Revolutionary CO2 Capture Tech Shows 90% Efficiency in Cement Industry Trials
A groundbreaking collaboration between TU Berlin, thyssenkrupp Uhde GmbH, and Holcim is yielding promising results in the quest for a more sustainable cement industry. The partners are jointly testing a new CO2 capture technology that has shown remarkable efficiency in pilot trials.
The innovative system employs a chemical absorption process, known as amine washing, within a rotating apparatus inspired by a washing machine. This unique design, featuring rotating packing elements made of metal foam, offers an extensive surface area, facilitating intense mixing of gas and washing agent.
The rotation also enables the use of concentrated washing solutions, significantly boosting the CO2 absorption capacity per liter of washing agent. In practical tests using real exhaust streams at Holcim's cement works in Beckum, North Rhine-Westphalia, the plant has demonstrated the ability to wash more than 90 percent of the carbon dioxide from the exhaust gases.
TU Berlin, spearheading the project, is not only developing this cutting-edge technology but also working on mathematical models to scale it up to an industrial level. The project underscores the vital role of cooperation between universities and companies in driving technological advancements. While the researcher leading the project at TU Berlin remains unnamed, the project's success is a testament to the collective effort and expertise of all involved.
The new CO2 capture technology, a result of the collaborative effort between TU Berlin, thyssenkrupp Uhde GmbH, and Holcim, is proving to be a significant step towards a greener cement industry. With its high efficiency and potential for industrial-scale application, this innovation could soon become a routine feature in cement production, marking a substantial stride in the fight against climate change.
