Sulfuric acid is used more often than HCl acid. One reason for this is because sulfuric acid is relatively lower in operating cost than HCl acid. Another advantage to using sulfuric over HCl is the reduced fuming to the atmosphere,which means less corrosion to surrounding metal components.Sulfuric acid is sometimes preferred over HCl since there is a better membrane rejection of the sulfate ion than the chloride ion.
