Commercial Development Of The Advacate Process For Flue Gas Desulfurization

Commercialization of the ADVACATE process for flue gas SO/sub 2/ removal follows several years of bench-scale sorbent development pilot plant process optimization and field pilot evaluation. Results are presented showing the importance of silica dissolution in preparation of calcium silicates. Pilot and field optimization and evaluation shows excellent potential for over 90 percent SO/sub 2/ control at half the cost of conventional wet flue gas desulfurinzation (FGD) processes. Projected costs and commercialization plans are presented.
