Carbonate CO₂ scrubbing process II (ECO₂) – Practical experience and technical optimisation

The flue gas scrubbing was researched as part of the AiF IGF research project (IGF No. 18560 N, [1]). The project includes the optimisation of CO₂ removal from the flue gas with simultaneous formation of a mineralised water, which is to be used directly for water body remediation and buffering. In this process, the natural limestone-weathering cycle is mimicked and artificially accelerated within the mobile demonstration plant. The advantage of the process is the long-term conversion of limestone powder, water and CO₂ into calcium bicarbonate in dissolved form, which can be used as a pH...
