Versuchsvorschrift

The solubilized calcium bisulfite in the scrubbing solution discharged from the low pH scrubbing stage may then readily be reacted with oxygen in solution to form a solution of calcium sulfate from which crystalline calciium sulfate dihydrate is precipitated. The generalized reactions for the solubilization of calcium sulfite are set forth in equations I and II, the reaction for the oxidation of the bisulfite is set forth in equation III and the reaction for the precipitation of crystalline calcium sulfate is set forth in equation IV.
