Considerable energy savings may be realized by recovering heat from hot PET pellets exiting a solid state polymerization reactor, and using this heat to heat cool pellets entering the crystallizer or solid state polymerization reactor. The heat may be transferred from hot to cool pellets employing a heat exchanger.
