Request: T-P Relationship of LPG

[Paks]

Can someone create me a T-P relationship for 30% Butane & 70% Propane Mixture using Hysys v7.1, the same with 35~50%Butane and 65~50% Propane. This is really urgent, please help me. Since i dont have client for this apps. Just send me the tabulated data, or a graph with this e-mail

pakskyo@yahoo.com

Thank you in advance to those who can help me.

Here you go. Done with UniSim using Peng-Robinson EoS rather than HYSYS, but results should be the same.

@Gtaa

can i ask for a data if there is ? i want to know the pressure at certain temperature, like 30degC, the bar would be___.

And hmm how should i say this, can you email me the steps in creating the graph using that software you just created. ((IM USING THIS IN OUR THESIS STUDY for undergraduate ME.)

Thank you

It will have to wait until Tuesday when I get back to the office. Can't you just read it off the graph? Draw a line from 30degC and read off the pressure at either the bubble point or dew point lines?

UniSim and HYSYS are essentially the same thing. You use the 'envelope' utility and it draws it for you. However, to create the bubble point curve manually you set the vapor fraction to 0 and change the temperature in increments. The software will calculate the corresponding pressure. Just plot these. You create the dew point line by setting the vapor fraction to 1 and doing the same thing.
