AMMONIA SEPARATION USING SEMIPERMEABLE MEMBRANES |
摘要 |
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 @X<->, wherein each R is independently H or a straight chain or branched alkyl group and X<-> is an organic or inorganic anion. The said membrane is useful for the selective permeation of ammonia from mixtures of gases containing ammonia, nitrogen and hydrogen. |
