What should be done in the case of a sudden power outage during the catalyst heating and reduction process?
Hydrogen supply was stopped on site, and medium-pressure nitrogen was urgently introduced for displacement; after multiple displacements, the system remained at a slight positive pressure.
Stop heating up； After displacement cooling ； Just keep raising the temperature for reduction
It depends on the stage: it’s not necessary when physical water is produced, but when chemical water is produced, the reducing agents must be removed and the system needs to be purged with nitrogen
Nitrogen displacement, venting after expanding the tower, forced ventilation, airflow movement, heat removal, preventing the synthesis tower from being damaged, catalyst sintering, secondary displacement, slight positive pressure in the system

1. Stop reducing hydrogen gas. 2. Stop the heat source. 3. Release pressure and replace with nitrogen. 4. Restore under suitable conditions.
