| titleOfInvention | Procedure and device for reducing the content of polyester granulate acetaldehyde |
| abstract | Procedure for the preparation of a granulate with low acetaldehyde content from a highly viscous polyester melt with a V.I. between 0.60 and 1.0 dl / g, characterized in that a) the molten polyester bar is fractionated under water at a temperature of at least 90 ° C, b) the accompanying water is separated from the granulate with the least possible cooling of the granulate , so that the granulate present after the separation of the water at a temperature of at least 130 ° C, c) the water-poor granulate thus obtained after the separation of the water is added to a desaldehydration vessel, and d) the granulate in the Desaldehydration vessel is treated by a stream of washing air with an inlet temperature between 180 ° C and 200 ° C, the residence time of the granulate in the desaldehydration part of the vessel increasing to 3 to 20 hours; and the granulate being added in step c) either directly to the desaldehydration vessel or by adding a dosage unit, preferably a cell wheel lock, to the desaldehydration vessel. |
