Method for treating halogenated hydrocarbons prior to hydrothermal oxidation

摘要

A method for pretreating a halogenated hydrocarbon feed to a hydrothermal oxidation reactor which includes forming a combination of a halogenated hydrocarbon with added alkali under hydrothermal conditions, adding water to the combination, thereby effectuating hydrolysis of the halogenated hydrocarbon so as to liberate halogen ions which are neutralized by the alkali. The neutralized halogen ion, a salt, may be removed from the process prior to or during the oxidation step as brine droplets.
