Abstract

PROCESO PARA LA LIMPIEZA DURANTE PERIODOS INACTIVOS DE SUPERFICIES METALICAS INTERNAS, POR EJEMPLO DE HIERRO O ACERO, DE EQUIPOS UTILIZADOS EN LA INDUSTRIA QUIMICA, EN VIRTUD DEL CUAL UN FLUIDO LIMPIADOR QUE CONTIENE AGUA, UN ACIDO Y UN INHIBIDOR DE LA CORROSION SE BOMBEAN HACIA EL INTERIOR DEL EQUIPO CON UN INTERVALO DE AL MENOS 0,5 M/S, PARA QUE EL FLUIDO PASE A TRAVES DEL FILTRO DE REDUCCION (1) SITUADO EN EL EXTERIOR DEL EQUIPO; EL FILTRO (1) CONTIENE UN CONJUNTO SUSTANCIALMENTE METALICO CON LA MAYOR RELACION DE SUPERFICIE-PESO QUE SEA POSIBLE; LA COMPOSICION DEL FLUIDO SE CONTROLA DURANTE LA OPERACION CON LA MEDIDA DEL POTENCIAL DE REDUCCION-OXIDACION, QUE SE MANTIENE POR DEBAJO DE UN VALOR LIMITE Y QUE ACUMULA CERCA DE 280 MV O MENOS, CUANDO LA MEDICION SE REALICE CON UN ELECTRODO DE PLATINO FRENTE A UN ELECTRODO SATURADO DE CALOMELANOS KCI.
