Abstract
SE DESCRIBE UN METODO PARA LA CONCENTRACION DE ACIDOS FLUIDOS (4) EN UNA INSTALACION DE VAPORIZADOR CON UNA CIRCULACION FORZOSA DE VACIO EN TRES FASES, EN EL QUE SE CONDUCE EL ACIDO FLUIDO DE LA PRIMERA FASE Y DESDE LA TERCERA FASE (3) SE CONDUCE UN ACIDO SULFURICO RECONCENTRADO (7) CON LO QUE EL VAPOR DE AGUA (5) Y/O EL VAPOR DESPRENDIDO (6) SE UTILIZA COMO CEDIO DE CALEFACCION. ESTE METODO SE CARACTERIZA ADEMAS POR CONDUCIRSE CONTINUAMENTE DEL 30 AL 95% DE ACIDOS FLUIDOS (4) AL DEPOSITO EVAPORADOR (1B) DEL PRIMER NIVEL (1) Y LA CANTIDAD RESTANTE DEL ACIDO FLUIDO AL DEPOSITO EVAPORADOR (2B) DEL SEGUNDO NIVEL (2). CON ESTE METODO SE DISMINUYE FUERTEMENTE LOS RESIDUOS DE YESO EN EL PRIMER NIVEL.
