How does CO₂ capture and storage work? [ Return towards Capturing and storing CO₂ ]

Air Liquide is present across the CCS chain: the Group supplies the oxygen needed for oxycombustion. To concentrate CO₂, Air Liquide researchers develop special burners for use with oxygen.

Oxycombustion technology is now being implemented at a power plant to capture and store CO₂. R&D engineers are developing equipment to enrich flue gas in CO₂. Finally, CO₂ is purified in a Cryogenic Purification Unit (CPU), ready for compression, transportation and sequestration.
