Production of industrial synthetic ammonia

2009-03-25View Original

Thread Content

High-pressure method: The operating pressure is 70–100 MPa. The advantage is that the ammonia synthesis reaction has a fast rate and high yield ; Ammonia in the gas after the reaction can be easily separated ; Simple process, relatively compact equipment, etc ; A disadvantage is that the ammonia synthesis reaction releases a large amount of heat, resulting in high temperatures in the catalyst bed. If this heat is not properly controlled and not removed in a timely manner, it can cause the catalyst to overheat, leading to its damage or loss of activity; as a result, the service life of the catalyst is relatively short ; Operating under high pressure requires high standards for equipment manufacturing and materials, as well as significant investment costs. It is rarely used in industry at present ;
