Abstract
The addition of a nucleating or coalescing agent (e.g., urea) to liquid ammonia reduces the size and persistence of a deadly, fog-like cloud of ammonia droplets that tend to form when liquid ammonia is accidentally released to the atmosphere. In addition, high purity ammonia is obtained by evaporating ammonia from the ammonia- and nucleating agent-containing composition.
