Abstract

DONDE EL PROCESO COMPRENDE CONTINUAMENTE: a) ALIMENTAR A UN REACTOR UN ACIDO, UN AGENTE DE REDUCCION Y UN CLORATO DE METAL ALCALINO; b) HACER REACCIONAR EL CLORATO CON EL ACIDO Y EL AGENTE PARA FORMAR UN FLUJO DE PRODUCTOS QUE CONTIENE DIOXIDO DE CLORO Y SAL DE METAL ALCALINO DEL ACIDO; Y, c) LLEVAR DICHO FLUJO DESDE EL REACTOR A UNA TORRE DE ABSORCION, DONDE ES CONTACTADO CON UN FLUJO DE AGUA PARA FORMAR UNA SOLUCION ACUOSA QUE CONTIENE DIOXIDO DE CLORO EN UNA CONCENTRACION DE 4 A 12 g/L QUE SE MANTIENE CONSTANTE POR AJUSTE DEL FLUJO DE AGUA A LA TORRE, SIENDO RETIRADO DE LA TORRE EL GAS NO ABSORBIDO POR UN EDUCTOR, CREANDO UNA PRESION SUB-ATMOSFERICA EN EL REACTOR Y EN LA TORRE. EL REACTOR OPERA A UNA PRESION ENTRE 30 Y 100 KPa. EL pH DE LA SOLUCION ACUOSA ES DE 0,1 A 1. EL ACIDO ES ACIDO SULFURICO Y EL AGENTE DE REDUCCION ES PEROXIDO DE HIDROGENO
