Lean amine filter is critical to maintaining the performance of the amine circulation system. Unfiltered regenerated lean amine containing residual solid particles can wear pumps, valves, and other equipment, reducing mass transfer efficiency in the absorption tower. Hierarchical filtration with media like metal woven mesh or polypropylene melt-blown cartridges, tailored to process conditions, optimizes lean amine quality and ensures long-term stable operation of desulfurization/decarbonization processes.
High-Flow Pleated Filters
Design: Multi-directional pleated structure for 30% higher surface area.
Use Case: Large-scale refineries or LNG plants requiring uninterrupted high-volume flow rates.
Key Advantage: Extended service life (up to 18 months) with minimal ΔP buildup.
Standard Cartridge Filters
Design: Single-layer or dual-layer polypropylene/glass fiber media.
Use Case: Routine filtration for small to mid-sized gas sweetening units with moderate particulate loads.
Key Advantage: Cost-effective solution with quick replacement cycles.
Coalescing Filters
Design: Hydrophobic glass fiber media with graded pore structure.
Use Case: Critical for amine systems contaminated with emulsified hydrocarbons or free oil.
Key Advantage: Achieves <10 ppm hydrocarbon content, preventing foaming and column fouling.

Q: How to select materials?
A: Weak Alkaline Amine (e.g., MDEA): Use PP or nylon; Strong Alkaline Amine (e.g., DEA): Opt for PTFE or stainless steel; High-Temperature Conditions: Choose metal or glass fiber.
Q: What filter cartridges for high-temperature amine solutions (>80°C)?
A: Prioritize stainless steel sintered filter cartridges or glass fiber filter cartridges (temperature resistance ≥150°C).
Q: Do you offer technical support?
A: 24/7 global support, including startup assistance, monitoring, and troubleshooting.
