DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature. The original chart was put forth by C.L. DePriester in an article in Chemical Engineering Progress in 1953. These nomograms have two vertical coordinates, one for pressure, and another for temperature. 'K' values, representing the tendency of a given chemical species to partition itself preferentially between liquid and vapor phases, are plotted in between.[1][2][3][4] Many DePriester charts have been printed for simple hydrocarbons.[5][6]
Example[edit]
For example, to find the K value of methane at 100 psia and 60 °F.
- On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia.
- On the right-hand vertical axis, locate and mark the point containing the temperature 60°F.
- Connect the points with a straight line.
- Note where the line crosses the methane axis. Read this K-value off the chart (approximately 21.3).

This page is designed to allow users to select a pure component or a mixture of components and determine the vapor-liquid split (if two-phase), the liquid and vapor densities, enthalpies, heat capacities, and compositions at an input temperature and pressure. It then performs an adiabatic flash calculation from the input pressure to one atmosphere and displays the final properties. This page is currently using the Peng-Robinson equation of state to predict the properties of these mixtures. To try it out, create an input mixture using the form below and hit the submit button to start the calculations.
