Abstract

A separating nozzle element composed of a separating body and end plates enclosing the body, for separating components of gaseous or vaporous mixtures, the separating body being provided with separating structures which delimit separating chambers and gas conduits and the end plates being provided with channels for supplying gas to, and removing gas streams from, the separating chambers and conduits, in which the separating body is produced in successive contiguous layers by carrying out the following sequence of steps a plurality of times until a given separating body thickness is achieved: providing a mold layer; irradiating selected portions of the layer with radiation in a spatial pattern corresponding to the separating structures to render only selected regions of the layer which correspond to the separating structures removable in a predetermined manner; removing the selected regions; and filling the spaces thus created in the layer with a material which is compatible with the gaseous or vaporous mixture whose components are to be separated, in order to form a laminar portion of the separating structures, and after the desired thickness is achieved, removing the remaining mat…
