What are the methods for adjusting the temperature of synthetic catalysts?

Reply #22010-03-31

1. Increase or decrease the circulation volume. 2. Adjust the hot and cold bypass lines. 3. Control of methane in the system. 4. Control of ammonia content at the inlet of the synthesis tower. 5. Control of the waste boiler outlet temperature.

The synthesis towers are all equipped with bypasses and coolers (waste heat exchangers), allowing the inlet temperature to be adjusted.

Factors affecting the temperature of the synthesis catalyst: 1. Hydrogen-to-nitrogen ratio 2. Circulation rate 3. Inert gas content (amount of off-gas) 4. Degree of opening of the cooling line in the synthesis tower 5. Ammonia content at the tower inlet 6. Power level of the synthesis furnace during startup, and various other factors
