How to plot pxy diagram. 5. The video is used with permission from LearnChemE, a project at the University of Colorado funded by the National Science Foundation and the Shell Corporation. 2. Calculate activity coefficients γ 1 and γ 2 based on activity coefficient model selected from Wilson, NRTL and UNIQUAC. 01 in spreadsheet. Open HYSYS V8. They y-coordinates show the pressure of the mixture and the x-coordinates show the mole fraction of benzene in liquid and/or vapour phases. "Model Palette" click 4. A graph that shows the relationship between liquid phase composition x, gas phase composition y, and pressure P for two components at a constant temperature is called a Pxy diagram. Click and drag the black dot on either diagram and the bar chart shows the amounts of liquid (blue) and vapor (green) present; the system Binary Phase Diagrams for Ideal Mixtures Summary This notebook shows how to use Raoult's Law and Antoine's equations to calculate Pxy, Txy, and xy diagrams for binary mixtures.
