Atmospheric Dispersion of Ammonia: An Ammonia Fog Model.

摘要

Ammonia (NH sub 3 ), a by-product of many chemical processes, is widely used as a fertilizer and as a raw material for many chemical syntheses. The purpose of this paper is to discuss the atmospheric dispersion of ammonia resulting from a high pressure release. The resulting nature of the two-phase cloud of ammonia vapor and droplets has a significant effect on its dispersion characteristics. Our calculations of a 40 ton release show that even under moderately high wind conditions, the resulting ammonia cloud remains negatively buoyant for considerable distances downwind. 10 references, 15 figures.
