The scrubber purge stream—or FGD wastewater—is most often treated in a dedicated wastewater facility rather than a plant's existing wastewater treatment . are removed by adding the following: alkali, to allow gypsum to de-saturate; organo-sulfide, to further precipitate heavy metals; iron salts to help form a denser floc,.
However, in dry injection or spray drying operations, the SO 2 is first reacted with the lime, and then the flue gas passes through a particulate control device. Another important design consideration associated with wet FGD systems is that the flue gas exiting the absorber is saturated with water and still contains some SO 2.
Powder injection times for hot metal desulphurisation have been dramatically cut by up to 50% at Corus. Scunthorpe by the modernisation of the plant using Twinjection™ technology. Twinjection™ technology introduces two powder streams into the hot metal down a single refractory lance. Lower sulphur levels can now be.
