METHOD AND APPARATUS FOR SEPARATING POLYMER FROM A PLASTIC, AND THE RESULTING SEPARATED POLYMER

摘要

A method and apparatus for continuously separating polymer from a plastic, and the resulting separated polymer. The plastic is made flowable into a stream through melting or solubilizing. A critical fluid, such as supercritical carbon dioxide, is added to the plastic stream to promote mechanical or thermodynamic separation of the polymer from contaminants and other components of the plastic.
