Process for subsequent condensation of polycondensates, in particular of polyamide 6.6 |
| abstract |
The invention relates to a process for one-stage subsequent condensation of polycondensates, in particular of polyamide 6.6 granules in a fluidised bed reactor (1). During said process, a partial stream of a carrier gas, where nitrogen (N2) is used as the carrier gas, is removed at a temperature of 20-230 DEG C from the main stream and is conveyed in such a manner through a gas washing column (15) charged with water that the partial stream of conditioned carrier gas is returned with a point of condensation of 10-80 DEG C (100 % of relative humidity) into the main stream of the carrier gas. During the cooling phase of the granules, return of the partial stream of carrier gas is stopped. After cooling, the granules are removed and used directly in other applications. Said process achieves the designated viscosity and also a precisely defined level of humidity in the polymer, which level is important for further processing. |
