1 PGE 312 - FALL 2007 Physical and Chemical Behavior of Petroleum Fluids I Final Examination, 3 Hours It will be in your best interest to attempt all the questions. Please budget your time accordingly. Problem 1 (16 points) Fifty gms (50 gms) of a pure hydrocarbon is confined in a piston-cylinder vessel of volume 1000 cm 3 , maintained at a constant temperature of 200 F. The saturated liquid ˚ and saturated vapor densities of the hydrocarbon at 200 F are 0.45 gm/cm ˚ 3 and 0.05 gm/ cm 3 , respectively. The vapor pressure data for the pure hydrocarbon are given in Table 1. Table 1 Vapor Pressure Data for the Pure Hydrocarbon of Problem 1 Temperature Vapor Pressure ( F) ˚ (psia) 50.0 31.9 100.0 72.5 150.0 143.1 200.0 255.4 250.0 422.2 274.5 527.9 a. Calculate the mass of vapor in the vessel in gms.

2 b. Determine the pressure in the vessel in psia. Please explain the reasoning behind your answer in part (b) to get full credit. There will be no credit for guessing the correct answer without an appropriate explanation. c. If the pure hydrocarbon is expanded to a pressure of 100 psia at the constant temperature of 200 F, calculate the mass of liquid in the vessel in gms. ˚ d.. Using a dot ( . ), display the state of the hydrocarbon in part c on a P-V diagram at the fixed temperature of 200 F. Mark on your P-V diagram all the known ˚ numerical values of pressure in psia and all the known numerical values of volume in cm 3 . Problem 2 (15 points)
3 Sketch fully labeled diagrams to demonstrate your knowledge of the following phase diagrams: a. The P–V diagram for an ideal gas at a constant temperature. b.
