The petrochemical amine filter is engineered to deliver precision contaminant removal in oil refinery amine gas treating processes. Designed for independent stations and centralized treatment units alike, this filter cartridge effectively eliminates particulate matter, corrosion byproducts, and degradation residues from amine solvents (e.g., MDEA, DEA, MEA).
⭐ High Dirt-Holding Capacity
Pleated depth media design achieves ≥15 g of particulate retention per 10″ cartridge (5 µm), extending service life to 3–6 months under typical refinery loads.
⭐ Superior Corrosion Resistance
All wetted polymer parts are polypropylene with reinforced polyester fibers; stainless steel core options employ SS316 to resist H₂S-enriched amine.
⭐ Low Pressure Drop
Initial ΔP <0.05 bar (5 µm); maximizes pump efficiency and reduces energy costs associated with circulating amine.
⭐ Chemical Compatibility
Compatible with MDEA, DEA, MEA, DIPA, and hybrid amine blends at concentrations up to 50 wt% and temperatures up to 130 °C.
⭐ Easy Retrofit & Maintenance
Fits most standard 222/226 O-ring housings; no special tools required. Quick-change design minimizes shutdown time (≤15 minutes per vessel).

Case Study: North American Petrochemical Plant – Activated Carbon Polishing
Background: A butadiene extraction unit experienced trace hydrocarbon carryover into MDEA solution, leading to odor complaints and minor corrosion in downstream lines.
Solution: Added an activated carbon-coalescing cartridge after a 5 µm pleated filter to specifically target hydrocarbons.
Outcome:
Q: Can these petrochemical amine filter cartridges handle iron sulfide sludges?
A: Yes. Our 25 µm depth-wound and 50 µm depth-wound polypropylene cartridges are specifically designed to trap iron sulfide and rust particles up to 50 µm. For extreme fouling, consider oversizing the cartridge length (e.g., 30″ or 40″).
Q: How do I determine the correct cartridge length and flow rate?
A: Match the amine loop flow (in GPM or LPM) to the cartridge's rated flow. For example, a 10″ × 5 µm pleated cartridge handles up to 211 GPM (800 LPM) at ΔP ≤ 0.5 bar. If your flow exceeds this, two cartridges in parallel or a 20″ length assembly is recommended.
Q: Which media is best for high-temperature MDEA?
A: For temperatures above 90 °C, we recommend PPS depth-wound cartridges (operating up to 150 °C). For even higher temperatures or aggressive degradation byproducts, our PTFE-coated polyester pleated cartridges (up to 120 °C) resist media breakdown.
