GAS SCRUBBING SYSTEMS


 

Corning Optical Fiber, Abatement Plants
William Blythe, Stannic Chloride Plant
These three TURBOSCRUBBER® units were installed over a 2 year period with last unit commissioned in the summer of 1999. They are installed on the backend of existing abatement plant (bag houses and low pressure Venturi scrubbers) to perform a polishing role to substantially reduce emissions. The units simultaneously scrub fine silicone dioxide particles and absorb Cl2 and HCl gases to maintain emission levels below the enhanced legislative requirements now required. The unique non-clogging feature of the TURBOSCRUBBER® ensures reliable and consistent operation without any increase in gas side pressure drop.
Installed in 1998 this Turboscrubber® unit treats the exhaust gases from various reactors, stills and packaging stations in the Tin Plant Recovery Section. The unit simultaneously scrubs SnCl4 vapours, their hydrolysis product HCl, and SnO2 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 SnO2 precipitate is discharged with the spent scrubbing liquor and its valuable tin content recovered.
   
Borden Chemicals, Formaldehyde Plant
Engelhard, Metals Recovery Incinerator
This TURBOSCRUBBER® plant, which was commissioned in the winter of 1999, is designed to treat the vapours venting from several storage tanks, reactors and other process plant, both under normal operation and during peak conditions when transfer, filling and emptying operations are being carried out. The scrubbing liquid (water), having absorbed the gases, is handled within the existing site process and treatment systems. The high mass transfer rates uniquely generated by the TURBOSCRUBBER® system are able to give the very high removal efficiencies required for such a compact plant.
Engelhard’s metal recovery incineration plant was upgraded in 1997 and 1998 to improve combustion and pollution control. A TURBOSCRUBBER® system was installed in series with an existing venturi scrubber to reduce high fine particulate loadings up to 750 mg/m3 down below 10 mg/m3, absorb HCl, and to cool gases for efficient plume suppression. Additionally a sophisticated control system was designed and installed for flexible operation of this versatile plant.


TURBOPAK® Technology

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. TURBOPAK® technology lying at the heart of the TURBOSCRUBBER® design is protected by US Process Patent No. 5,588,986 and worldwide design/copyright for the TURBOPAK® Packings.
