Abstract

Se proporcionan en la presente procesos e instalaciones para utilizar uno o más materiales que contienen PET como un material de alimentación a una instalación de reciclaje químico, y en particular una instalación de solvólisis. Los materiales que contienen PET utilizados como material de alimentación pueden comprender una cantidad de finos secos que contienen PET. Los finos secos que contienen PET se pueden derivar de varios procesos e instalaciones, que incluyen instalaciones de recuperación de PET y/o fabricantes de artículos de PET. Por ejemplo, los finos secos se pueden recolectar de separadores de sólido-líquido y/o recolectores de polvo de los procesos que incluyen procesos de transporte, secado, densificación, centrifugación y/o molienda de material de plástico que contiene PET. Tales finos secos son generalmente indeseables o no utilizables para las instalaciones de reciclaje de PET mecánico, y típicamente se envían a rellenos sanitarios y/o incineradores. Sin embargo, los procesos e instalaciones descritos en la presente hacen uso del PET y otros plásticos presentes en estos finos secos de otra manera indeseables o no utilizables.
