May I ask about the methanol content in the steam produced by purging with 0.3 MPa steam at around 0.1 MPa and 120 degrees Celsius?
Thread Content
Is there any way to separate methanol vapor from water vapor in the vapor phase, using steam at 0.3 MPa to purge the methanol – with a pressure of 0.1 MPa and a temperature of around 120 degrees Celsius, where the methanol vapor content is 30–50% and the rest is water vapor?
Is it possible to separate nitrogen and oxygen in the gas phase?
The adsorbent won’t work; both of them will absorb it. It’s possible with membranes, depending on whether there are any existing cases
No, methanol will also be absorbed, and it needs to be blown out as well
What about a mixed vapor of water and water-insoluble solvents? Is there a way to separate them?
For water and water-insoluble solvents, why is gas-phase separation needed? Can’t liquid layer separation be used instead?
Add a catalyst to convert methanol into hydrogen and carbon dioxide
Liquid-phase separation requires condensation, and subsequent heating is needed for vaporization – the cost is too high; therefore, it is desired to separate water from the solvent directly in steam
Methanol cannot be changed; what is needed later is still methanol
Is it possible to directly separate non-water-soluble substances from water in the vapor phase?
