1 PGE 312 - FALL 2010 Physical and Chemical Behavior of Petroleum Fluids I Final Examination, 3 Hours Closed Book & Notes It will be in your best interest to attempt all the questions. Please budget your time accordingly. Problem 1 (20 points) A binary gas mixture containing methane and ethane has a specific gravity of 0.75 relative to air. Calculate the composition of the gas in mole fractions. Atomic weight of carbon = 12. Atomic weight of hydrogen = 1.

2 Problem 2 (20 points) The physical properties of a pure hydrocarbon component are as follows: Saturated liquid density at 110 F = 29.33 lb mass/cu ft Saturated vapor density at 110 F = 1.87 lb mass/cu ft Vapor pressure at 110 F = 155 psia Molecular weight = 44.097 lb mass/lb mole Critical pressure = 616.0 psia Critical density = 13.76 lb mass/cu ft Critical temperature = 206.06 F Figure 1 shows 5 equilibrium states of this pure component marked on a Density – Temperature diagram. The states are numbered 1, 2, 3, 4, and 5. Figure 1. Density diagram for a pure component (not to scale).
