Ducon mainly provides the following
types of Flue Gas Desulfurization Systems:
All Ducon Flue Gas Desulfurization systems are custom designed to
remove sulfur dioxide from flue gases using a variety of reagents, such as:
caustic, lime, limestone, ammonia, flyash, magnesium oxide, soda ash, sea
water or double alkali. Ducon can provide systems that recover sulfur,
sulfuric acid or make dry gypsum from waste product.
Ducon has supplied wet FGD systems on over 20,000 MW of combined
power plant capacity. Ducon FGD systems can achieve over 99% sulfur dioxide
removal efficiency. Ducon Flue Gas Desulfurization systems can also recover
up to 90% of oxidized mercury in the flue gas.
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 Flue Gas Desulfurization
systems, Ducon uses its proprietary two-fluid nozzle DRX-25 to atomize feed
slurry in the spray reactor. Ducon can also provide a Circulating Reactor
Dry FGD System suitable for applications of upto 3% sulfur coal and by
utilizing dry lime, it can provide upto 97% SO2 removal efficiency. 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 &
Ducon has the capability to provide a complete global turnkey
installations including effluent treatment systems.
