Recovery of carbon dioxide containing propylene oxide.
Thread Content
Carbon dioxide gas contains propylene oxide, with a PO content of 0.5% – 1% V/V. Is it possible to purify it through methods such as washing before freezing the carbon dioxide into a liquid state for use? I hope everyone can give some practical suggestions – are there any feasible solutions?
It should be possible. Look for one with high solubility in propylene oxide, low solubility in carbon dioxide, and no chemical reaction with carbon dioxide; to make a specific choice, check the property tables of these two substances
