What software can be used to find out the boiling points of different substances at various pressures? For example, what is the boiling point of C4h10 at 1.0 MPA?
I am also looking for such software; let’s look forward to it together.
This problem is a piece of cake for ASPEN. Method 1: Select the components and thermodynamic methods, create a stream, assign arbitrary values; set the stream pressure to the value you want to calculate, and the temperature to the bubble point (or a gas phase fraction of 0). After running it, simply check the results ； Method 2: Select the component and use thermodynamic methods; go to Analysis----Property-----Pure in the tool to directly obtain the relationship between the boiling point and pressure of the component.
All process simulation software – Aspen Plus, Aspen HYSYS, Invensys ProII, BR&E Promax, VMG SIM, ChemCAD – can all perform what you mentioned; it’s all available in eDonkey
Aspen can be used; here is a lecture note for your reference: http://bbs.hcbbs.com/thread-436491-1-1.html (Property estimation)
Use your second method, but since only the vapor pressure changes with temperature, I want to fix the pressure as the horizontal axis in order to create a curve showing how the boiling point changes with pressure. How should I do that?
Just paste the data into Excel and redraw it with pressure on the X-axis, and that’s it. A crude trick.
I can’t view it after downloading; it’s a backup file. Is there an original version?
