Abstract

Se proporciona un metodo para purificar polietileno recuperado. El metodo implica obtener polietileno recuperado, poniendolo en contacto con un primer solvente fluido para producir un polietileno recuperado extraido, disolviendo el polietileno recuperado extraido en un solvente para producir una primera solucion que comprende polietileno y contaminantes suspendidos. La primera solucion se coloca para producir una segunda solucion que comprende polietileno y contaminantes restantes. La segunda solucion se purifica al poner en contacto la segunda solución con medio solidos para producir una tercera solucion que comprende polietileno mas puro. Finalmente, el polietileno mas puro se separa de la tercera solucion.
