7. In a limestone FGD scrubber, 15% of the slurry mass are solids, of which 11.6% is CaCO3. 1% of Caco, in the slurry is assumed to be reacted with SO2 in one pass through the scrubber. (a) Estimate how many mols/L of SO, are dissolved in the scrubbing slurry in one pass through the scrubber?
Test results show that adding adipic acid to the limestone slurry significantly improved the SO sub 2 removal efficiency of the FGD system. Limited baseline data on operations with limestone only indicated a performance level of 55% SO sub 2 removal. Adding about 2200 ppM of adipic acid to the limestone scrubbing systems, the …

----- SUMMARY FGD PROCESSES All commercial flue gas desulfurization (FGD) installations operating on U.S. coal-fired utility boilers are wet scrubbing processes that contact the flue gas with a water solution of soluble (or sparingly soluble) alkali to absorb the SCL. ... the removal efficiency of a lime or limestone FGD system can be substan ...
through FGD and sodium sulfite regenerable processes, respectively.2 Considering the relatively marginal applica-tion of regenerable FGD processes, this paper focuses only on once-through FGD processes. Accordingly, when wet FGD is mentioned in the remainder of this paper, it is meant to be once-through wet FGD. Similarly, when dry FGD is
Flue gas desulfurization is the most effective and leading method to control acid rain and SO2 pollution and limestone-gypsum FGD method is most matured until now. The simplified wet limestone-gypsum FGD system applied in Taiyuan Cogeneration Power Plant is introduced in detail in this article. Through the analysis of operation data …

Hydrated lime is normally used as SO 2 sorbent in spray dry scrubbers, whereas limestone is considered unreactive under conditions prevailing in such a system. However, limestone is more easily available and several times cheaper than hydrated lime. We tried to use limestone to remove SO 2 from flue gas in the semidry FGD process …
