Reasons for high pressure in the synthesis loop
Thread Content
Dear experts, what are the reasons for high pressure in the synthesis circuit section? How to solve it?
1. The hydrogen-to-nitrogen ratio is inappropriate, resulting in poor synthesis reaction. Measure: Adjust the hydrogen-to-nitrogen ratio properly. 2. The cooling effect of the water cooler or ammonia cooler is poor, resulting in a high ammonia content in the circulating air. Measure: Reduce the gas temperature at the outlet of the water cooler or ammonia cooler. 3. Catalyst activity degradation leads to poor synthesis reaction performance. Measure: Continue production or replace the catalyst. 4. Catalyst pulverization or sintering adhesion results in high resistance in the catalyst bed. Measure: Continue production or replace the catalyst. 5. The system load is too high. Measure: Adjust the system load.
