Ammonia is produced by reacting nitrogen from the air with hydrogen. Hydrogen is usually obtained from steam reformation of methane, and nitrogen is obtained from deoxygenated air. The chemical reaction is shown below:

Our goal is to produce a simulation for the production of ammonia using DWSIM. A diagram and the data needed to simulate this process is given below.
