What are everyone’s thoughts on the precautions to be taken during the operation of the methanol autothermal conversion unit, as well as potential accident risks?

Hello everyone, I would like to know the precautions that should be taken when starting up the methanol autothermal conversion unit, especially regarding how to make adjustments when adding oxygen to the converter. Thank you!
Oxygenation principle A: Less is better; oxygen can be added in several doses until the desired level is reached. B. Raise the converter temperature until it is within the process specifications. C. Generally, the amount of oxygen added to the process coke oven gas per 1000 m3/h does not exceed 200 m3/h (empirical value)
If the synthetic compressor fails, the venting system must be activated promptly to prevent the system from building up pressure, which could lead to an explosion. This would cause severe damage to the burners as well.
Is there anything else to keep in mind? Thank you so much!
In the pure oxygen catalytic partial oxidation unit, if the compressor stops operating due to its own issues, should the oxygen supply be cut off first, or should the outlet for the conversion gas be opened to allow venting first?
The vent must be turned on; otherwise, the system pressure will rise. If this pressure exceeds that of oxygen, an explosion can occur. It is essential to pay attention to the pressures of both gas and oxygen, ensuring that the oxygen pressure is higher than that of the gas.
It is essential to ensure that the pressure of water vapor is greater than that of oxygen, which in turn is greater than that of gas.
During an emergency stop, pay attention to the sequence in which the media are shut off and verify that they have indeed been shut off. Also, monitor the temperature of the furnace body as well as the temperatures of the upper and lower gas transfer pipes, in order to assess the insulation conditions inside the furnace and the combustion process. Be careful of uneven burning that may occur due to issues with the distribution holes in the oxygen distributor
When the syngas compressor trips, the release of pressure should be done slowly; rapid pressure release will cause the liquid level in the drum to drop quickly, and the temperature of the converter will also drop rapidly. This is very dangerous
The temperature of the converter will also drop rapidly. What dangers could arise? Could you explain in detail? Thank you very much! 9# yb0709
