Industrial Gas Filter Elements for Gas Turbines & Compressors

Key function: Remove particulate matter (dust, sand, salt aerosol) from atmospheric air before it enters gas turbine compressors or reciprocating units. Critical for protecting blade surfaces from erosion and maintaining isentropic efficiency in Siberian and Arctic conditions.

Key function: Remove liquid hydrocarbons, water aerosol and solid particles from natural gas before downstream processing. The coalescing mechanism merges sub-micron droplets into larger ones for gravity separation — critical for protecting turboexpanders, molecular sieve beds and cryogenic heat exchangers.

Key function: Two critical subsystems. Lube oil filters protect main oil pumps, bearings and gearboxes from wear particles — typically 3–10 μm at 16–32 bar. Dry gas seal filters provide sub-micron (0.3–1 μm) clean buffer gas protecting the precision seal faces. A DGS failure means an immediate unit trip and potential secondary damage.

Key function: Protect amine solvent circuits from particulate contamination and hydrocarbon carryover that causes foaming, fouling and capacity loss in contactor towers. Also covers TEG glycol dehydration filtration and activated carbon guard beds for mercury removal upstream of cryogenic plants.

Key function: Remove free water and solid contaminants from refined products to meet export specifications — jet fuel must be <15 ppm water. Coalescer-separator systems use two stages: a coalescing element to merge fine droplets, then a separator element to repel coalesced water.

Key function: ASU plants require ultra-clean air feed to prevent blockage of molecular sieve beds (13X zeolite) and plate-fin heat exchanger channels. Categories: intake pre-filters, after-cooler filters, molecular sieve dust filters, and product O₂/N₂ particulate filters.

Coalescers and separators protect molecular sieve beds, turboexpanders and cryogenic exchangers. Amine systems need particle and carbon filtration to avoid foaming. Key parameters: inlet pressure, water content, droplet size distribution.

Requires media selection resistant to aggressive media and elevated temperature. Standard cellulose media may be unsuitable — glass fibre and stainless mesh constructions are typically specified. Key parameters: temperature, chemical compatibility, differential pressure limits.

Free-water removal from refined products to meet export specification. Two-stage coalescer-separator design is standard. Key parameters: water ppm target, flow rate, product compatibility, sanitary requirements.

Intake filtration protects turbine blades from erosion; ASU feeds require sub-micron cleanliness to avoid zeolite bed blockage and cryogenic channel fouling. Key parameters: dust concentration, ambient temperature, required filtration efficiency.
