Abstract
POLYMER GRANULES COMING FROM A POLYCONDENSATION PLANT (1) ARE AT LEAST PARTIALLY CRYSTALLISED AND IN A POSTCONDENSATION ARE BROUGHT IN DIRECT CONTACT WITH A NITROGEN-CONTAINING TREATMENT GAS. IN THE POSTCONDENSATION, THE TEMPERATURE OF THE POLYMER GRANULES IS INCREASED TO 175 AND 250°C AS COMPARED TO THE TEMPERATURE OF THE GRANULES COMING FROM THE POLYCONDENSATION PLANT (1). NITROGEN-CONTAINING EXHAUST GAS FROM THE POLYCONDENSATION PLANT (1) IS ADMIXED TO THE TREATMENT GAS IN A VOLUME RATIO FROM 1: 1 TO 1: 1 000, BEFORE IT IS INTRODUCED INTO THE POSTCONDENSATION.(FIG 1)
