Clean/Dirty CO2 separation

Clean CO₂ produced with up to 100 ppm vol of H₂ residual content.
Simple solution.
Low Capex.

Considering that the usual CO₂ stream produced at BLs in an existing (and new) CO₂ removal section contains a significant amount of H₂ (more than 0.1% and very often more than 0.2% mol), Casale can supply a new technology to provide a very low H₂ content in a Clean CO₂ stream generated in an existing or in a new CO₂ removal section.

Thanks to this patented technology developed by Casale it is possible to reduce the H₂ content in the Clean CO₂ up to 100 ppmv, with usual guaranteed value around 500÷600ppm vol. This technology allows to recover up to 70-80% of clean CO₂ (the balance is made by dirty CO₂).

Casale has already applied this technology in a couple of plants located in Russia, in particular in one plant Casale modified the top of the regenerator while in another plant Casale realized an improved external pre-flash to enhance the CO₂ clean fraction versus CO₂ dirty one.

This technology can be applied both to amine and hot potassium-based CO₂ removal section.
