2. Calculate the GR/RT and / (fugacity) values of hydrogen sulfide at 600 K and 25 bar using (a) Redlich/Kwong equation and (b) generalized correlation (Lee/Kesler)
3. A mixture of hydrocarbon contains 42 mol% methane, 35 mol% propane, and 24 mol% n-butane. If the material is flashed at 150°F at an absolute pressure of 140 psi, what fraction leaves the separator as liquid? What is the composition of the liquid and vapor?
4. A binary system of species 1 and 2 consists of vapor and liquid phases in equilibrium at temperature T. The overall mole fraction of species 1 in the system is z; -0.60 at temperature T. In yı = 0.85 x2 In y2 = 0.85 x, P1sat=42.3 kPa P2sat=79.7 kPa. Assuming the validity of the modified Raoult's Law,
(a) Determine the range of pressure that this system can exist as two phases at given T and z
(b) For liquid mole fraction xı = 0.47, find the pressure P and the molar fraction V of the system that is vapor
(c) Show whether or not the system exhibits an azeotrope. If an azeotrope is formed, find the azeotropic composition and pressure.
