Rotary Lime Kiln Scrubber

Optimized Wet Scrubber Design for Lime Kilns. A properly designed wet scrubber is a highly efficient approach to controlling lime kiln emissions which contain SO2 and HCl acid gases, metals, and particulate matter. A Venturi scrubber followed by a crossflow entrainment separator has the advantages of a small footprint.
