Abstract

MéTODO PARA SEPARAR CONTAMINANTES DE POLIéSTER. A presente invenção é geralmente direcionada a um processo para a separação e a recuperação de poliéster de pós-consumidor de vários materiais contaminantes. A invenção pode ser utilizada para separar poliéster de pós-consumidor de vários contaminantes incluindo vidro, sujeira, papel, metal, cola, corante, e semelhantes. O processo descrito inclui vários estágios incluindo um estágio de preparação, no qual uma porção dos contaminantes pode ser removida do poliéster, bem como um estágio de reação, no qual uma porção do poliéster pode ser saponificada e os contaminantes podem ser fisicamente separados do poliéster. Em adição, durante o estágio de reação, certos contaminantes de separação dificil, tais como alumínio e poli(cloreto de vinila), podem reagir para uma forma mais facilmente separável do poliéster.METHOD FOR SEPARATING POLYESTER CONTAMINANTS. The present invention is generally directed to a process for the separation and recovery of post consumer polyester from various contaminant materials. The invention may be used to separate post consumer polyester from various contaminants including glass, dirt, paper, metal, glue, dye, and the like. The process described includes various stages including a preparation stage, in which a portion of the contaminants may be removed from the polyester, as well as a reaction stage, in which a portion of the polyester may be saponified and the contaminants may be physically separated from the polyester. In addition, during the reaction stage, certain difficultly separating contaminants, such as aluminum and polyvinyl chloride, may react to a more easily separable form of the polyester.
