Book Description
This work consists of three parts. The first part presents a thermodynamic framework for performing adiabatic flash calculations using continuous thermodynamics and an equation of state. The equation of state parameters and ideal gas heat capacities are correlated to molucular weight for five hydrocarbon homologous series. Illustrative examples are given for both single-stage and multistage calculations. The second part reports new measurements of high-pressure vapor-liquid equilibria for binary and ternary systems containing CO2, decane and tetralin at 71 and 104 degrees C. The third section presents a phenomenological correction to a classical equation of state to improve representation in the vapor-liquid critical region. The correction uses volume translation to locate the critical point and a nonclassical residual Helmholtz energy to account for density fluctuations near the critical point. Calculated phase equilibria and coexistent densities for pure components and binary mixtures are compared with experimental results.

Book Description
Excerpt from Vapor-Liquid Equilibrium of Binary Mixtures in the Extended Critical Region, Vol. 1: Thermodynamic Model There is, therefore, a need for a current and detailed explanation of the theory and techniques, which this report is intended to satisfy. The mostly self - contained exposition should be useful for a novice as well as for an individual, of either scientific or engineering background, experienced in phase equilibrium calculations. Although this first report of a series of two contains many new results and insights not published previously, the primary justification for the work is its wide - ranging success in correlating vle data as described in Part II of this series. Furthermore, the Leung - Griffiths formalism is in part rigorous thermodynamics and in part approximation and assumption. Some of our newly introduced parameters can be given heuristic justification, whereas others are purely empirical. The exposition is organized to make clear the logical structure of the method, to identify what is exact and what is approximate, and to present arguments justifying the approximations. In Sec. 2 we define the transformed variables of the Leung - Griffiths model and translate the fundamental laws of thermodynamics into relationships among these variables. The description to this point is general and devoid of assumptions and approximations. With the proper motivation, in Sec. 3 the equation specifying the independent variable (thermodynamic potential), as a function of the dependent variables, is constructed. This step corresponds in the conventional approach to the specification of an equation of state. Specific emphasis is placed on the conformity with simple scaling - law behavior and the thermodynamic consistency of the model. In Secs. 4 and 5, certain heretofore unspecified functions of the independent variables are defined explicitly. The representation of the critical locus in Sec. 6 completes the description of the model. New results and features are summarized in Sec. 7.
