Design of lime/limestone flue gas desulfurization systems ...

Abstract. This paper summarizes C-E experience regarding the impact of chlorides on flue gas desulfurization system (FGDS) design. The effect of chloride on alloy selection, SO/sub 2/ absorption, scale control, and additives use as well as techniques that may be used to limit chloride concentration in lime/limestone FGD systems are discussed.

Dry Flue Gas Desulfurisation Technology

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.
