✦ Synopsis

A simultaneous heat and mass transfer model was applied to a binary system m a 3-m dtstdlatlon column packed with i m Raschlg Rings Mass transfer coefficients were obtained by measunng composmons and temperatures as functions of column height through use of the "dlfferentlal height" technique The experiments carried out with the toluene-tnchloroethylene system show that the hquld phase IS saturated indicating no resistance to mass transfer in the lquid phase Mass transfer coefficients obtained from the dlsullatlon experiments show agreement with mass transfer coefficients predicted from correlations of gas absorption data Bmary dlstlllatlon m contmuous contact equipment was modeled as a simultaneous heat and mass transfer
