Problem 10.12: Use the SRK equation to calculate the Pxy graph of carbon dioxide (1)/normal pentane at 250 K. For this system k12 = 0.12.

a) Plot the Pxy graph at 250 K.

b) A stream contains a mixture of the two components with overall composition z1 = 50%. The conditions are 15 bar, 250 K. What is the phase of the system?

c) The above stream is flashed isothermally to a pressure such that the vapor contains 90% carbon dioxide. Determine the pressure and the concentration of CO2 in the liquid.
