Ducon's Selective Catalytic Reduction (SCR) NOx, N2O,
CO and VOC Reduction System features state of the art catalysis technology
and controls engineering for easy erection and quick tie-in to new or
existing process systems.
Ducon utilizes ceramic honeycomb shapes or plate-type catalysts consisting
of titanium dioxide as a base material with active coatings of vanadium
pentoxide and tungsten trioxide that have been arranged at different
levels. The working temperature of the catalyst ranges between 600 F and
800 F. For NOx systems Ducon provides Ammonia injection systems complete with
storage tanks, vaporizers and injection grids. Ducon can provide ammonia as
anhydrous or aqueous (19%, non-hazardous) solution. Ducon systems have low
ammonia slip.
For systems requiring heat, the burner features a FM approved gas train and
Honeywell Burner Management System. The units are designed for heat
recovery in the range of 65 - 75%. Ducon SCR systems can achieve over 90 %
NOx & N2O, 90% CO and high VOC removal efficiencies.
