AIR QUALITY CONTROL SYSTEM(AQCS)
Seawater flue gas desulfurization (FGD) is an attractive solution for power plants loed in coastal areas. By applying this technology, we can reach high desulphurization performance similar to Wet limestone FGD. Moreover, the Seawater FGD is more costeffective due to its less complex process and does not create any waste.
