Vapor-Liquid Equilibrium Calculations Using K Values

For light hydrocarbon systems (methane to decane), the K values have been determined semi-emperically and can be evaluated from the equations given in Table 3.13. In general, K is a function of temperature, pressure, and composition. Table 3.1. Equilibrium K values for light hydrocarbon systems ===== (1) ln K = -A/T2 + B - C ln(P) + D/P2 ................
