Analysis of ammonia separation from purge gases in microporous hollow fiber membrane contactors.
TL;DR: A mathematical model developed to analyze the separation of ammonia from the purge gas of ammonia plants using microporous hollow fiber membrane contactors revealed that the membrane wetting did not have significant effect on the absorption of ammonia because of very high solubility of ammonia in water.
