Ducon Technologies Inc. products

Ducon`s Selective Catalytic Reduction (SCR) DeNOx, and CO removal Systems features state of the art catalyst technology and controls engineering for easy erection and quick tie-in to new or existing Power Plant. Ducon DeNOx Catalyst is manufactured in China and has been proven in numerous power plant installations including installations in 1000 MW power plants with NOx removal efficiency of 98%.

Ducon supplies Semi-Dry Removal (SDR) type Dry Flue Gas Desulfurization (FGD) Systems as well as Dry Injection type systems. The SDR systems are custom designed to absorb gaseous pollutants utilizing a spray dryer and a baghouse filter. Ducon`s specially designed air atomizing nozzles provide the liquid reagent slurry into the spray dryer for high efficiency removal of SO2, HCl, Mercury and other toxic components from flue gases. Ducon`s SDR system provides very high on-line availability and low maintenance as compared to a rotary atomizer type of system.

Ducon Multicyclones have been providing exceptional service for the past 50 years in an extensive variety of applications. Ducon Multitube Cyclone Collectors are designed for high efficiency and low pressure drop, so that maximum particulate is collected at minimum operating costs. The simple, sturdy construction of tubes assures long,service life with nil down time and minimal maintenance. Ducon Multicyclones have no moving parts and are custom designed for a wide range of gas flows and inlet loadings.

Ducon supplies Dry & Wet Electrostatic Precipitators for new applications, upgrade of existing installations and replacement parts. Ducon has operating installations at boilers of sizes up to 600 MW capacity.In many cases, Wet Precipitators are being used in coal fired power plants to control acid mist emissions after a WFGD.

Ducon Carbon Absorbers are custom designed to remove odor-causing components such as hydrogen sulfide, mercaptans, organic acids, aldeheydes, and ketones in various industrial and municipal applications. Single bed units are available for capacities up to 10,000 acfm.Dual bed units are utilized for higher capacities. Ducon can also provide systems that regenerate the carbon via steam or chemicals thus eliminating the need for disposal.

Fluid Catalytic Cracking (FCC) is one of the most important refinery processes as it converts high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils to more valuable gasoline, olefinic gases, and other products. Residue fluid catalytic cracking (RFCC) is used for upgrading heavy feedstocks to light products. Therefore, a properly designed and highly efficient FCC & RFCC cyclone system is extremely important to ensure refineries operate efficienctly with reduced operating costs and remain competitive.

TYPE UW-4 This Ducon Patented UW-4 Scrubber is used for particulate control and is a maintenance free unit, complete with integral wet fan, achieving high efficiency with medium pressure drop in applications involving heavy dust loads, and abrasive materials.

This Ducon unit features a wetted wall inlet which eliminates wet-dry line build-up and permits direct recycle of high-solids liquid. Scrubbing liquid is distributed over a weir or shelf - no spray nozzles are used. The Venturi is teamed with a mist eliminator for efficient entrainment separation.
