Abstract

EL ACIDO SULFURICO SE RECUPERA A PARTIR DE ACIDOS DILUIDOS (17) QUE CONTIENEN SULFATOS METALICOS, POR CONCENTRACION EN EVAPORADORES DE VACIO (1,4,7) Y SEPARACION DE LOS SULFATOS METALICOS DE LAS SUSPENSIONES (32) PRODUCIDAS AL EVAPORAR. EN ESTE PROCESO, LOS VAPORES (34) QUE SALEN DE LOS EVAPORADORES (1,4,7) Y QUE CONTIENEN ACIDO SULFURICO, CON CONTENIDOS DE SULFATOS METALICOS Y SULFATOS METALICOS SOLIDOS, SON CONDENSADOS POR CONTACTO DIRECTO CON ACIDO SULFURICO Y CON EL CONDENSADO DE VAPORES (10) QUE CONTIENEN ACIDO SULFURICO CON SULFATOS METALICOS EN DISOLUCION. LA REFRIGERACION DE ESTE CONDENSADO DE VAPORES (37) QUE, CIRCULANDO EN CIRCUITO CERRADO, SE UTILIZA COMO MEDIO DE REGRIGERACION, TIENE LUGAR POR EVAPORACION DE AGUA EN UN EVAPORADOR DE FLASH (12) AL TIEMPO QUE SE CONCENTRA EL ACIDO SULFURICO Y LOS SULFUROS METALICOS. PREFERENTEMENTE, LOS VAPORES CONCENTRADOS (37), CON UN CONTENIDO DE ACIDO SULFURICO DEL 1 AL 30 % EN PESO, SE SEPARAN DEL CIRCUITO DE REFRIGERACION, SIENDO LLEVADOS DENUEVO A LOS EVAPORADORES (1,4,7).
