【Q&A Question 068】March 09, 2018: Briefly describe the situations in which hydrogenation units need to be shut down urgently In the event of accidents such as tube rupture in the device, leakage or explosion in the high-pressure hydrogen pipelines, shutdown of hydrogen supply, power outages, or interruption of circulating water, emergency shutdown can be carried out. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.
