Abstract

LA INVENCION DESCRIBE UN PROCEDIMIENTO PARA LA OBTENCION DE DIOXIDO DE CLORINA DONDE SON REACTIVADOS ACIDO SULFURICO Y UN AGENTE REDUCTOR CON ADICCION OPTATIVA EXTRA DE IONES DE CLORINA EN UN REACTOR PRIMARIO DE CLORATO, LA MEZCLA RESULTANTE DE GAS CONTENIENDO PRINCIPALMENTE DIOXIDO DE CLORINA Y AIRE SON INTRODUCIDOS A PRESION A TRAVES DE UN DISPOSITIVO HASTA UNA TORRE DE ABSORCION DEL GAS. DONDE LA DISOLUCION DEL REACTOR ES CONDUCIDA OPCIONALMENTE A UN REACTOR SECUNDARIO AL CUAL SE LE AÑADE TAMBIEN UN ELEMENTO REDUCTOR CARACTERIZANDOSE EL SISTEMA POR LA RECIRCULACION OPTATIVA DE ESA PARTE DE LA DISOLUCION DEL REACTOR PRIMARIO A TRAVES DE UN REFRIGERADOR HACIA LA PARTE SUPERIOR DE UN DEPURADOR Y CON RETORNO AL REACTOR.
