Industrial gas major Air Liquide has commissioned its first industrial-scale pilot unit for the cement sector at cement manufacturer Holcim’s carbon capture demonstration facility in Martres-Tolosane, France.
Air Liquide’s Cryocap Flue Gas (FG) pilot unit will remove impurities from flue gas and pre-concentrate carbon dioxide (CO2) before final CO2 purification, with a capacity of 3,000 Nm³/h of flue gas.
Cryocap FG cryogenic technology is designed for CO2 capture from cement grey and white kiln emissions, with a CO2 recovery of over 95%.
Testing is taking place at Holcim’s CaptureLab, a carbon capture demonstration facility for the cement sector developed by Holcim R&D teams in Switzerland and France.
The facility can capture 5–30 tonnes of CO2 per day, with a full-scale installation expected to be around 100 times larger.
Armelle Levieux, member of Air Liquide’s Executive Committee, said, “This new pilot unit highlights Air Liquide’s…ability to scale proprietary technologies from laboratory research to industrial-scale applications.”
Air Liquide builds on over a decade of experience using its Cryocap technology to capture CO2 emissions from hydrogen production in Port-Jérôme, France.
The Accsion carbon capture and storage (CCS) project, a joint venture between Air Liquide and Danish cement producer Aalborg Portland, a subsidy from the Danish Energy Agency.
Cement, the binding agent for concrete, is the most widely used construction material globally, and is responsible for around 7% of worldwide CO2 emissions and 4% of EU emissions, according to the European Commission.
