Products Description
Our natural gas amine filters are designed to remove suspended solids, corrosion by-products and carbon fines from circulating amine solutions, ensuring consistent gas desulfurization performance. In modern natural gas processing, amine filter cartridges are critical for producing pipeline-grade gas free of H₂S and CO₂. By capturing contaminants before small particles can contaminate contactors, regenerators and packed bed towers, they help maintain optimal amine purity and extend equipment life.
Product Classification
| Types | Material | Micron Ratings | Use Case |
| Pleated Depth Filter Cartridges | Polypropylene (PP) microfiber or PTFE-coated media | 1 µm to 50 µm (customizable) | Low‐to‐medium particulate loads; cost‐effective, disposable |
| Stainless Steel Sintered Mesh Cartridges | 316L sintered wire mesh (multiple layers) | Typically 5 µm, 10 µm, or 25 µm | Stable at 446 °F and 35 bar; reusable after cleaning |
| High Flow Filter Cartridges | Polypropylene with depth‐grade structure | 3 µm to 20 µm | Severe conditions (corrosive amines at elevated temperatures); long service life |
| Coalescing‐Depth Hybrid Cartridges | Layered fiber media + hydrophobic coatings | 0.5 µm to 2 µm for water/amine separation; 5 µm to 10 µm for solids | Simultaneous removal of entrained water and fine particulates in circulation loop |
Features
High Filtration Efficiency
- ≥ 99.5 % removal of particulates ≥ 5 µm (metallic cartridges)
- ≥ 98 % removal of particulates ≥ 10 µm (polymeric cartridges)
01
Chemical & Temperature Resistance
- Stable in amine solutions up to 230 °C (metallic); up to 150 °C (polymeric).
- Corrosion‐resistant materials prevent degradation in sour service (H₂S, CO₂).
02
Low Differential Pressure (ΔP)
- Engineered pore structures minimize initial pressure drop (< 0.2 bar), optimizing pump energy usage.
03
Modular & Scalable
- Wide range of lengths (5″–40″) and diameters (2.5″–6″); multiple cartridges can be manifolded for high‐flow requirements.
04
applications
⭐ Amine Gas Sweetening Units
- Contactor Protectors: Pre‐filter rich amine leaving the absorber to prevent solids buildup in the regenerator.
- Regenerator Pre‐Filters: Protect reboiler tubes from fouling by sulfide sludge and carbon deposits.
⭐ Gas Dehydration Pre‐Filtration
- Upstream of glycol contactors: filtering amine from dehydration units when used in blended processes.
⭐ LNG Liquefaction Pre‐Treatment
- Prior to cryogenic processes: remove fine amine contaminants that may form solids at low temperatures.
⭐ Pipeline Gas Conditioning
- Amine filter cartridges installed at intermediate compression stations to maintain amine loop integrity.
Real Customer Success Stories
Case Study 1: Natural Gas Processing Plant (USA)
Background:
A mid‐size gas plant processing 200 MMscfd of sour gas faced frequent contactor fouling due to high levels of corrosion byproducts in the MDEA solution.
Solution:
Installed four 20″ stainless steel sintered mesh amine filter cartridges (10 µm rating) in duplex housings on the rich amine line.
Results:
- 30 % Reduction in regenerator fouling frequency (from monthly cleaning to quarterly).
- 25 % Extended life of stripper packings due to lower particulates.
- Savings: Estimated USD 120,000 annually in maintenance costs and lost production time.
FAQ
Q: What micron rating should I choose for my natural gas amine filter?
A: For typical lean‐rich amine loops handling moderate solid load, a 5 µm–10 µm cartridge balances particle removal and ΔP. For severe fouling, consider 3 µm sintered metal cartridges. Always evaluate your specific amine analysis (TSS, iron content) to determine the optimal rating.
Q: How often should the filter cartridge be replaced?
A: Replacement frequency depends on contaminant load. As a guideline: Disposable PP Cartridges: 3–6 months under normal loading (~ 50 mg/L TSS). Metallic Cartridges: Clean/re‐use every 6–12 months; replace after 3–5 cleaning cycles, depending on media integrity.
Q: Are your filter cartridges compatible with all common amines (MEA, DEA, MDEA)?
A: Yes. Our filter media (polymeric, stainless) are chemically inert to primary solvents (MEA, DEA, MDEA) and typical corrosion inhibitors. For specialized blends (e.g., AMP‐activated amines), consult our technical team for compatibility confirmation.
