Starting from the bottoms, point ( x xB 0.02, y x B), a bubble point calculation with x 0. Example įor example, to find the K value of methane at 100 psia and 60 ☏. 4-38 Table 4.4-6 lists the Matlab codes for the number of equilibrium stages. 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. Pressure and vapor composition for a liquid mixture of ethanol (1) n hexane (2) at 331 K, X10.412. 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.
