Dry Spray Absorption Technology for Flue Gas Desulphurization (FGD)

In spray absorption system, untreated flue gas is introduced into a spray dryer absorber module and contacts with a fine spray of lime slurry/reagent. The pollutants SO2, SO3, HCI and HF are rapidly absorbed, converted into the reaction products and removed by the downstream particle collector (fabric filter or electrostatic precipitator).
The dry spray absorption technology introduced by Insigma features low capital investment, low O&M cost, low auxiliary power consumption, less space requirement, simple structure and high availability. This technology is mature enough that numerous absorbers have been installed and successfully operated in the power stations worldwide.
