Debottlenecking & Hybrid Applications

Using membrane technology to enhance gas processing for brownfield and hybrid projects

Air Liquide's MEDAL and PEEK-Sep membrane technologies provide tremendous flexibility in meeting your gas processing needs. From brownfield projects to greenfield hybrid applications, our membranes can operate alone or in conjunction with other gas purification technologies to provide the lowest cost of ownership in purifying your natural gas stream.
MEDAL 8-inch NG2 replacement modules installed in existing tubes on cellulose acetate membrane skid. Adapters supplied by Air Liquide complete the gas flow connections to the ports in the end flanges.

Drop-in Cellulose Acetate Membrane Replacements

Our MEDALTM Model 5840 membranes and PEEK-Sep S-Guard membranes are designed as drop-in replacements for cellulose acetate membranes that have not met your gas processing requirements or have required frequent and costly replacment due to their inability to maintain selectivity. The Air Liquide replacements will meet your CAPEX requirements and provide improved longterm OPEX. Use of our robust PEEK-Sep membrane further enhances your operation in cases where the pretreatment for the cellulose acetate membrane was inadequate. The PEEK-Sep membrane requires minimal pre-treatment, simply a coalescing filter upstream.

Brownfield Projects & Hybrid Applications

If your current adsorption or absorption purification system is aged or no longer meeting throughput or purification requirements, Air Liquide Advanced Separations' (ALaS) membrane technology can provide you with a simple and cost-effective fix. Our MEDALTM or PEEK-Sep technology can supplement a molecular sieve unit or TEG unit with dehydration or pickup the slack for an aging amine unit that is slipping either H2S or CO2 into the product stream. This same combination of technologies can be applied to greenfield projects to maximize purification efficiency and minimize total cost of ownership.

Advantages

  • Increase capacity of aging adsorption or absorption systems
  • Hybrid applications may provide the lowest total cost of ownership for end-user
  • Upgrade old membrane technology to state-of-the-art higher performing hollow fiber technology
