How can the synthesis rate of synthetic ammonia be increased? ? ?
1. Adjust the ingredients properly. 2. Maintain catalyst activity. 3. Adjust the circulation volume properly. 4. Operate at a catalyst activity temperature of over 50 degrees.
Unless the above measures are taken, based on the principles of reaction kinetics, 1. increasing the reaction pressure within the process range； 2. Remove the reaction heat as soon as possible ； 3. Provide the ammonia separation efficiency behind the tower, etc.
1. Develop a set of appropriate process parameters based on the actual production conditions. 2. Strictly control these process parameters
The ammonia synthesis process is now mature; its conversion rate is not very high to begin with. I’ve heard that even a 1% increase can make a significant difference. In fact, the main considerations are thermodynamic and kinetic conditions, on which the optimal process conditions for ammonia synthesis are determined. The selection of pressure is actually the most difficult aspect; increasing the pressure can boost production capacity, and at the same time, the ammonia separation process can be simplified. However, high pressure imposes higher requirements on the materials, and the catalyst’s lifespan is also shortened.
1. Adjust the gas composition properly； 2. Increase the pressure in the synthesis system ； 3. Maintain an appropriately controlled catalyst layer temperature ； 4. Minimize the temperature of the gas exiting the ammonia cooler as much as possible ；
