D. Geana et V. Feroiu, CALCULATION OF VLE FOR SEMICONTINUOUS MIXTURES BY A GENERAL CUBIC EQUATION OF STATE, Revue Roumaine de Chimie, 39(11), 1994, pp. 1375-1387
One presents an extension of a general cubic equation of state (GEOS),
proposed in previous works, for applications to phase equilibria calc
ulations in mixtures containing very many components, based on continu
ous thermodynamics. For VLE calculations in continuous mixtures of par
affins, distribution functions of exponential and Gamma-type have been
used. Based on a component lumping upon Gauss numerical quadrature fo
rmulas, the usual VLE computer programs for discrete component mixture
s may be used. As examples, some dew-T and flash calculations in semic
ontimous mixtures of paraffins are discussed.
