1. A process for separating methane or nitrogen from a fluid mixture comprising methane and nitrogen, the process comprising: (A) flowing the fluid mixture into a microchannel separator, the microchannel separator comprising a plurality of process microchannels containing a sorption medium, the sorption medium having a preferential affinity for sorbing methane over nitrogen, the fluid mixture being maintained in the microchannel separator until at least part of the methane is sorbed by the sorption medium, and removing non-sorbed parts of the fluid mixture from the microchannel separator; (B) desorbing the methane from the sorption medium and removing the desorbed methane from the microchannel separator; and wherein tail gas is produced during step (A).
