William Blythe: Stannic Chloride Plant - Case Study
Problem
Installed in 1998, this Turboscrubber® unit treats the exhaust gases from various reactors, stills and packaging stations in William Blythe’s Tin Plant Recovery Section at Stannic.
Solution
The unit simultaneously scrubs SnCh vapours, their hydrolysis product HC1, and SnOj precipitate to high efficiencies. It was supplied as a replacement and upgrade for an existing packed column scrubber which was prone to blockage by the precipitated solids. The SnOj precipitate is discharged with the spent scrubbing liquor and its valuable tin content recovered.
Results
Osprey/FTL’s fluidised bed Turboid® technology has shown exceptional ability to simultaneously absorb gases and remove fine dust 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. Turboid®’s non-clogging nature permits the use of limestone slurries, trade effluents and biomass as scrubbing media.
