Abstract
A process for recovering chlorine values from an aqueous solution of a chloroisocyanuric acid compound is disclosed. After reacting a mineral acid with the aqueous solution to form an acidified reaction mixture containing dissolved chlorine, the reaction mixture is fed to a stripping column which employs an inert gas to remove the dissolved chlorine. The stripping column is maintained to provide a continuous liquid phase and a non-continuous gas phase. Chlorine gas is readily recovered in a vessel such as a scrubber. Cyanuric acid may be subsequently recovered from the chlorine-depleted solution.
