Abstract

Se produce dióxido de cloro para la planta blanqueadora de un molino de pulpa de celulosa concentrando (evaporando) los efluentes líquidos de la planta blanqueadora a un nivel de concentración lo suficientemente alto para incineración, incinerando los efluentes concentrados para producir una ceniza, haciendo reaccionar químicamente cuando menos una parte de las cenizas para producir clorato, y utilizando el clorato de fabricación de dióxido de cloro. Las cenizas se purifican para producir cloruro de sodio y el cloruro de sodio se hace reaccionar con oxígeno y energía externa para producir clorato de sodio. Entonces, el clorato se utiliza en la fabricación de dióxido de cloro. Los sulfatos producidos se utilizan para fabricar ácidos y/o cáusticos, y se desechan hidróxidos de metales pesados. Una parte de las cenizas se puede utilizar directamente en la fabricación de dióxido de cloro. Cuando menos una parte de la sal de la fabricación del clorato se puede alimentar al ciclo de retorno de recuperación química, incluyendo una caldera de recuperación en el molino de pulpa. Los gases evaporados se pueden regresar al molino de pulpa y a la planta blanqueadora.
