ABSTRACT:
Cooling process for polyester and/or polyamide resins downstream of solid-state polycondensation plants in which the cooling is carried out by passing the solid material through two types of equipment in series, of which one is a fluid-bed, the other is a solid/wall cooling equipment. The fluid bed equipment is fed with a stream of inert-gas coming from the solid-state polycondensation reactor, previously subjected to by-products purification, drying and cooling.
