Abstract

PROCEDIMIENTO PARA RECUPERAR POLIETILENO Y ALUMINIO DE HOJAS DE ALUMINIO RECUBIERTAS DE POLIETILENO DE RESIDUOS DE ENVASES TIPO ''PACK". EL PROCEDIMIENTO UTILIZA DISOLVENTES ORGANICOS TALES COMO HIDROCARBUROS CLORADOS O NO Y COMPRENDE LAS SIGUIENTES ETAPAS: A) TROCEADO DEL MATERIAL, B) EXTRACCION DEL POLIETILENO CON UN DISOLVENTE ORGANICO, C) SEPARACION EN CALIENTE DEL ALUMINIO DE LA SOLUCION OBTENIDA EN B), D) SEPARACION DEL POLIETILENO DISUELTO BIEN POR ENFRIAMIENTO, DE LA SOLUCION HASTA UNA TEMPERATURA INFERIOR A 60 C Y SEPARACION DEL SOLIDO QUE PRECIPITA, BIEN POR EVAPORACION DEL DISOLVENTE, EN EL QUE CUALQUIERA DE LAS ETAPAS B), C) Y D) SE LLEVAN A CABO DE FORMA CONTINUA O DISCONTINUA. COMO DISOLVENTES SE EMPLEAN HIDROCARBUROS ALCANOS, OLEFINICOS, AROMATICOS O MEZCLAS DE ELLOS E HIDROCARBUROS HALOGENADOS. LA EXTRACCION SE LLEVA A CABO A TEMPERATURAS ENTRE 50 Y 200 C, Y A UNA PRESION COMPRENDIDA ENTRE LA ATMOSFERICA Y 0,4 KPA.PROCEDURE FOR RETRIEVING POLYETHYLENE AND ALUMINUM FROM ALUMINUM SHEETS COVERED FROM POLYETHYLENE WASTE FROM 'PACK' TYPE PACKAGING. THE PROCEDURE USES ORGANIC SOLVENTS SUCH: POLYETHYLENE WITH AN ORGANIC SOLVENT, C) HOT SEPARATION OF THE ALUMINUM FROM THE SOLUTION OBTAINED IN B), D) SEPARATION OF THE SOLVED POLYETHYLENE WELL BY COOLING, UNTIL A TEMPERATURE LESS THAN 60 C AND SEPARATION OF THE SOLID WHICH PRECIPENTS, WELL BY EVAPORATION OF THE SOLVENT, IN WHICH ANY OF THE STAGES B), C) AND D) ARE CARRIED OUT CONTINUOUSLY OR DISCONTINUOUSLY. AS SOLVENTS, ALKAN HYDROCARBONS, AROMATIC OILS AND HYDRAULICS, AND HYDROCARBONS ARE USED. CAPE AT TEMPERATURES BETWEEN 50 AND 200 C, AND AT A PRESSURE INCLUDED BETWEEN THE ATMOSPHERIC AND 0.4 KPA.
