Progress has been made in the “CI4C” carbon capture, utilization and storage (CCUS) project in the Mergelstetten cement plant in Germany. This is a € 120m joint venture project by Schwenk, Buzzi-Dyckerhoff, Heidelberg Materials and Vicat with an oxyfuel process for CO2 capture in Schwenk’s cement plant. A new rotary kiln with a 450 tpd clinker capacity for the thyssenkrupp Polysius pure oxyfuel calciner has been installed (photo credit: Armin Buhl). The CO2 purification unit will be delivered by Linde, the liquefied oxygen plant will be from Westfalen AG. The complete oxyfuel system is expected to be commissioned in the 1.Q 2025.
