Abstract

Настоящее изобретение вообще направлено на процесс для отделения бывшего в употреблении полиэфира от различных загрязняющих его материалов и извлечения полиэфира. Изобретение может быть использовано для отделения бывшего в употреблении полиэфира от различных загрязнений, включая стекло, грязь, бумагу, металл, клей, краситель и т.п. Раскрытый процесс включает в себя несколько стадий, таких как стадия приготовления, в которой часть загрязнений может быть удалена из полиэфира, а также стадию проведения реакции, в которой часть полиэфира может быть омылена и загрязнения могут быть физически отделены от полиэфира. Помимо этого во время стадии проведения реакции некоторые трудно отделяемые загрязнения, такие как алюминий и поливинилхлорид, могут вступать в реакцию с образованием более легко отделяемой формы от полиэфира.
