ABSTRACT:
The arrangement for the drying of solvent at a drying channel with a hot inert carrier medium, under application of compression and adiabatic expansion for the condensation of the solvent, and under reheating of the solvent to the channel temperature is provided in such a manner that a heat exchanger is arranged to follow a compressor for the nitrogen, containing solvent vapor, taken from the drying channel, which heat exchanger is passed through by the carrier medium, drawn from the drying channel and flowing through a pipeline loop, that a condenser arranged follows the compressor for the solvent vapor, on the one hand, feeds the expansion stage, and, on the other hand, is cooled by the nitrogen, cooled in the expansion stage, same being heated to the channel temperature, and that the heated nitrogen is fed into the drying channel. Thereby an energy application as economical as possible in the drying channel is achieved, under general avoidance of external heating.
