An apparatus having a honeycomb rotor for adsorbing solvent in to-be-treated gas that is supplied to the rotor, which rotor also receives a supply of regenerating water vapor, wherein the water vapor is laden with the solvent after desorption of the solvent takes place, the water vapor mixture being then condensed. A seal structure is provided between the rotor and a housing to divide the interior of the housing into a plurality of regions, the seal allowing the rotor to rotate. The gas to be treated and reactivating water vapor are supplied to one of the regions at different positions in the direction of rotation of the rotor, whereby continuous and high speed treatment can be performed. The water vapor mixture which is not condensed, along with gases used to dry the rotor, are combined with the to-be-treated gas.
