So this is my first VLE Generator using the Dalton's Law and Raoult's Law I managed to whip up in Excel. It simultaneously calculates the VLE using the DIPPR equations for vapor pressures and heat capacities. Obviously, this is still in BETA stage; so please do not expect anything grand. The instructions for the use of this thing is really, really simple: you simply select two components and press F9. Hue. :rofl:

Normally the calculations converge in five iterations. The calculated VLE and enthalpies can be found, copied and pasted somewhere else from the "DATA" tab. Constants here comes from the Perry's Handbook, 8th edition.

Special thanks toChestermillerfor helping me whip this thing up, in particular the enthalpy curves, and for everything I do not understand in the chemical engineering domain for that matter. My mind was literally in chaos when I wasn't sure with the enthalpy balances.

And yes, if you may have noticed, there's an option there which says "THERMODYNAMIC MODEL". Don't bother changing them yet, they aren't ready. And for the curious mind, I used the Newton Iteration and the Simpson's cubic integration method for the VLE and the enthalpies, respectively.

DISCLAIMER: I don't take any blame if a chemical plant blows up because of this program, or any untoward incident for that matter. :rofl: This is up here also because it needs more suggestions and other stuffs.
