TurboScrubber: Engelhard: Metals Recovery Incinerator - Case Study

Solution
The plant was upgraded in 1997 and 1998, a Turboscrubber® system was installed in series with an existing Venturi scrubber. Additionally a sophisticated control system was designed and installed for flexible operation of this versatile plant. Osprey/FTL’s fluidised bed Turbopak® technology has shown exceptional ability to simultaneously absorb gaseous components and remove fine dust and soot particles across a wide range of industrial applications. In addition the system’s high mass and heat transfer rates offer considerable reductions in scale and cost for gas cleaning plant, for example on chemical processes, dryers, boilers and incinerators. Turbopak®’s non-clogging nature permits the use of limestone slurries, trade effluents and biomass as scrubbing media.

Results
A reducing in high fine particulate loadings up to 750 mg/m3 down below 10 mg/m3, better absorption of HCl, and reduced cooling gases for efficient plume suppression.
