Reasons for the increase in pressure in the synthesis tower system
Thread Content
As the title suggests, what are the reasons for the increase in pressure in the synthesis tower system? Everyone is welcome to participate actively in the discussion
1. High gaseous ammonia pressure and high ammonia cooling temperature result in a high concentration of ammonia at the inlet, which inhibits the synthesis reaction. 2. Imbalance in the hydrogen-to-nitrogen ratio. 3. Excess levels of CO and CO2 cause poisoning of the synthesis catalyst. 4. The methane content in the air is high. 5. Large air supply capacity. All of the above reasons can lead to high pressure in the synthesis system
Reply to 1# slei0562: 1. The load on the synthesis system increases. 2. The synthesis tower has poor reaction performance, even across different temperatures. 3. The gas composition changes, and the average molecular weight increases. 4. The amount of gas flowing in the reverse path decreases. 5. The ammonia content in the gas entering the tower increases. 6. The exhaust gas flow rate is low, and the methane content in the gas entering the tower increases. 7. An imbalance in the hydrogen-to-nitrogen ratio results in poor synthesis reactions. 8. Prolonged use of contact media leads to toxicity and inactivation. 9. Ammonia in the circulation belt.
