Abstract
A process and apparatus for the manufacture of chloride-free hypochlorous acid using hydrolyzing of chlorine with steam and water vapor, solid-gas stripping of the co-generated hydrochloric acid vapor in a fluidized bed reactor, equilibrium discharge of chloride particulate from the bed of the reactor, selective dissolving of the hypochlorous acid vapor into aqueous product solution in a packed bed absorber, and closed-loop recycling of the stripped product stream.
