It is important to consider this question both in light of the recent large increase in knowledge of FGD technologies and also with .

Flue Gas Desulfurization Technologies for Coal-Fired Power ,

A variation of LSFO FGD systems used by a few utili-ties is the inhibited oxidation system In this process, emulsified sulfur or sodium thiosulfate is added to the scrubber liquor to prevent oxidation to calcium sulfate, thus acting as a scale control agent With low oxidation levels, the growth of larger calcium sulfite crystals pro-
