Abstract
The present invention provides an apparatus for desubliming a target compound from a first gas mixture containing the target compound, comprising a desublimation means comprising a surface onto which desublimation of the target compound can occur; a cooling means that cools the desublimation means; an inlet through which the first gas mixture can enter the apparatus such that it comes into contact with the surface of the desublimation means in a contact region; a target compound recovery region; an outlet through which the target compound can leave the target compound recovery region; a first path for the desublimation means that extends from the cooling means to the contact region before returning to the cooling means without passing through the target compound recovery region; and a second path extending from the first path to the target compound recovery region and then back to the first path, wherein the desublimation means is movable along said paths.
