Follow-up actions after hydrogen emergency pressure relief activation

1. What are the subsequent steps after initiating the hydrogen emergency pressure relief? 2. What areas need to be checked during outdoor operations? 3 What are the safety precautions?
If starting at 0.7 bar, following the relevant procedures will ensure no problems occur. The steps are as follows: 1. Verify on-site whether the emergency pressure relief valve has activated. 2. Check whether the associated interlocks have been activated, such as those related to the feed pump, the new hydrogen generator, and the reaction heating furnace; it is also necessary to confirm that the corresponding electric valves are closed, and that the manual valves of the reaction furnace’s burners are closed to maintain a steady flame. 3. Stop feeding water on-site. 4. Halt feed to the tank area. 5. The reaction requires hot hydrogen to carry the oil. 6. Inspect all the tight sealing points of the heat exchangers. 7. In winter, the feed pump needs to be flushed with oil
