Taiwan Cement Corporation (TCC) announced the signing of a memorandum of cooperation on February 1, saying that it would cooperate with ThyssenKrupp Polysius (tkPOL) of Germany to develop new carbon sequestration technology. TCC Chairman Nelson Chang and tkPOL CEO Pablo Roman Hofelich signed the document at a ceremony on January 31,
according to the Economic Daily News.
"Cement created the civilized society we live in today," Zhang Anping said. However, we are also emitting greenhouse gases. This cooperation aims to solve this problem. He added.
According to the Central News Agency, Taiwan Cement explained that the technology involves the introduction of pure oxygen into the cement combustion process. In cement manufacturing, powdered limestone is heated with other materials to produce clinker , which is then mixed with small amounts of limestone and gypsum to produce cement. By introducing pure oxygen, up to 90% of carbon dioxide can be captured during limestone calcination, while reducing the energy required for carbon capture
, TCC said.
TCC also said that the carbon dioxide captured in the future will not only provide services for industries such as industrial welding, chemical industry and food processing, but will also be consistent with the authorities' policies.
Taiwan Cement said it would use the kiln at the Heping plant in Hualien as a test site, and the project is expected to be completed by 2026. The company aims to develop a large-scale commercial core technology by 2030 to achieve carbon capture of 100000 tons per year. Taiwan Cement explained that tkPOL, which is working together this time, is also assisting Heidelberg and other well-known European cement companies in the Catch4Climate forward-looking carbon capture project. At present, it has built a pure oxygen combustion kiln system for cement plants in Germany, which uses pure oxygen to enter the combustion process. By increasing the concentration of carbon dioxide produced during clinker calcination, Purified treatment and reuse or direct liquefaction and storage are carried out to achieve carbon reduction benefits, and then synthetic fuels with carbon reduction effects are developed.
