Note where the line crosses the methane axis.Connect the points with a straight line.On the right-hand vertical axis, locate and mark the point containing the temperature 60☏.

kilopascals (kPa) pounds per square inch (psi) 1 kPa.

On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia. For quick reference purposes, below is a conversion table that you can use to convert from kPa to psi.

Example įor example, to find the K value of methane at 100 psia and 60 ☏. DePriester Charts K-Values of light hydrocarbon systems, generalized correlations.

Many DePriester charts have been printed for simple hydrocarbons. At 100C and a pressure of 200.0 kPa, what is the K value of n-hexane b. for restrictions of: 3 < 0.01, yj - 0, and P < 200 kPa. "K" values, representing the tendency of a given chemical species to partition itself preferentially between liquid and vapor phases, are plotted in between. These nomograms have two vertical coordinates, one for pressure, and another for temperature. DePriester in an article in Chemical Engineering Progress in 1953. DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature.
