LEILAC secures Euro12m from European Union to demonstrate Calix carbon capture technology

Europe: The Low Emissions Intensity Lime And Cement (LEILAC) consortium has secured Euro12m in funding over five years from the European Commission Horizon 2020 Grant programme to test Calix’s direct separation process to capture CO2 emissions from cement and lime production. The consortium comprises HeidelbergCement, Cemex, Tarmac, Lhoist, Amec Foster Wheeler, ECN, Imperial College, PSE, Quantis and the Carbon Trust. The consortium will also contribute a further Euro9m towards the project.

During the first three years, the project will focus on finalising the design of the demonstration plant, to be constructed at the HeidelbergCement plant in Lixhe, Belgium once the necessary permits have been secured. The high temperature Direct Separation Calciner pilot unit will then undergo two years of testing in a standard operational environment, at a feed rate capacity of 240t/day of cement raw meal and 200t/day ground limestone respectively, on a continuous basis for several weeks.

Fundamental research on the process demands and performance will be carried out to demonstrate that the technology works sufficiently and robustly enough to be scaled up to full operational use. The project results will be shared widely with industry at key intervals during the testing.

Calix’s direct separation technology is achieved by re-engineering the process flows used in the best available technology for lime and cement calcination. Carbonate calcination occurs by indirect counterflow heating, and consequentially the flue gases are not mixed with the CO2 emitted from the carbonate minerals. This technology is already operating at a commercial scale for magnesite calcination. It does not require any separation technologies, new materials or processes. The technology is complementary with other carbon capture methods already developed in the power and cement sector, such as oxyfuel, and can make use of alternative fuels.
