description In a process for increasing the sulfuric acid concentration of 90-98 wt % sulfuric acid, comprising stripping water from the sulfuric acid by contacting it with hot stripping media in a sulfuric acid concentrator column to increase the concentration of the acid leaving the column, the concentration of the acid is increased further by recycling a fraction of the acid, which is leaving the column, through an acid recirculation loop back to the inlet of the column, and the acid is optionally heated during its passage through the acid recirculation loop.
