Abstract

A wet web (4) and a drying felt (5) are enclosed between two air-tight surfaces having a good thermal conductivity. The surface in contact with the web is heated and the surface in contact with the drying felt is cooled by cooling water so that water is evaporated from the web into the felt and condensated in the felt. After the condensation the felt is separated from the dry web. The cooling water is discharged from the drying process at a temperature of 60 DEG -100 DEG C so that the enthalpy of the discharged cooling water can be utilized economically e.g. for heat pumping. The discharge temperature of the cooling water is controlled by adjusting the inlet temperature and/or the flow rate of the cooling water supplied to the drying process. <IMAGE>
