ABSTRACT:
Separate recovery of high and low molecular weight gases from a gaseous starting mixture, e.g. a mixture resulting from thermal water splitting. A set of three chambers is used which are arranged in series and separated by membranes permeable preferentially to the low molecular gas. Gases permeate from the first to the second chamber and from there to the third chamber. A gaseous mixture enriched with the high molecular weight gas is withdrawn from the first chamber and a gaseous mixture enriched with the low molecular weight gas is withdrawn from the third chamber. Undesired gaseous components are rendered non-gaseous and the remaining low and high molecular weight gases are withdrawn separately.
