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.Your value gets instantly converted to all other units on the page. 2: Enter the value you want to convert (kilopascal). You can also go to the universal conversion page. To switch the unit simply find the one you want on the page and click it. On the right-hand vertical axis, locate and mark the point containing the temperature 60☏. This is a conversion chart for kilopascal (Metric).Name two factors that influence the VLE behavior of a component or set of components. K-value Using DePriester Chart For light hydrocarbon mixture (commonly found in. In thermodynamics, you learned about negative and positive deviations from ideality.

On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia. At 100C and a pressure of 200.0 kPa, what is the K value of n-hexane b. Drum pressure 250 kPa, drum temperature 10☌.

Example įor example, to find the K value of methane at 100 psia and 60 ☏. In(psat PPCH,0, kPa) 13.8254 - 2181.79 t + 248.870 psat 20 1788.0 1075.8 Selected Antoine Coefficients Adapted from Intreluctory Chemical Engineering Thermodynamics, J. If an equation for K is given as function of temperature and pressure, this temperature can be obtained by setting K 1. Please determine Kic, and 50 C and 150 kPa via (a) the De Priester Charts and (b) Raoult's Law w/ Antoine's Eq. Assume a temperature T ( ) Tbi Boiling point of pure component i at pressure P.

"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.
