What gas components can dissolve in liquid ammonia?
Thread Content
Dear experts, the gas ammonia composition at the outlet of the ammonia cooler is NH3 85.7%, H2 1.4%, Ar 3.3%, N2 6.1%, and CH4 3.5%. Will hydrogen, methane, and argon dissolve in liquid ammonia? Is there a slight leak in the ammonia cooler? Additionally, the pressure at the gaseous ammonia outlet is 0.03 MPa higher than normal during production.
Liquid ammonia can dissolve hydrogen, nitrogen, methane, and argon. As for the composition of gaseous ammonia mentioned above, it could be due to a leak in the ammonia cooler, or it might not be; the key is to analyze the source of the liquid ammonia and the processes it has gone through before being used in the ammonia cooler. Only through such a comprehensive analysis can it be determined how much gas is dissolved in the liquid ammonia, and then it becomes possible to determine whether there is an internal leak in the ammonia cooler. The gases dissolved in liquid ammonia can be determined using various temperature and pressure parameters (Nitrogen Fertilizer Process Design Manual, Physical and Chemical Data Volume). The parameters for synthesis should be selected reasonably, and cannot be determined solely based on the parameters for ammonia cooling. That is, analyze specific problems specifically.
