Combined Carbon Capture and mineral Carbonation in a continuous Process: a technological breakthrough in industrial decarbonisation – 4CP

The 4CProcess project aims to develop a continuous eco-efficient process for intensifying the capture and precipitation of CO2 into carbonate salts. 4CProcess represent a technological breakthrough in industrial decarbonisation. This new dynamic process is inspirited to an innovative elastic foam-bed reactor that employs a simple crankshaft, a technology that has been in use since antiquity, and a structured packing (open-cell elastomer foams). The 4CProcess significantly enhances the transfer of gas to water, offering an innovative integration of the functions of dissolving a porous matrix (cation sources) and precipitating carbonate salts in a continuous flow. The 4CProcess process is designed to enhance transfer efficiency and facilitate the filtration and unclogging of columns during the precipitation of carbonate salts. This innovative methodology paves the way for a sustainable and continuous process for CO2 capture and recovery from industrial flue gases.
From a scientific research perspective, the 4CProcess project will allow an investigation into and understanding of complex and dynamic multiphase processes. The project is designed to achieve a balance between experimental research and modelling, with a particular focus on precipitation and dynamic filtration in gas/liquid flows. Finally, 4CProcess aims to reduce CO2 emissions from production sites (such as cement works) by recycling waste materials (such as concrete rubble), which act as a porous matrix loaded with elements of interest (calcium). The project is part of a strong industrial/societal demand and will benefit of the expertise of two laboratories and the industrial expertise of a major player in cement manufacturing.
