Abstract

In a process for mechanically dehumidifying a filter cake, differential pressure causes a treatment fluid to flow through the filter cake. Pressure and temperature on the side of the filter cake which faces the filter surface are set in such a manner that the treatment fluid is present there in its liquid phase, whereas pressure and temperature on the side of the filter cake opposite to the filter surface are set in such a manner that the treatment fluid is present on that side in its gaseous phase.
