The tables and figures below show how the boiling point changes with increasing carbon number up to C 33 for different kinds of hydrocarbons, alcohols and carboxylic acids.Read this K-value off the chart (approximately 21.3). Note where the line crosses the methane axis.Preferred analytical correlations are less empirical in nature and most often are theoretically based on one of two exact thermodynamic formulations, as derived in Sec.

We want to calculate the product compositions (L and V ) from the flash drum. applied to vapor/liquid equilibrium, the goal is to find by calculation the.Exampleįor 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.
