Industrial Plant, Paper Mill, Control Device, Apparatus and Method for Drying Drying-Stock

摘要

A method for drying drying-stock includes separating solvent-containing drying stock within a drying unit into a base material and a solvent with the aid of a first heat transfer medium that flows through a first circuit, where after the solvent has been taken up by the first heat transfer medium, the solvent is extracted from the heat transfer medium via heat energy (condensation), where the heat energy is transferred by a heat exchanger with the aid of an evaporation unit to a second circuit and made available to a second heat transfer medium, and where the heat energy is fed in a condensation unit of the heat pump back to the first circuit with the aid of a heat pump.
