For a deethanizer distillation column depicted in the figure below, estimate the actual number of stages, assuming it is equal to 2.5 times Nmin. Clearly indicate what are the light and heavy key components for this problem. Next, find the ideal feed stage location. Lastly, find the composition of the C1 component in the distillate using the Fenske equation. Here, Nmin is the minimum number of equilibrium stages estimated using the Fenske method under total reflux conditions. min In X B/Dist B/R In[A] AB In Dx A DX 8/Dist BXA A BXBR In[s] N N (N)min N min 90F Comp. kmol/h C C C nC nC5 55555 160 370 240 25 5 2 kmol/h of C3 a, average Comp. relative volatility 8.22 2.42 1.00 0.378 0.150 55555 2 kmol/h of C For a deethanizer distillation column depicted in the figure below, estimate the actual number of stages, assuming it is equal to 2.5 times Nmin.
