Abstract
The invention relates to a method for producing especially PET granulates, wherein terephthalic acid and ethylene glycol are fed in the form of a precondensate into a drip tower having a distributing drip nozzle after esterification and pre-polycondensation with the purpose of effecting granulation. The precondensate exits the distributing drip nozzle by forming drop-shaped pellets that are blown by a hot countercurrent nitrogen stream reducing the velocity of fall and accelerating crystallization at an increasing degree of crystallization. Dried, semi-crystallized round pellets are thus produced that are then subjected to solid phase polycondensation resulting in pellets possessing high viscosity and quality for further processing.
