Abstract

Polimero granulado que llega desde una planta de policondensacion, se cristaliza al menos parcialmente y se lleva en contacto directo durante una condensacion posterior con un gas de tratamiento con nitrogeno; a este respecto la temperatura del polimero granulado en la condensacion se aumenta frente al granulado que llega desde la planta de policondensacion a una temperatura de entre 175 y 250 degree C.; gas de salida con nitrogeno desde la planta de policondensacion se agrega al gas de tratamiento en un relacion de volumen de 1:1 a 1:1000, antes de que se le conduzca a la condensacion posterior.
