The last edit to this post was made by Zaihui Kangqiao on 2016-3-28 at 13:37. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series such as \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" will also be introduced. We hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" activity can be viewed directly, and the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What should be done when hot work is required in a hydrogen production system? Answer: When performing hot work near hydrogen production stations and hydrogen systems, it is necessary to follow the relevant procedures for hot work permits. Before starting such work, various measures must be taken to ensure that the hydrogen concentration both inside the system and in the area where hot work is being carried out does not exceed 1%.
What should be done when hot work is required in a hydrogen production system? When performing hot work on the hydrogen production system, it is necessary to follow the relevant hot work procedures. Before starting such work, various measures must be taken to ensure that the hydrogen concentration both inside the system and in the area where hot work is carried out does not exceed 0.4%
Follow the regulations regarding hot work permits; before carrying out such work, take all necessary measures to ensure that the hydrogen concentration both within the system and in the area where work is being done does not exceed 1%
Pressure relief through venting, nitrogen purging, isolation with blind flanges, purging, and successful laboratory analysis.
