With the increased use of alternative fuels in cement production, excess chlorine in the kiln system has become a common problem. To address this issue, Cimpor, a leading cement producer in the Iberian region, has asked FLSmidth to provide a chlorine bypass solution for their site in Souselas, Portugal. Following a new EPC order from Cimpor received at the end of last year, FLSmidth will deliver a chlorine bypass solution, eliminating chlorine build-up in the flue gas as Cimpor plans to increase their alternative fuel rate to more than 60%. Work on the chlorine bypass is expected to begin in the Q3 of 2021, with production returning to normal in early 2022. On top of the obvious benefits of increasing their fuel substitution, such as lower carbon emissions and financial savings. They are seeing improved waste handling infrastructure in the local area, which has made it an easy decision to make. FLSmidth is familiar with their Souselas site and has played an important role in delivering a solution that will enable this next phase of their sustainability journey, Paulo Evangelista, Project Manager at Cimpor, told the media. They upgraded the kiln and installed an SF Cooler and Downdraft calciner at the site in 2001, giving them a head start on the bypass upgrade. Cimpor anticipates that refuse-derived fuel will account for approximately 40% of future heat consumption (RDF). RDF tends to increase chlorine concentrations in gas streams. When chlorine can no longer be absorbed during the calcination and clinkering processes, the flue gas is routed through the bypass, cooled, and filtered. Excess chlorine can often be added at a later stage of the process. The benefits of the chlorine bypass, such as lower carbon emissions and higher substitution rates, make this solution a showcase for FLSmidth's MissionZero cement programme. FLSmidth's MissionZero sustainability goal is for customers to be able to run cement production with zero emissions by 2030.
