Read this K-value off the chart (approximately 21.3).

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☏.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. View Notes - HW1 from CHEN 415 at American University of Beirut. 'K' values, representing the tendency of a given chemical species to partition itself preferentially between liquid and vapor phases, are plotted in between. The values of K have been correlated empirically or theoretically in. Although, alternative design 1 and 2 have more number of equipment compared to the. Another reason for the reduced energy consumption is the improved design of the process which helped to reduce the exergy losses. These nomograms have two vertical coordinates, one for pressure, and another for temperature. DePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and. depriester chart in a sentence - Use depriester chart in a sentence and its meaning 1. The use of liquid CO 2 cold energy for the power generation using Rankine cycle reduced the net power consumption of the process. 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.
