Why is pressure relief and replacement necessary after the conversion system is shut down? Answer: The ratio of process gas to water vapor in the shift converter is relatively high. If pressure is not relieved and the system is not replaced after shutdown, as the temperature of the catalyst bed decreases, water vapor will condense within the shift converter, which is detrimental to the catalyst.
The ratio of process gas to water vapor in the shift converter is relatively high; if pressure is not relieved and the system is not purged after shutdown, as the temperature of the catalyst bed drops, water vapor will condense within the shift converter, which is detrimental to the catalyst.
The ratio of process gas to water vapor in the shift converter is relatively high; if pressure is not relieved and the system is not purged after shutdown, as the temperature of the catalyst bed decreases, water vapor will condense within the shift converter, which is detrimental to the catalyst. Therefore, after the conversion system is shut down, pressure must be relieved and replaced.
Answer: The ratio of process gas to water vapor in the shift converter is relatively high. If pressure is not relieved and the system is not purged after shutdown, as the temperature of the catalyst bed decreases, water vapor will condense within the shift converter, which is detrimental to the catalyst. Therefore, after the conversion system is shut down, pressure must be released for replacement.
The ratio of process gas to water vapor in the shift converter is relatively high; if pressure is not relieved and the system is not purged after shutdown, as the temperature of the catalyst bed drops, water vapor will condense within the shift converter, which is detrimental to the catalyst.
As the bed temperature decreases, water vapor condenses, which is not favorable for the catalyst
The ratio of process gas to water vapor in the shift converter is relatively high; if pressure is not relieved and the system is not purged after shutdown, as the temperature of the catalyst bed decreases, water vapor will condense within the shift converter, which is detrimental to the catalyst.
The process gas in the shift converter has a high water-to-gas ratio; if it is not replaced after shutdown, as the temperature of the catalyst bed drops, water vapor will condense within the shift converter, which is detrimental to the catalyst. Therefore, after the conversion system is shut down, it must be purged with nitrogen and kept under pressure to prevent air from entering
The moisture level is relatively high; if not replaced, the condensate formed after cooling will damage the catalyst
The process gas in the shift converter contains a high water vapor ratio; if it is not replaced after shutdown, as the temperature of the catalyst bed drops, water vapor will condense within the shift converter, which is detrimental to the catalyst. Therefore, after the conversion system is shut down, it must be purged with nitrogen and kept under pressure to prevent air from entering.
