Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA PRODUCCION CONTINUA DE DIOXIDO DE CLORO QUE CONSISTE EN HACER REACCIONAR UN CLORATO DE METALES ALCALINOS, ACIDO SULFURICO Y CUALQUIER OTRO ACIDO MINERAL SIN CLORO Y PEROXIDO DE HIDROGENO COMO AGENTE REDUCTOR PARA PRODUCIR DIOXIDO DE CLORO EN UN MEDIO DE REACCION ACUOSO. EL DIOXIDO DE CLORO SE GENERA EN AL MENOS UN PASO DE REACCION QUE COMPRENDE UN RECIPIENTE DE REACCION POR LO MENOS, A BASE DE ALIMENTAR CLORATO DE METALES ALCALINOS, ACIDO, PEROXIDO DE HIDROGENO Y GAS INERTE EN DICHO RECIPIENTE DE REACCION, EN AUSENCIA SUSTANCIALMENTE DE IONES DE CLORURO AÑADIDOS, MANTENER EL MEDIO DE REACCION ACUOSO EN DICHO RECIPIENTE DE REACCION A UNA PRESION ENTRE 400 MM HG APROXIMADAMENTE Y 900 MM HG APROXIMADAMENTE Y A UNA TEMPERATURA ENTRE 35 (GRADOS) C APROXIMADAMENTE Y 100 (GRADOS) C APROXIMADAMENTE Y A UNA ACIDEZ ENTRE 4 APROXIMADAMENTE Y 14 N APROXIMADAMENTE Y LA CONCENTRACION DE CLORATO ENTRE 0,05 MOLES/L APROXIMADAMENTE HASTA LA SATURACION, RETIRAR ELDIOXIDO DE CLORO, EL OXIGENO Y EL GAS INERTE Y EL MEDIO DE REACCION ACUOSO AGOTADO DE DICHA ZONA DE REACCION SIN QUE SE PRODUZCA UNA CRISTALIZACION SUSTANCIAL DEL SULFATO DE METALES ALCALINOS.
