Acid gas treatment for natural gas

Q: Does this technology support carbon capture and Enhanced Oil Recovery (EOR)?

Yes, the membranes concentrate CO2 for liquefaction and sequestration. For EOR, the technology sustains reservoir production through CO2 reinjection. Our systems minimize valuable hydrocarbon losses.

Air Liquide’s robust membrane solutions efficiently remove CO₂ from natural and associated gas streams, onshore and offshore, for pipeline specifications and Enhanced Oil Recovery (EOR).

Excess CO₂ removal is critical and costly. Air Liquide membranes provide a compact, efficient, tailored solution to meet strict pipeline, EOR, and carbon capture requirements.

FPSO Projects: Large scale CO₂ removal in challenging offshore environments

Air Liquide has delivered multiple CO₂ removal packages for offshore applications in Floating Production, Storage, and Offloading (FPSO) vessels. Offshore FPSOs are known to be challenging with stringent processing requirements at remote deepwater locations, where weight, footprint, and operational simplicity are paramount. The successful deployment of ALaS membranes demonstrates our scalability of the solution and robustness of operation, all while contributing to improving methane recovery for the customer and avoiding CO₂ emissions. The picture shows our membrane skid package being delivered and further integrated at the customer’s processing site.
