Abstract

Se obtienen ahorros de energía durante la producción comercial de polietilen tereftalato enfriando parcialmente los pellets de polietilen tereftalato que salen de un reactor de polimerización de estado sólido mediante el contacto con agua y utilizando el calor residual almacenado en los pellets para valorizar el agua asociada para formar pellets secos.
