Title: Sulfur oxides control technology series: Flue-gas desulfurization. Dual alkali process. Summary report

The report describes a dual alkali (or double alkali) flue gas desulfurization (FGD), which is a throwaway process in which sulfur dioxide (SO2) is removed from the flue gas by a soluble sodium-based scrubbing liquor. The collected SO2 is precipitated as calcium sulfite (CaSO3), calcium sulfate (CaSO4), or a mixed crystal of both salts, and is purged from the system.
