✅ High Chemical Compatibility:
Resists degradation in contact with acidic gases (H₂S, CO₂) and corrosive amines.
✅ Extended Filter Life:
High dirt-holding capacity reduces replacement frequency and lowers operational cost.
✅ Foaming Control:
Reduces surfactant presence, preventing foaming in the absorber column.
✅ Improved Heat Exchanger Performance:
Minimizes fouling and scaling on heat transfer surfaces.
✅ Modular Design:
Enables quick retrofit into existing amine circuits with minimal modification.
1. Natural Gas Sweetening Units
Filtering rich/lean amine before and after regeneration cycles.
2. Hydrocarbon Refining Units
Desulfurization units (HDS), removing contaminants prior to amine reclaimer.
3. Petrochemical Plants
Protecting process reactors and downstream analyzers from amine impurities.
4. Offshore Gas Processing
Compact skids for FPSO and platform gas treatment.
Q: Will this remove heat-stable salts (HSS) from my lean amine?
A: Yes - our multilayer design targets HSS like formate, acetate, and oxalate causing reboiler scaling.
Q: Compatible with sulfolane-based solvents?
A: Confirm solvent blend - we offer PTFE membrane options for aromatic systems.
Q: Do you offer customized amine based filter lengths or end cap designs?
A: Yes. We manufacture filter cartridge s in non‐standard lengths (50″, 60″) and custom end caps (double o‐ring, flanged) to fit unusual housings. Contact our engineering team with dimensions and operating specs.
