thyssenkrupp Uhde, Holcim & Technische Universität Berlin have partnered up in a joint project to investigate the use of a novel amine scrubbing technology in cement making for carbon capture. The goal is to significantly reduce CO2 emissions from existing cement plants and at the same time utilize the captured CO2 for other applications. In concrete terms, this includes the development of new mass transfer process equipment that is more efficient and resilient to contaminations. The project is being funded by the German Federal Ministry for Economic Affairs and Climate Action. thyssenkrupp Uhde’s Head of Technology, Innovation & Sustainability Dr Ralph Kleinschmidt said: "Amine scrubbing is already commonly used to recover CO2 from process gases or exhaust gases. Now, we are developing the technology further and optimizing it for the cement industry. Additional applications for capturing CO2 direct at source, such as in waste incineration plants, are also possible."The performance and efficiency of this equipment is being tested using real exhaust gas at the cement plant located in Beckum, Germany. This is paving the way for commercial use. Various possibilities for using the captured CO2 are also being examined, for example methanol or sustainable fuels. With this process, the partners are seeking to make a contribution to the reduction of greenhouse gases, especially in existing cement production plants. These can then be retrofitted with equipment for capturing CO2 from the process gas without further adapting the production process.The cement industry is working on reducing CO2 emissions in a number of ways. Because even with the sole use of renewable energies, the raw materials used in cement production result in CO2 being released and emitted to the atmosphere.
