THERMODYNAMICS: Using MATLAB and an Equation of State of your own choice, evaluate the following:
Industrial applications routinely require knowledge of the phase diagram of a compound. Here you will consider the case of vapor-liquid equilibrium (VLE) of a one component system. The US National Institute of Standards and Technol- ogy (NIST) maintains a publicly available database of thermodynamic data at http://webbook.nist.gov/chemistry/fluid/. Select a species of interest from the drop down menu- you are free to choose whichever you want. Select Saturation Properties and explore the available data in the Java applet. Note that the data is available in tabular form if you uncheck the option to use the applet The auxiliary data (under the applet's plot) gives you critical parameters and an acentric factor. Choose an equation of state (e.g. Peng-Robinson) and use these parameters to calculate p your chosen EOS. This will require Matlab or a comparable tool. You can look up correlations online that specify the parameters a and b in terms of the temperature, the critical parameters, and the acentric factor. You must evaluate the saturation pressure for at least the following temperatures: T - 0.65Tc, 0.70Te, 0.75Tc, 0.80Tc,085Te, 0.90Tc. Compare your results to the NIST data by plotting both in the same plot. In the same plot, fit your p - T data using the August equation, and use the fit parameters to estimate the enthalpy of vaporization - T diagram for VLE predicted by Hand in your code, the output of your code, and a brief but clear explanation of what your code does. (The code alone is not sufficient explanation of what vou have done. Industrial applications routinely require knowledge of the phase diagram of a compound.
