| titleOfInvention | Method of producing chlorine dioxide |
| abstract | The invention relates to a process of producing chlorine dioxide comprising the steps of reducing chlorate ions in an acid reaction medium maintained in a reaction zone of a chlorine dioxide generator, which reaction medium contains alkali metal ions and sulfate ions, so to form chlorine dioxide and a solid salt of acidic alkali metal sulfate. The process further comprises the steps of separating said solid acidic alkali metal sulfate from the reaction medium, contact-ing said solid acidic alkali metal sulfate with an acid aqueous medium in a mixing tank to effect at least partial conversion to neutral solid alkali metal sulfate, separating the at least partially neutralized solid alkali metal sulfate from the acid aqueous medium on a filter and forming an acid filtrate, feeding at least a portion of said acid filtrate to the mixing tank, and transferring an acid aqueous medium to the reaction zone of the chlorine dioxide generator, which acid aqueous medium is a portion of the acid filtrate or acid aqueous medium from the mixing tank or a mixture thereof. |
