purge gas to protect pneumatic instruments and valves.
Natural Gas Processing: Removal of solid particles and liquid droplets from wellhead natural gas and pipeline natural gas.
Air Separation & Special Gases: Pretreatment of air in air separation plants, and terminal filtration of high-purity gases such as oxygen and argon.
Environmental Protection & Emission: Pre-filtration of particles at the front end of waste gas treatment systems.
