Looking for literature/advice: liquifying CO2 with 20% H2 under 50 bar

[gromzek]

Hey there!

Actually, I'm working on a process where I need to liquify the CO2 of a gas mixture of 80% CO2 and 20% H2 at 50 bar. I need some information about how the H2 influences the condensation of the CO2 during the process (influence on CO2's properties like boiling temperature and general process behavior). The H2 is in supercritical state due to the high pressure (pc = 13 bar, Tc = 33 K).

Can someone recommend some books, papers or articles which could help or has some experience with this topic?

Thanks and kind regards!

gromzek,

If you are lucky Arthur Montemayor will reply. He has experience with CO2. If he doesn't reply here in a few days, try him over at ChEResources website, he's either the admin or moderator there.

Good Luck,
Latexman

CO2 Scrubbers are perhaps the most effective process to isolate the H2, but for recoverable CO2 activated carbon processes will work, leading to a higher concentration of H2.

Try

20% though is very high.

Adding h2 seems to push the phase diagram above the pure co2 lone.
