Abstract

UN PROCESO PARA LA PRODUCCION DE DIOXIDO DE CLORO QUE ESTA LIBRE SUSTANCIALMENTE DE UN SUBPRODUCTO DE CLORO. EL DIOXIDO DE CLORO SE PRODUCE A PARTIR DE UN CLORATO DE METAL ALCALINO, UN ACIDO MINERAL Y UN AGENTE REDUCTOR COMO POR EJEMPLO METANOL EN UN MEDIO DE REACCION MANTENIDA A UNA NORMALIDAD ACIDA MENOR DE 9 Y CON UNA ALTA MOLARIDAD DE CLORO. EL PROCESO SE LLEVA A CABO ANTE LA AUSENCIA SUSTANCIAL DE UN ION DE CLORURO ADICIONAL SIENDO ALIMENTADO AL PROCESO. SE HA DESCUBIERTO QUE SI SE AUMENTA LA CONCENTRACION DE CLORATO A UNA NORMALIDAD ACIDA DADA SE REDUCE LA CANTIDAD DE CLORURO EN EL MEDIO DE REACCION REDUCIENDO ASI LA CANTIDAD DE SUBPRODUCTO DE CLORO. EL PROCESO SE LLEVA A CABO EN UN RECIPIENTE SOMETIDO A PRESION SUBATMOSFERICA, POR DONDE SE EVAPORA Y RETIRA EL AGUA JUNTO CON DIOXIDO DE CLORO Y LA SAL DE METAL ALCALINO DEL ACIDO MINERAL SE CRISTALIZA DENTRO DEL RECIPIENTE DE REACCION Y SE RETIRA DEL MISMO. SEGUN LA INVENCION, SE PUEDEN LOGRAR ALTOS INDICES DE PRODUCCION DE GRAN EFICACIA AL TIEMPO QUE SE PRODUCE UN SUBPRODUCTO SIN CLORO.
