Abstract:
1. A method of generating a chlorine dioxide solution comprising: (a) generating chlorine dioxide gas in a chlorine dioxide gas source having an anolyte loop at least partially comprising an electrochemical cell operating at a current greater than 120 A; (b) effecting dissolution of said chlorine dioxide gas into a liquid stream to form a chlorine dioxide solution in an absorption loop fluidly connected to said chlorine dioxide gas source; and (c) operating a cooling system within said absorption loop to cool said chlorine dioxide solution, said cooling system further comprises at least one water flush injector fluidly connected before a gas transfer pump, said gas transfer pump located within said absorption loop and after said chlorine dioxide gas source; (d) adding water from the at least one water flush injector at intermittent intervals to cool said chlorine dioxide gas to a temperature of less than 130° F. (54.4° C.).
