For a system composed of: n - pentane & n - heptane Antoine's Equation with pressure, P in kPa, Temperature, T in degrees Kelvin. P

For a system composed of: n-pentane & n-heptane
Antoine's Equation with pressure, P in kPa, Temperature, T in degrees Kelvin.
P(kPa)=101.325760.0exp[(A-BT(K)+C)]
Constants and Other Information:
\table[[Component,n-pentane,n-heptane]]
a) Using Antoine's Equation determif vapor pressures - at relevant temperatures (at temperatures between the boiling points of the two pure species)
b) Using Raoult's Law calculate and plot the Txy diagram at a total pressure of 101.325kPa.
c) Plot the xy data for this system at a total pressure of 101.325kPa.
n-Pentane / n-Heptane System.
A rectification column is fed 600kgmolehr of a mixture that is 46 mole % n-pentane -54 mole %n-heptane at 101.325kPa (abs) pressure. The distillate is to contain 94 mole % n-pentane and the bottoms 90 mole %n heptane. The reflux ratio is 3.0:1.0 or R=3.0.
a) Calculate the flowrates (molhr) of the distillate, D and bottoms, B.
Assuming that the feed mixture is a saturated liquid, e.g. vertical q-line ...
b) Determine the theoretical number of trays and the feed tray number for the specified operation.
c) Determine the minimum reflux ratio, RMIN and the minimum number of theoretical trays at total reflux. Assuming that the feed mixture is saturated vapor, e.g. horizontal q-line ...
d) Determine the theoretical number of trays and the feed tray number for the specified operation.
e) Determine the minimum reflux ratio. Rmin and the minimum number of theoretical travs at total reflux.
