Hi
Let's say I have a vessel full of propylene (70% propylene/30% propane) at 25 kg/cm2g and ambient temperature, so that it is in liquid phase. If temperature drops, liquid density will go down. So, will we have a vacuum condition at the vessel? What I think is that, if the vessel cools down to, let's say to 0ºC, liquid propylene will vaporize to some extent and the pressure of the vapor phase will be propylene vapor pressure at 0ºC. Is this correct? Or will the vessel collapse?
Thanks for your help
