Help- how to calculate the rate of vaporation capacity of lpg ?

Hi...

I think you able to use hysys:
1. Use your LPG component
2. Set pressure 5 barg
3. Set flow 100 lb/hr
4. Use case study with pressure 5 bar g and range temperature you want (i.e 20-100 deg C)
5. You will get vapor fraction of LPG at that pressure.
6. If you need any other opinions pls let me know.

If other member have other answer will be good for all of us

I think hysys only show the result not completly usefull in this case.
And in this case I want to caculate the capacity of vaporization of LPG in 100lbs cylinder, not for the flow 100lb/hr.
First we have to find the heat exchange from the environment to the liquid phase through the cylinder. Then according to the three phase and latent heat of LPG we can find the answer. I just seek a liitle bit
If you have any opinion, we can discuss more about this.
Thanks so much..
