Thermodynamics of Multicomponent Mixtures

In agreement with the phase rule for single-phase behavior, if [Pg.53]

Standard thermodynamic formalism for the total differential of specific enthalpy in terms of its natural variables (i.e., via Legendre transformation, see equations 29-20 and 29-24b) allows one to calculate the pressure coefQdent of specific enthalpy via a Maxwell relation and the definition of the coefficient of thermal expansion, a. [Pg.53]

The pressnre coefficient of specific enthalpy is identically zero for ideal gases, but the thermal energy balance must include a pressure contribution for other fluids. The partial derivative of /i in the summation of (3-22), dh/dcoi)T,p, aii [Pg.53]

The mass balance for a differential plug-flow reactor (equation 3-17) that operates at high-mass-transfer Peclet numbers allows one to replace dtw, in (3-32)  [Pg.54]

Now the total differential of specific enthalpy contains a chemical reaction contribution via the kinetic rate law 3R  [Pg.54]

Another approach is to employ rigorous statistical thermodynamic theories. In this paper, the Kirkwood-Buff (KB) theory of solutions (fluctuation theory of solutions) is employed to analyze the thermodynamics of multicomponent mixtures, with the emphasis on quaternary mixtures. This theory connects the macroscopic properties of re-component solutions, such as the isothermal compressibility, the concentration deriva-... [Pg.179]
