This problem has been solved. It was found that smaller errors resulted when.Recognize and detect the effects of electrostatic charges on your balanceI provided the DePriester chart for more information of the K-value. To see how to use the DePriester ChartsData were taken from DePriesters nomographs.2 Values of the regression coefficients are shown in Table I. These nomograms have a co-ordinate each of pressure and temperature and have 'K' values ingeniously plotted in between. DePriester Charts present an efficient method in finding the equilibirum ratios for different substances at different conditions of pressure and temperature.

As the value of О± increases above 1, separation by distillation becomes progressively easier.A liquid mixture containing two components is called a binary mixture. When the volatilities of both key components are equal, О± = 1 and separation of the two by distillation would be impossible under the given conditions. That means that О± в‰Ґ 1 since the larger K value of the more volatile component is in the numerator and the smaller K of the less volatile component is in the denominator.О‘ is a unitless quantity. Thus, a K value (= y / x) for a more volatile component is larger than a K value for a less volatile component. Isobutane, and Propane having a vapor pressure of 52 psig at 70 F such.Relative volatilities are used in the design of all types of distillation processes as well as other separation or absorption processes that involve the contacting of vapor and liquid phases in a series of equilibrium stages.Relative volatilities are not used in separation or absorption processes that involve components reacting with each other (for example, the absorption of gaseous carbon dioxide in aqueous solutions of sodium hydroxide).For a liquid mixture of two components (called a binary mixture) at a given temperature and pressure, the relative volatility is defined as= the relative volatility of the more volatile component i to the less volatile component j= the vapor-liquid equilibrium concentration of component i in the vapor phase= the vapor-liquid equilibrium concentration of component i in the liquid phase= the vapor-liquid equilibrium concentration of component j in the vapor phase= the vapor-liquid equilibrium concentration of component j in the liquid phase= K commonly called the K value or vapor-liquid distribution ratio of a componentWhen their liquid concentrations are equal, more volatile components have higher vapor pressures than less volatile components. The table below shows propane vapor pressures at various outside temperatures.

K values are widely used in the design of large-scale distillation columns for distilling multi-component mixtures in oil refineries, petrochemical and chemical plants, natural gas processing plants and other industries. The values of K have been correlated empirically or theoretically in terms of temperature, pressure and phase compositions in the form of equations, tables or graph such as the well-known DePriester charts. In that context, a lighter component means a component with a lower boiling point (or a higher vapor pressure) and a heavier component means a component with a higher boiling point (or a lower vapor pressure).Thus, for the distillation of any multi-component mixture, the relative volatility is often defined asLarge-scale industrial distillation is rarely undertaken if the relative volatility is less than 1.05.
