Who's Ducon

Example frontpage image Depending upon the reagent utilized, Ducon can select a packed tower, a spray tower or a Ventri-Rod Absorber (VRA™) (a proprietary Environeering unit) for the wet FGD application.

For Dry FGD systems, Ducon uses its proprietary two-fluid nozzle DRX-25 to atomize feed slurry in the spray reactor. Ducon provides either bag house filter or Electrostatic Precipitator for duct collection downstream. Ducon works with reputable vendors to provide Gas-to-Gas heat exchangers, fans, controls, and reagent handling & feeding systems.

Ducon has the capability to provide a complete turnkey installation including effluent treatment systems.
