Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA REGENERACION DEL ACIDO SULFURICO. CONSISTE EN CONCENTRAR PRIMERAMENTE EL ACIDO EN UNA UNIDAD DE CONCENTRACION PREVIA DE DOS ETAPAS CALENTADA INDIRECTAMENTE, OBTENIENDOSE UNA CONCENTRACION DE SALIDA. A CONTINUACION, EL ACIDO SE CONDUCE A UNA UNIDAD DE ALTA CONCENTRACION, DONDE SE SOMETE A UNA TEMPERATURA COMPRENDIDA ENTRE 160 Y 250 GRADOS Y A UNA PRESION COMPRENDIDA ENTRE 30 Y 100 TORR, OBTENIENDOSE UNA CONCENTRACION DE UN 90 A UN 98,3 POR 100 EN PESO DE H2SO4. POR ULTIMO, EL ACIDO SE PASA A UNA ETAPA DE PURIFICACION, DONDE A PRESION ATMOSFERICA O MAS REDUCIDA Y A UNA TEMPERATURA COMPRENDIDA ENTRE 220 Y 350 GRADOS, EL ACIDO SE PURIFICA. EL DISPOSITIVO SE CARACTERIZA PORQUE EN LA PRIMERA ETAPA DE CONCENTRACION PREVIA LLEVA UN INTERCAMBIADOR DE CALOR, FORMADO POR UN HAZ DE TUBOS DE TANTALO, CONECTADO CON UN DEPOSITO DE VAPOR DE SALIDA, EN LA SEGUNDA ETAPA DE CONCENTRACION PREVIA LLEVA UN INTERCAMBIADOR DE CALOR, FORMADO POR TUBOS DE ACERO REVESTIDOS DE ESMALTE, CONECTADO CON UN DEPOSITO DE VAPOR DE SALIDA; EN LA ETAPA DE CONCENTRACION LLEVA UN INTERCAMBIADOR DE CALOR; Y EN LA ETAPA DE PURIFICACION LLEVA UN TUBO DE CRISTAL DE CUARZO CALENTADO POR RADIACION, UN DISPOSITIVO DE CALENTAMIENTO PARA CALENTAR EL ACIDO, UNA ZONA DE REACCION Y UNA ZONA DE REACCION ULTERIOR.
