Abstract
La presente invención se refiere a un proceso para permitir el reciclaje de un flujo de material residual de poliéster mediante la despolimerización del poliéster por medio de alcoholisis, siendo que el proceso comprende al menos una primera etapa de despolimerización y una segunda etapa de despolimerización consecutiva separada, a cuyas etapas de despolimerización primera y segunda se somete de manera continua el flujo de material residual polimérico, siendo que en la primera etapa de las dos etapas consecutivas, el flujo del material residual de poliéster se alimenta de manera continua a una extrusora que trabaja a una temperatura superior a la temperatura de fusión del poliéster, en tanto que a la extrusora se le alimenta simultáneamente una primera cantidad de alcohol, con el fin de producir una mezcla fluida que comprende una masa fundida del poliéster al menos parcialmente despolimerizado y siendo que, en la segunda etapa, la mezcla fluida se alimenta de manera continua a un reactor de tanque de agitación contínua (CSTR) que trabaja a una temperatura por arriba de la temperatura de fusión del poliéster, en tanto que simultáneamente se alimenta una segunda cantidad de alcohol al CSTR, siendo que el tiempo de residencia en el CSTR se usa para proporcionar en la salida del CSTR un flujo contínuo de poliéster despolimerizado a un éster oligomérico. La invención también se refiere a un sistema para aplicar el método.
