Brick and tile manufacturers must comply with MACT requirements for
HF, HCl, SO2, and dust emissions on their kiln exhausts.
Fisher-Klosterman was approached by a leading supplier in the industry
to make recommendations and offer a proposal to clean the kiln exhausts
at three of their plants. Though the technology had not been used on
this process before, wet scrubber / absorber systems were designed,
proposed, and installed. Each system supplied included a quench section,
a packed tower section, ductwork, an exhaust fan, pumps, piping and
valves, instrumentation, a control panel with starters, a stack with
platform and ladder, a make-up water tank package, a bleed tank package,
and a caustic tank package. Materials of construction included FRP,
CPVC, and alloy C276. The first of the stack emissions tests proved that
wet scrubbing technology is the solution for the brick and tile
industry. The removal efficiencies achieved are much higher than
traditional dry scrubbers and are more economical.
