Products Description
Designed for industries that rely on high purity amines (e.g., gas treatment, pharmaceuticals), the amine solution filter removes organic contaminants, heavy metals, and particulates while recovering >99% of the active amine.
Filtration Technology & Structure
Multi-Layer Depth Media
Graded polypropylene melt-blown fibers form successive pore zones, trapping larger particles on the upstream layers and finest debris in the core.
Rigid Core Support
Glass-filled polypropylene core resists collapse and allows consistent flow even at high differential pressures.
Seamless Construction
Thermally bonded end caps and media eliminate adhesives, preventing contamination of the amine solvent.
Bypass Prevention
Molded upstream and downstream support nets ensure no channeling around the filter matrix.

Features
- Solid Removal Efficiency: Achieves >99.5% capture of particulates ≥5 µm in laboratory challenge tests.
- Corrosion Inhibitor Protection: Polypropylene media is fully compatible with commonly used corrosion inhibitors (e.g., tertiary amines, thiazoles) without leaching.
- Low Extractables: Total Organic Carbon (TOC) ≤ 10 ppm, preventing foaming and solvent discoloration.
- Extended Service Life: Cartridge lifespan typically exceeds 3 months under 100 m³/h flow, reducing downtime for change-outs.
Real Customer Success Stories
Case A: North Sea Platform
After retrofitting with 5 µm amine solution filters, solids build-up in the regenerator preheater dropped by 85%, extending clean-in-place intervals from 2 to 6 months.
Case B: Onshore CO₂ Capture Plant
Installing 10 µm amine filters upstream of the lean-rich exchanger reduced pump seal replacements from quarterly to annual, saving €120,000 per year in maintenance costs.
FAQ
Q: How often should I replace the cartridge?
A: Change frequency depends on solids loading and flow rate. Under standard MDEA service at 200 L/min, expect 3–4 months of operation.
Q: Can I use these filter cartridges with corrosion inhibitor blends?
A: Yes, polypropylene media is inert to most tertiary amine inhibitors; consult us for novel chemistries.
Q: What differential pressure signal indicates a change-out?
A: A rise of 0.8–1.0 bar over baseline typically triggers replacement to avoid bypass risk.
