Notes:
The continuous-lumping method is a refinement of continuous thermodynamics which does not depend upon the continuous-mixture hypothesis. The method utilizes a generalized Fourier series expansion of a functional formulation of the equilibrium relations obtained by embedding the classical discrete equilibrium equations into generalized function space. The resulting method provides an effective means of reducing the number of parameters needed to describe a many-component, complex mixture; furthermore, the method provides a straightforward means of converting the equilibrium equations to the new parameterized form. The error associated with the reduction in number of parameters can be easily estimated using the ratio convergence test for mathematical series. The theory of the method is first presented and the method is then used in an example calculation to illustrate the advantages of the method over pseudocomponent lumping and continuous thermodynamics. The method is useful particularly for mixtures described by chromatographic data.
