Abstract
MÉTODO PARA RECICLAR UM RESÍDUO PLÁSTICO, E, USO DE FINOS SECOS CONTENDO TEREFTALATO DE POLIETILENO. Processos e instalações para usar um ou mais materiais contendo PET como uma matéria-prima para uma instalação de reciclagem química e, em particular, uma instalação de solvólise, são providos neste documento. Os materiais contendo PET usados como matéria-prima podem compreender uma quantidade de finos secos contendo PET. Os finos secos contendo PET podem ser derivados de vários processos e instalações, incluindo instalações de recuperação de PET e/ou fabricantes de artigos de PET. Por exemplo, os finos secos podem ser coletados de separadores sólido-líquido e/ou coletores de pó a partir de processos que incluem transporte, secagem, densificação, processos de centrifugação e/ou trituração de material plástico contendo PET. Tais finos secos são geralmente indesejáveis ou inutilizáveis para instalações de reciclagem mecânica de PET e normalmente são enviados para aterros sanitários /ou incineradores. No entanto, os processos e instalações aqui descritos fazem uso do PET e outros plásticos presentes nesses finos secos indesejáveis ou inutilizáveis.
