Problems with natural gas-based hydrogen production facilities
Thread Content
Gentlemen, in the hydrogen production start-up and shutdown plans as well as the operating procedures, I found that during operation more attention should be paid to the methanation reaction in the hydrogenation reactor, whereas the medium-pressure shift reactor is mentioned very little. But I think the medium-pressure reactor is more likely to undergo methanation reactions, right? Also, what should be done if methanation occurs in the medium-pressure reactor during the shutdown process?
That document describes a large number of methanation reactions among the intermediate reaction types
I didn’t understand what you meant First, you need to understand the functions of desulfurizers, converters, shift converters, and PSA
