Here is an example of how to use a DePriester chart for propane at 70 psia and 20 °F: 1. Use the sliders to set the pressure and temperature. The green line connects these two points. The K-value is where the green line intersects the curve for propane (K = 0.8). 800 900 1000 1500 2000 2500 3500 4000.00'.00.00'.00' o 70 60 50 40 30 20.00 X 101.3 Ito 150 200 250 300 400 500 600.90 zz zz zz z x z z.

This Demonstration applies a DePriester chart, a set of nomograms to find the vapor-liquid equilibrium ratio (the gas phase mole fraction divided by the liquid phase mole fraction, known as the -value) for a series of hydrocarbons. Select one of three hydrocarbons: methane, propane or -decane. Use sliders to change the pressure and temperature; a green line connects these two points. The green circle indicates where to read the -value on the chart, which is also displayed above the chart. The -values for other hydrocarbons can also be read from the chart.
