Summary for the A6G example simulation

This example demonstrates a simplified ammonia synthesis and purification process. Ammonia is produced from a gaseous 3:1 hydrogen-nitrogen feed over an activated iron catalyst at elevated temperature and pressure to achieve modest single-pass conversion (less than 30%). This modest conversion necessitates a large recycle flow rate to return unreacted feed to the converter. Inert gases introduced from upstream natural gas reforming processes can accumulate in the synthesis loop and unfavorably shift reaction equilibrium, necessitating a purge stream.

Use this example simulation to explore the effect of inert concentrations on the synthesis and separation processes for a simplified ammonia synthesis plant.
