Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO CONTINUO PARA RECUPERAR PARTICULAS DE POLIMERO DE UNA SOLUCION DE POLIMERO EVAPORANDO EL SOLVENTE DE LA SOLUCION TRATANDO SUCESIVAMENTE LA SOLUCION DENTRO DE UN PRIMER RECIPIENTE AGITADO (3) Y TRATANDO EL POLIMERO RESULTANTE DENTRO DE UN SEGUNDO RECIPIENTE AGITADO. ADEMAS, LA INVENCION SE REFIERE A UN APARATO (3,5,14,15,22) PARA REALIZAR EL PROCESO ANTEDICHO PARA RECUPERAR LAS PARTICULAS DE POLIMERO . EL APARATO COMPRENDE UN PRIMER RECIPIENTE AGITADO (3), UN SEGUNDO RECIPIENTE AGITADO Y UNA VALVULA DE DESCARGA DE ACCION RAPIDA (22) EN LA SALIDA DEL SEGUNDO RECIPIENTE AGITADO. EL PRIMER Y SEGUNDO RECIPIENTE AGITADO TIENEN ALABES MOVILES (5,15).
