We plan to separate a mixture of propane and n-hexane at 300 kPa.

a. Using the data in the DePriester charts, plot ypropane VS. Xp Xpropane for this mixture at 300 kPa. Xpropane and T vs.

b. If the feed is 30.0 mol% propane, and V/F = 0.40, what are the liquid and vapor mole fractions and the drum temperature? Solve graphically. 0.80 and the feed is Zpropane = 0.60, what is the value of V/F?

d. Use the Rachford-Rice equation to check the answers obtained in parts b and c.

a. Using the data in the DePriester charts, plot \(\mathrm{y}_{\text {propane }}\) vs. \(\mathrm{x}_{\text {propane }}\) and \(\mathrm{T}\) vs. \(\mathrm{x}_{\text {propane }}\) for this mixture at \(300 \mathrm{kPa}\).

b. If the feed is \(30.0 \mathrm{~mol} \%\) propane, and \(\mathrm{V} / \mathrm{F}=0.40\), what are the liquid and vapor mole fractions and the drum temperature? Solve graphically.

c. If \(\mathrm{y}_{\text {propane }}=0.80\) and the feed is \(\mathrm{z}_{\text {propane }}=0.60\), what is the value of \(\mathrm{V} / \mathrm{F}\) ?

d. Use the Rachford-Rice equation to check the answers obtained in parts \(b\) and \(\mathrm{c}\).
