LFX-CLNG™ High-Pressure Gas Coalescing Filter Cartridges

FiltraCore Asia’s LFX-CLNG™ gas coalescing filter cartridges deliver high-efficiency removal of aerosols, entrained liquids, and fine particulate from LNG and natural-gas transfer streams. Engineered for stable operation in high-pressure gas systems, these cartridges support reliable gas-phase conditioning across a wide range of upstream and downstream process equipment.

Designed for use in vaporizers, heat exchangers, metering trains, compressors, and LNG terminal infrastructure, LFX-CLNG™ cartridges help protect critical assets from liquid carryover, oil mist, solvent aerosols, and fine solids. The high-strength coalescing media promotes consistent separation performance, supporting system reliability, equipment longevity, and predictable operating conditions in demanding industrial gas networks.

Technical Specifications
  • Media & construction: Multi-layer borosilicate microglass coalescing media engineered for fine aerosol capture, integrated with an oleophobic / hydrophobic drainage layer to promote liquid coalescence and gravity drainage. Positive O-ring sealing design. Element hardware available in polymer or metal constructions, with 316L stainless steel caps and cores offered for corrosive, sour-gas, or aggressive service conditions
  • Efficiency efficiency (aerosol): High-efficiency gas coalescing performance up to 99.999% removal at 0.3 µm (DOP aerosol), with ≥99.7% removal of solid particulates >0.3 µm, dependent on element grade and service conditions.
    (Target aerosol efficiency at 0.3 µm should be specified at time of order.)
  • Element size (large-OD format): Industry-standard large outside diameter (OD) elements, nominal Ø ≈ 152 mm (6″) × 1016 mm (40″) length. 1524 mm (60″) lengths available on selected element families
  • End configuration / sealing: Supplied as SOE or DOE to match vessel internals, including tube sheets, tie-rods, and seating geometry. O-ring size, material, and location must be specified to suit the installed housing (e.g. PECO-style or equivalent gas filter-coalescer vessels).
    Sanitary 222/226 end styles are not typical for large-OD gas coalescing elements.
  • Flow path / coalescing architecture: Two-stage coalescing architectures are common, comprising primary aerosol coalescence followed by drainage. Flow direction is element- and vessel-specific; many designs employ staged outside-to-inside followed by inside-to-outside flow within the element family.
    Reverse-flow operation is not permitted and must be avoided
  • Clean Δp / sizing reference: Clean Δp is dependent on element grade, gas composition, operating pressure, temperature, and vessel internals. Element selection and sizing should reference grade-specific Δp-versus-flow curves provided by the manufacturer for the actual operating conditions
Applications
  • LNG terminals & regasification — installation downstream of vaporizers and upstream of meters or compressors to remove liquid aerosols and fine solids from send-out gas, helping maintain pipeline cleanliness and analyser stability
  • Boil-off gas (BOG) recovery & fuel-gas conditioning — coalescing at compressor suction or discharge to limit lube-oil carryover and polish fuel gas supplied to gas turbines, boilers, and heaters
  • Pipeline & custody transfer systems — upstream of metering/prover skids, pressure regulators, and analysers to strip oil mist, condensate droplets, and particulate contamination
  • Gas dehydration & sweetening trains — coalescing around amine and glycol contactors and regeneration loops to mitigate solvent aerosol carryover and protect downstream turbomachinery
  • Power generation & industrial users — fuel-gas polishing for turbines, engines, and HRSGs in chemical plants, utilities, and industrial energy systems
  • Hydrogen-enriched NG (H₂ blends) — coalescing of mixed gas streams in distribution or industrial use where material compatibility and applicable safety standards are met (elastomers and metallics to be confirmed for the specified H₂ fraction)
