Since 2015, CO2 Solutions has worked with multiple suppliers of contact technology intensified by a rotating bed in order to help reduce the size of their enzymatic capture unit for carbon reuse to optimize the integration of an RTB.
The partnership lead to a considerable decrease in the size of the CO2 absorption system so it could be better adapted to constrained industrial spaces in power plants, oil refineries and other carbon-emitting plants. The system itself is now thirty times more compact than a conventional unit, an improvement that has resulted in an important reduction of initial investment costs. The installation of this smaller and lighter carbon capture unit does not require any new supporting structure or reinforcement of existing structures.
Conventional unit compared to CO2 Solutions’ rotating packed bed unit
This commercial example is for the capture of 90% of CO2 emissions from a natural gas fired boiler based on a scale of 300 tonnes of CO2 per day.
