Hi

I'm trying to find an online resource or a method of how to calculate the temperature/pressure a liquid will become a gas. For instance, If propane is at -40F at 19bar flowing through a pipeline how much will the pressure have to drop along the pipe before it reverts back to a gas?

I've had a good root round on the web, and through my books but I can't find much 'specific' info on this topic. Is there an online resource or method I can employ to look at phase change for a host of different liquids or can this only be achieved through experimental method?

Thanks for the links gvdlans , I had already come across those though and the limits are below what I was looking for. However, I have managed to find a pdf for some 'PHASE BEHAVIOR OF NATURAL GAS SYSTEMS' I've uploaded it in case anyone else is interested

Many thanks

James
