【Q&A Question 103】April 13, 2017: What are the steps for an emergency shutdown of the new hydrogen compressor? The reference answer will be shown after responding; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 1. Immediately cut off the power supply (press the stop button); if possible, reduce the load to 0% first ； 2. Close the main inlet and outlet valves, and open the pressure relief valve to release pressure ； 3. For other cases, follow the normal shutdown procedures. Scoring criteria: Incorrect answers result in 2 Wealth points; *incomplete* answers earn 3–8 points. Correct answers with a detailed explanation grant 10 Wealth points, while correct answers with insufficient supplementary *answers* yield 15–20 Wealth points.
