Patent ID: 8609594

Claim:
A method for generating chlorine dioxide, said method comprising the steps of: a) providing a single vessel; b) blending or mixing an oxy halide salt with an acid within the single vessel to form a pre-mixed composition, wherein the acid comprises a weak acid in the range of about 5% to about 20%, more preferably about 5% to about 10%, or a strong acid in the range of about 0.1% to about 2%, more preferably about 0.2% to about 0.5%; c) maintaining within said vessel a temperature below about 100° F, an absence of a reducing agent, or both, wherein; said pre-mixed composition is stable within the vessel and does not convert to a halide oxide; d) dispensing the premixed, stable composition from the single vessel; and e) introducing said pre-mixed, stable composition into a reaction zone under conditions in which all or a part of the oxy halide salt is converted into chlorine dioxide, wherein the anion component of the oxy halide salt comprises chlorate, and said conditions in the reaction zone comprise the presence of one or more reducing agents and a temperature greater than about 110° F.
