Abstract
A regeneration process and apparatus eliminates the need for an external chlorination recycle loop. The method and apparatus uses two-pass internal mixing of a chlorine compound input stream and drying gas to both mix and heat the chlorination gas before entering the chlorination zone. The only heat required for the process is a small amount for vaporizing the chlorine containing input stream to prevent the formation of chloride droplets. All other heat for the chlorination zone is supplied internally in the regeneration vessel.
