If a 40 mole ethanol, 60 mole water mixture at 60°. Read this K-value off the chart (approximately 21.3). D20 Use the DePriester chart to generate the temperature-composition diagram for isobutane. 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 ☏. Ser 7, 49, 1 (1953), which cover 12 hydrocarbons (methane, ethylene, ethane, propylene, propane, isobutane, isobutylene, /i-butane, isopentane, /1-pentane, /i-hexane, and /i-heptane). Many DePriester charts have been printed for simple hydrocarbons. The easiest to use are the DePriester charts Chem. '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. ( December 2018)ĭePriester Charts provide an efficient method to find the vapor-liquid equilibrium ratios for different substances at different conditions of pressure and temperature. and guess temperature to determine the K-values fromthe DePriester chart.
