Three-Phase Coalescing Process:
Pre-Filtration Stage
Removes bulk liquids and particles ≥10µm
Coalescing Stage
Multi-layer media merges sub-micron aerosols into larger droplets
Separation Stage
Hydrophobic barrier allows clean gas passage while retaining liquids
Integrated anti-re-entrainment design prevents collected liquids from being reabsorbed
Pipeline compressor stations
Gas dehydration systems
LNG terminal filtration
Compressed air treatment
Instrument air purification
Biogas upgrading plants
Syngas conditioning
CNG/LNG fueling stations
Aircraft refueling systems
