ajs1972,
Will this give a conservative way to size the relief valve? Ir your mixture has a small component of something with a lower boiling point and latent heat of vaporization should the valve be sized based on this component since it will boil off first?
I meant to clarify that this is a mixture of hydrocarbons. I have come across some discussions on whether the latent heat should be used for the lighter components rather than for the entire mixture. What is the correct method for PSV sizing?
I am looking at a fire relief case for a vessel. In this case the heat added by the fire will have to increase the liquid temperature to its boiling point and then at that temperature enough heat would need to be added to vaporize the liquid and increase the pressure to the relieving...
