Gaseous ammonia removal method |
| 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. |

1. A method for producing ammonium salt from an enclosure, comprising:
capturing ammonia gas within the confines of a membrane assembly having a gas-permeable membrane, said gas generated substantially from material containing ammonium, contacting said ammonia gas with an acid solution in said membrane assembly wherein said acid is in fluid communication with said gas to produce ammonium salts; and transporting the salts for collection to a reservoir in fluid communication with said membrane assembly. |
