Webfollowed by thermolysis of urea into ammonia and isocyanic acid, (NH2)2CO(l) → NH3(g) + HNCO(g) (2) and by hydrolysis of the isocyanic acid: HNCO(g) + H2O(g) → NH3(g) + CO2(g) (3) As water evaporates from the droplets and urea concentration increases, the vapor pressure of water decreases. WebJun 15, 2024 · For example, pure ammonia at -4°F (-20°C) has a saturation pressure of 12.9 psig (0.90 barg). An ammonia-water solution of 10% water and 90% ammonia by weight, at the same -4°F (-20°C) has a saturation …
