GASEOUS AMMONIA REMOVAL SYSTEM

摘要

A system and method for passive capture of ammonia in an enclosure containing material that gives off ammonia. The invention allows for the passage of gaseous NH3 through microporous hydrophobic gas-permeable membranes and its capture in a circulated acidic solution with concomitant production of a concentrated non-volatile ammonium salt.

主权项

1. An ammonia gas capture system for reducing the ammonia concentration within an enclosure, comprising:
A membrane assembly having a permeable membrane wherein said permeable membrane allows for diffusion of ammonia gas concentrated outside said membrane's outer surface through the membrane wherein said ammonia gas contacts an acid supply, a reservoir containing an acid supply wherein in said reservoir pumps said acid supply through said membrane assembly; and a delivery system for delivering acid from the reservoir to said membrane assembly in order to chemically change the ammonia gas to ammonium salts and for carrying the salts to and said reservoir.
