Abstract

MÉTODOS PARA PROCESSAR MATERIAIS DE POLÍMERO DE RESÍDUO E MATERIAIS POLIMÉRICOS DE RESÍDUO, E, COMPOSIÇÃO DE SOLVÓLISE. Instalações de reciclagem química para processar plástico de resíduo misto são providas no presente documento. Tais instalações têm a capacidade de processar correntes de resíduo plástico misto e utilizar uma variedade de instalações de reciclagem, como, por exemplo, instalação de solvólise, uma instalação de pirólise, uma instalação de craqueador, uma instalação de gaseificação de oxidação parcial, uma instalação de recuperação de energia e uma instalação de solidificação. As correntes a partir de uma ou mais dessas instalações individuais podem ser usadas como alimentação para uma ou mais das outras instalações, maximizando assim a recuperação de componentes químicos valiosos e minimizando as correntes de resíduo inutilizáveis.
