Hydrogen purification and oxygen source
Thread Content
This post was last edited by cyooob on 2018-1-29 20:42. Dear everyone: Hello! Our ion-exchange membrane caustic soda plant (with a production capacity of 50,000 tons per year) produces hydrogen, and we have acquired a new downstream customer who requires a very high purity level for the hydrogen – 99.999%. Is there any manufacturer that is capable of purifying hydrogen to such a high standard? Which design company designed it? Could you please provide their contact information? Thank you! :D Also, I would like to ask everyone: how is oxygen generated in hydrogen? Please tell the truth!
The company responsible for hydrogen purification design; we have been working together for 4 years. The main processes include washing, pressure swing adsorption, temperature swing adsorption, deoxygenation, etc. Add me on QQ: 821732635
How is oxygen generated in hydrogen? How is oxygen removed from hydrogen? ? Deoxygenation is actually very simple: hydrogen reacts with oxygen to form water, and then it can be dried directly. This is the simplest process. The oxygen content in the high-purity hydrogen used in our production must be below 1 ppm, which is why we also have a hydrogen purification process.
I think it’s still produced by electrolysis. Although hydrogen is produced industrially by electrolyzing sodium chloride solutions, which yields hydrogen, chlorine, and sodium hydroxide, I think that since water electrolysis produces hydrogen and oxygen as well, it’s impossible to separate them completely in the solution; there must be some oxygen mixed in as well. I’m not exactly sure either, because the hydrogen we use is also supplied by the factory next door; it contains oxygen, and sometimes the concentration of that oxygen is quite high. Perhaps they haven’t managed to control the concentration of the sodium chloride solution they use in electrolysis.
The mechanism by which oxygen is generated in the cathode region is not clear
What’s your contact information?
