How to deal with overheating during the gas introduction process in a CO transformation? Can it increase the air flow volume?
Increase the water-to-vapor ratio to reduce system pressure
Before introducing gas, ensure that the bed temperature is high; in such cases, a large volume of gas can be introduced. If overheating occurs during the gas introduction process, nitrogen or steam can be added, or the pressure can be reduced
Steam can be added or the pressure can be reduced to increase the water-vapor ratio and lower the system pressure
It depends on to what extent the temperature has risen; if it’s approaching the device’s designed temperature, it’s better to reduce the pressure.
The air velocity is low, so the heat of reaction cannot be carried away, resulting in overheating; increasing the air velocity and introducing more air into the system helps
Increase the air velocity and introduce nitrogen as a gas distribution agent.
