Description

This notebook uses two methods to compute the equilibrium constants at T=300 K and P=3.5 bars for a mixture of propane, n-butane, iso-butane, iso-pentane and n-pentane. Then, the Rachford-Rice Equation is solved to compute the fraction vaporized when the feed is 20 mole % propane, 30 mole % n-butane, 40 mole % iso-butane, 5 mole % n-pentane and 5 mole % iso-pentane. Finally, both liquid and vapor phase compositions are calculated.
