A mixture of 100kg mol which contains 60 mol% n-pentane (A) and 40 mol% n-heptane (B) is vaporized at 101.32kpa pressure under differential conditions until 40kg mol are distilled. Use equilibrium data from example 11.3-2
x | 1 | .867 | .594 | .398 | .254 | .145 | .059 | 0 |
y | 1 | .984 | .925 | .836 | .701 | .521 | .271 | 0 |
1/(y-x) | 8.547 | 3.021 | 2.283 | 2.237 | 2.260 | 4.717 |
A) what is the average composition of the total vapor distilled and the composition of the remaming liquid? X2= .405 and yav=.892
B) If this same vaporization is done in an equilibrium or flash distillation and 40kg mol are distilled, what is the compostion of the vapor distilled and of the remaining liquid. x2=.430 and yav=.854
I just need to know how to get those values.
