【Daily Question】Chemical Engineering Principles 310: Hydrogen Production Equipment (January 30)
Thread Content
This post was last edited by “Back to Cambridge” on February 5, 2016, at 17:06. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer: Why is it necessary to fill the system with nitrogen before starting up hydrogen production equipment? Answer: The system needs to be filled with nitrogen when hydrogen production equipment is shut down for a period of time or is restarted after maintenance. The purpose of nitrogen filling is mainly to displace other gases in the system other than nitrogen, and then to remove the nitrogen through the vent valve. Since nitrogen and hydrogen hardly undergo chemical reactions under normal conditions, nitrogen purging is typically used before starting up. Additionally, filling the system with nitrogen can also be used to conduct a gas-tightness test of the system in order to locate leak sources.
Prevent the formation of an explosive mixture caused by air in the system memory and the hydrogen produced
Answer: The system needs to be filled with nitrogen when hydrogen production equipment is shut down for a period of time or is restarted after maintenance. The purpose of nitrogen filling is mainly to displace other gases in the system apart from nitrogen, and then to remove the nitrogen through the vent valve. Since nitrogen and hydrogen hardly undergo chemical reactions under normal conditions, nitrogen purging is typically used before starting up. Additionally, filling the system with nitrogen can also be used to conduct a gas-tightness test of the system in order to locate leak sources.

Guess – nitrogen filling is generally used to displace air and maintain a certain pressure inside the container
