![]() Read this K-value off the chart (approximately 21.3). The green circle indicates where to read the K-value on the chart. serial number H32438, was read to the nearest 0.5 psi. You cant read the all page of ebook, please click here login for view all. De Priester (15) condensed these charts to 24 by modifying the atmospheric to 1000 psia charts to. Note where the line crosses the methane axis. Use sliders to change the pressure and temperature a green line connects these two points. Then use Equation (6-14) to calculate Kref and from the DePriester chart find.Connect the points with a straight line.On the right-hand vertical axis, locate and mark the point containing the temperature 60☏.On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia. ![]() ![]() Example įor example, to find the K value of methane at 100 psia and 60 ☏. Many DePriester charts have been printed for simple hydrocarbons. "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.
