Absbxct

-A srmple calculation procedure IS developed which permits the predlcuon of bubble-pomt composltions from dew-pomt measurements for ternary systems at low pressures The proposed method IS equally apphcable to Isothermal and lsobanc data It does not requue any calculation of bquld acttvlty coefficients and their correlation by means of an Integrated Gibbs-Duhem equation. nor does It requue any supportmg physlcal propertles of the pure components constltutmg the ternary system Cakulatlon of the bubble-pomt composltlons from the dew-pomt data for the ternary system methyl ethyl ketone-rr-heptane-toluene at 760 torr IS camed out to serve as an ~lIustrat~on of the proposed method
