fgd gypsum desulfurization

About this site

Flue gas desulfurization (FGD) gypsum removes 93.31% of fluoride from 109 mg/L to 7.3 mg/L. Fluoride can be efficiently removed at the optimum pH range of 5-11. Kinetics analysis indicates that the theoretical fluoride capacity at 1 g/L FGD gypsum is 96.9 mg/g.

3.2.2.3 Furnace sorbent injection systems. Another dry FGD technology that was developed in the 1970s and 1980s involves injection of limestone or hydrated lime into the upper furnace; this process is often called furnace sorbent injection, or FSI. The injected sorbent is collected along with the fly ash in the existing ESP or fabric filter.
