The amount of hydrogen mixed in during pre-hydrogenation suddenly decreased
Thread Content
The amount of hydrogen mixed in during pre-hydrogenation suddenly decreases or even reaches zero, causing temperature deviations at the furnace chamber and the outlets of the four furnaces, which in turn leads to an increase in the temperature of two of these outlets. The furnace suddenly exploded. What aspects cause it?
The circulating hydrogen flow rate is zero; there may be an error in the flow rate display； But there were reactions in the furnaces later on; it was a problem with the pre-hydrogenation cycle hydrogen compressor ；
Failure of the circulating hydrogen compressor, failure of the control valve, or incorrect valve operation due to misoperation.
The compressor is fine, and there is no fault with the control valve either.
Could it be that the excessive pressure in the pre-hydrogenation reactor caused the hydrogen mixing control valve to close partially or completely, resulting in a disruption of hydrogen mixing and an increase in reaction temperature, which in turn triggered the series of subsequent accidents? Do you have any records from that time? Please check them and share some data or specific details with us; otherwise, we can only rely on guesses!
