Relative volatilities or enrichment ratios are defined as the ratio of two K-values and are usually denoted by the symbol αij , e.g., αij = Ki / Kj For vapor-liquid-equilibrium, the K-value is defined as: Ki = yi / xi where yi and xi are the mole fractions of component i in the vapor and liquid phases.
