Work Prob. 13.51 for the NRTL equation. Prob. 13.51 For the acetone(1)/methanol(2)/water(3) system, based on Eq. (13.19)

Question:

Work Prob. 13.51 for the NRTL equation.

Prob. 13.51

For the acetone(1)/methanol(2)/water(3) system, based on Eq. (13.19) and the Wilson equation, make the following calculations:
(a) BUBL P : t = 65°C, x1 = 0.3, x2 = 0.4.
(b) DEW P : t = 65°C, y1 = 0.3, y2 = 0.4.
(c) P, T − flash : t = 65°C, P = ½ (Pbubble + Pdew), z1 = 0.3, z2 = 0.4.

Problems 13.43 through 13.54 require parameter values for the Wilson or NRTL equation for liquid-phase activity coefficients. Table 13.10 gives parameter values for both equations. Antoine equations for vapor pressure are given in Table B.2, Appendix B.
