A sublimation apparatus comprising an inner vessel placed within an outer vessel leaving an interspace between them. Inlets and outlets for a gas to be treated are connected to the inner vessel. Plurality of parallel-connected heat exchange channels are provided around the inner vessel, which heat exchange channels are connected to a bottom header and to a top header. A heat exchanger is placed in the top header. The apparatus further has a first reservoir for a first heat exchange medium. A closable connecting duct connects the bottom header and the first reservoir, and another connecting duct connects a vapor space of the first reservoir and the top header. A second reservoir for a second heat exchange medium different from the first heat exchange medium is connected by a closable connecting duct to the interspace between the inner and outer vessels. A closable connecting duct connects a vapor space of the second reservoir with the top portion of the interspace. The second reservoir is provided with a heating element.
