Use of Chemcad simulator for modelling heterogeneous azeotropic distillation of water and ethanol-containing mixtures
Sepn. of ternary H2O-EtOH-hydrocarbon mixts. by heteroazeotrope distn. to pure EtOH and the dry EtOH-hydrocarbon (95:5 by mole) mixt. was simulated by using 3 usual models and the NRTL model fitted with reliable vapour-liq.-liq. equil. data. The best agreement with exptl. data was achieved in the last case. A homogenous azeotrope was predicted in the H2O-EtOH-PhMe system.
