Abstract
The present invention is a process for separating ammonia from mixtures of other gases or from aqueous streams. The ammonia-containing mixture is contacted with a membrane containing, as the active component, a salt having the structural formula: NR.sub.4.sup.+ X.sup.-, wherein each R is independently H or a straight chain or branched alkyl group and X.sup.- is an organic or inorganic anion. The membrane is useful for the selective permeation of ammonia from mixtures of gases containing ammonia, nitrogen and hydrogen.
