Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA OBTENER O RECUPERAR ACIDOS A PARTIR DE SOLUCIONES, EN PARTICULAR SOLUCIONES QUE CONTIENEN SALES METALICAS, SE SEPARAN ESTOS ACIDOS MEDIANTE ENRIADO POR PULVERIZACION DE LAS SOLUCIONES. SE CARACTERIZA PORQUE EL ENRIADO POR PULVERIZACION SE REALIZA CON POCO TIEMPO DE REPOSO Y DESPUES SE REALIZA OTRO ENRIADO CON TIEMPO DE REPOSO MAS LARGO. LA INVENCION TRATA TAMBIEN DE UNA INSTALACION PARA LLEVAR A CABO EL PROCEDIMIENTO, EN LA CUAL SE PREVE EN EL ENRIADOR DE PULVERIZACION 1 UNA ZONA 4 SEPARADA DE EL PARA EL ENRIADO POSTERIOR.
