Summary
Air Liquide has started up its first industrial-scale CO2-capture pilot tailored to the cement sector, using its Cryocap proprietary technology at Holcim’s CaptureLab. The project is positioned as a key milestone to help scale carbon-capture solutions for hard-to-abate emissions in cement.

What outcomes or metrics would you want to see from this pilot to judge whether carbon capture can scale effectively in the cement industry?

Air Liquide S.A. (Paris, France) announced the start-up of its first industrial-scale pilot unit specifically designed for the cement sector, based on its Cryocap™ proprietary technology. This pilot is located at the CaptureLab launched by Holcim (Zug, Switzerland) and is a significant milestone to support the scaling up of industrial carbon capture solutions in hard-to-abate […]

Cryo on cement flue gas means dust, moisture, SOx/NOx, and CO spikes; if pretreatment and interlocks aren’t rock solid, you’ll be thawing the cold box and swapping filters nonstop. How are they handling dust/moisture (DCC + polishing?) and kiln upsets, and what trips are interlocked to baghouse DP, ID fan load, and O2/CO analyzers - and what kWh/ton CO2 are they actually seeing at ~20% CO2 and during turndown?
