Description
At atmospheric pressure, ammonia is a colorless gas with a characteristic pungent odor, which is extremely irritating to the eyes and upper respiratory tract. It is approximately half as dense as air and thus rises readily. With pressurization, 13 cubic feet of ammonia vapor can be condensed into 1 cubic foot.
Ammonia is a common chemical of production, holding a third place in world production (Makarovsky et al., 2008). The large-scale use of ammonia is facilitated by large-scale storage
