Abstract
Gaseous mixture of chlorine dioxide and chlorine produced by reacting an inorganic acid with an aqueous solution of an alkali metal chlorate by controlled introduction of the inorganic acid into the aqueous solution of alkali metal chlorate. Inorganic acid passed through a volume of alkali metal chlorate flowing through a horizontal reactor in a plug flow regime results in an enhanced gaseous mixture of chlorine dioxide, chlorine and steam that can be withdrawn as a product stream.
Claims22
A method for producing a mixture of chlorine and chlorine dioxide comprising the steps of:
- introducing an aqueous solution of an alkali metal chlorate with an inorganic acid into a reactor, said alkali metal chlorate and said inorganic acid present in ratio such that substantially all of said alkali metal chlorate and said acid are consumed to produce gaseous chlorine and chlorine dioxide having a ratio of chlorine to chlorine dioxide >1 and steam in a gas head space of said reactor;
- and
- removing said gaseous chlorine, chlorine dioxide and steam from said reactor;
A method for producing a gaseous mixture of chlorine dioxide and chlorine comprising the steps of:
- establishing a volume of an inorganic acid in a reactor;
- introducing an aqueous solution of an alkali metal chlorate at several locations within said volume of said inorganic acid, said inorganic acid and said alkali metal chlorate present in a ratio wherein substantially all of said acid and said chlorate are consumed to produce gaseous chlorine and chlorine dioxide having a ratio of chlorine to chlorine dioxide >3 and steam in a gas head space of said reactor;
- and
- removing said gaseous product stream of chlorine, chloride dioxide and steam from said head space.
