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.
