A continuous column flash system (Figure 4-24) is separating (100 mathrm{kmol} / mathrm{h}) of a saturated liquid

Question:

A continuous column flash system (Figure 4-24) is separating \(100 \mathrm{kmol} / \mathrm{h}\) of a saturated liquid feed that is \(45 \mathrm{~mol} \%\) methanol and \(55 \mathrm{~mol} \%\) water at \(1.0 \mathrm{~atm}\). Operate with \(\mathrm{L} / \mathrm{V}=1.5\) and the outlet bottoms at \(\mathrm{x}_{\mathrm{N}}=0.28\). Data are in Table 2-1 and Problem 3.E1.

a. Find the values of \(\mathrm{F}_{\mathrm{L}}, \mathrm{F}_{\mathrm{V}}, \mathrm{y}_{1}\), and the number of equilibrium stages required.

b. Find the value of \(\mathrm{Q}\) used to vaporize \(\mathrm{F}_{\mathrm{V}}\).

c. For a normal flash with the same feed and the same V/F, find the values of \(\mathrm{x}\) and \(\mathrm{y}\).


Problem 3.E1.
