A process for the purification of gases loaded in particular with chemical residues, in particular of the exhaust air from printing equipment, in which process the gas to be purified is drawn off from the regions producing the impurities and led via piping to an arrangement of adsorber-filter cartridges that serve for the separation of the impurities from the gas and are periodically separated in a cyclical manner from the exhaust flow for the carrying out of a regeneration process. The adsorber material is impinged upon by an expelling medium that is suitable for the cleansing or regeneration of the adsorber material; in addition to a number of adsorber-filter cartridges planned for the continuous carrying out of the purification process and running in the adsorber operation, provision is made for at least one additional adsorber-filter cartridge that is in the regeneration state in a cyclical exchange with in each case one of the other adsorber-filter cartridges; provision is made for at least one additional adsorber-filter cartridge that is operated for a time in a partial-adsorber state, which cartridge, after the conclusion of its regeneration cycle, is connectable with increasing gas throughput to at least one additional adsorber-filter cartridge running in the adsorber operation.

[ We claim:] [1.] Process for the purification of gases loaded with residues,in which process a gas to be purified is drawn off from regions producing impurities andled via pipes to an arrangement of adsorber-filter cartridgesserving for separation of the impurities from the gas,the cartridges being periodically separated in a cyclical manner from the exhaust-air stream for the carrying out of a regeneration process, andwhose adsorber material is impinged upon by an expelling medium that is suitable for the purification of the adsorber material,wherein, besides a number of adsorber-filter cartridges provided for the continuous carrying out of the purification process and running in an adsorber operation, at least one additional adsorber-filter cartridge is provided that is in the regeneration state in cyclical exchange with in each case one of the other adsorber-filter cartridges,and wherein provision is made for at least one additional adsorber-filter cartridge driven for a time in a partial-adsorber state,which filter, after conclusion of its regeneration cycle, is connectable to a rising gas-throughput volume of at least one additional adsorber-filter cartridge running in the adsorber operation.
