Abstract (en)

In order to overcome the problems that earlier methods have experienced, a method for drying filter cake is proposed, comprising the steps of: a) feeding wet filter cake into at least one drier (E101); b) feeding drier gas into said drier (E101); c) recovering solvent-containing gas from said drier (E101); d) feeding said solvent-containing gas to at least one cryogenic condensation system (E102); e) feeding at least one inert gas to said cryogenic condensation system (E102); f) condensing solvent from said solvent-containing gas; g) recovering solvent-free gas from said cryogenic condensation system (E102); and h) feeding said solvent-free gas to said drier (E101).
