HW

Due Date: 3:00PM on March 13, 2018

Generate a robust programming to solve the problem below. The program can be wrote by using any computer language, e.g., Matlab, C, VB, Julia, Python.

Grading:

Bring your laptop and successfully run your program to the instructor;

Be able to answer all the technical questions given by the instructor;

Be able to run other flash calculations when the conditions are changed, e.g., different composition, pressure, temperature;

Problem:

Use the Peng-Robinson equation of state to calculate the compositions and densities of the equilibrium liquid and gas of the mixture given below at 160F and 2000 psia. Use binary interaction coefficients of 0.02 for methane-n-butane, 0.035 for methane-n-decane, and 0.0 for n-butane-n-decane.

Component	Composition, mole fraction
Methane	0.5532
n-Butane	0.2630
n-Decane	0.1838
	1.0000

Compare your answer with experimental results shown below.

Component	Composition, mole fraction
	liquid	gas
Methane	0.458	0.856
n-Butane	0.304	0.130
n-Decane	0.238	0.0136
	1.000	0.9996
