Sulfuric acid magnesium salt (1:1) → Calcium Sulfate

Participants

Reaction Steps

In the reactor tank, the soluble magnesium sulfate reacted with the calcium hydroxide to produce magnesium hydroxide and calcium sulfate, both of low solubility. The effluent from the reactor tank was pumped to the recycle tank at a rate of about 2.5 gpm. Conveniently, the addition of the hydrated dolomitic lime and hydrated lime may be followed by the pH of the mixture in the reactor tank, with the pH in the reactor tank varying between 9 and 10, which provides a pH in the recycle tank of between about 6 and 7.
