Present Situation and Perspectives of CCP Management …
In dry and semidry desulphurization processes 0.49 million tonnes of SDA product (spray dry absorption product) and in wet FGD approximately 11.3 million tonnes of FGD gypsum (flue gas desulphurization gypsum) were produced in 2003. A decrease in utilization of the SDA product down to about 19 %, only, compared to 40 % in 2002 took place.
