“…While simulations allow tuning of the design variables (operating conditions) for a specified flow sheet, to meet the desired design specifications, they provide Vaswal and Pugi (1975) little insight for generating alternative flowsheet configura- The necessary and sufficient condition for azeotropy in a vapor-liquid multicomponent reactive system is given by (Ung and Doherty, 1995~) X i = Y , , i = 1 , 2 ,..., c -r -1 , ('41) where X I and Y, are transformed mole fractions of component i in liquid and vapor phase, respectively.…”

-A correlation procedure for the prediction of vapor -liquid equilibrium of acetic acid -isopropanol -water -isopropyl acetate mixtures has been developed. It is based on the NRTL model for predicting liquid activity coefficients, and on the Hayden-O'Connell second virial coefficients for predicting the vapor phase of systems containing association components. When compared with experimental data the correlation shows a good agreement for binary and ternary data. The correlation also shows good prediction for reactive quaternary data.
