ABSTRACT

Chemical engineering thermodynamics deal with real substances whose properties are not entirely known from experiment at all possible temperatures and pressures. The model equations used in chemical engineering thermodynamics include volumetric equations of state that interrelate pressure, volume and temperature, and equations that relate activity coefficients to compositions. The main objective of this chapter is to provide readers with various thermodynamic models and corresponding MATLAB® programs that have already been found useful in academic and industrial applications. In this chapter, MATLAB programs are presented for the computation of equation of state, thermodynamic properties of fluid, fugacity coefficient, vapor pressure, activity coefficient, and vapor–liquid equilibrium. The MATLAB programs in this chapter can be used in undergraduate or graduate courses on chemical engineering thermodynamics, provided that students have a prerequisite understanding of the fundamentals of chemical engineering. Researchers and practicing engineers in the field of chemical engineering can use these MATLAB programs in the modeling and simulation of chemical processes.
