FLS semi dry scrubber meets expectations at Norwegian cement plant

To comply with the Gothenburg Protocol, a FLSmidth gas suspension absorber, FLS-GSA® semi-dry scrubber was installed as an alternative to a more expensive wet scrubber at Norcem AS, Brevik cement plant in Norway. The F.L. Smidth semi-dry scrubber system installed at the Brevik plant has exceeded its designed performance, achieving 97.3% reduction of SO2 emissions and 95.2% reduction of HCl emissions. It has proven that it can achieve reductions in SO2 and HCl emissions that are similar to what can be achieved in a more expensive wet scrubber system. Emissions testing has shown that semi-dry scrubber system also gives the plant the capability to reduce mercury (Hg) emissions by 90%. To achieve this Mercury reduction on a long-term basis, the plant would only need to start shuttling dust from the semi-dry scrubber system to the finish mill.
