![]() In other words, the higher is the relative volatility of a liquid mixture, the easier it is to separate the mixture components by distillation. ![]() This interactive simulation demonstrates howto use the DePriester chart for hydrocarbons.ĭepriester Chart And K Values Trial Distillation Processes And so the idea is we can quickly use a nomographto calculate the K values, and the K value for a given component is the mole fractionof that component in the vapor phase divided by the mole fraction of that component inthe liquid phase, and so when we're looking at mixtures we can get K values for. This article is about Relative volatility. For other uses of the term Volatility, please see Volatility (disambiguation).DePriester charts are used to tabulate K-value data for hydrocarbon systems.
