<p>Chlorine dioxide production is integrated with a pulp mill system. A gaseous mixture of chlorine dioxide and chlorine is formed in a chlorine dioxide generating zone, an aqueous solution of chlorine dioxide wherein no more than about 10% of the available chlorine of the aqueous solution is provided by chlorine and the remainder of the available chlorine is provided by the chlorine dioxide is formed from the gaseous mixture, the aqueous chlorine dioxide solution is used to bleach cellulosic fibrous material pulp, hydrogen chloride is formed by reaction between the chlorine separated from the mixture and hydrogen and the hydrogen chloride is forwarded to the chlorine dioxide generating zone for use in forming the gaseous mixture of chlorine dioxide and chlorine.</p> |
