Abstract
An isoplethic phase envelope is a locus of two-phase equilibria where one of the phases is kept at constant composition. The thermodynamic conditions for such a phase envelope are expressed as a set of first-order ordinary differential equations in which molar concentrations appear as central variables instead of mole fractions. The resulting formalism is applicable to multicomponent mixtures, well-suited for machine calculations, and allows a very rapid calculation of phase envelopes with arbitrary equations of state.Application to the formalism to pure fluids yields simple differential equations that are analoga of Clapeyron's equation, but permit the calculation of orthobaric densities.
