1. You are assigned to design a separation process to separate a chemical mixture that is comprised of J kmol/h of n-pentane and K kmol/h of n-hexane. You have chosen distillation process to separate the mixture, in which the feed contains L% saturated vapor and M% saturated liquid. The distillation column is equipped with a partial condenser and a total reboiler and is operating at atmospheric pressure. The overall tray efficiency is 74%. The product specifications are listed below: . distillate composition: P mol % of n-pentane bottom composition: Q mol % of n-hexane ● i. Determine the minimum number of trays (Nmin) using McCabe-Thiele's graphical method if the distillation column is operated at total reflux. ii. Estimate the number of trays needed in the distillation column if the reflux ratio is R. iii. Suppose the feed is in saturated liquid condition. Determine how will this different feed condition affect the number of trays/plates needed in the distillation column. J= 98.8 O=96 R=3.12 K=161.2 L=64 M=36 P=94

Transcribed Image Text:F. Task(s)
1. You are assigned to design a separation process to separate a chemical mixture that is
comprised of J kmol/h of n-pentane and K kmol/h of n-hexane. You have chosen
distillation process to separate the mixture, in which the feed contains L% saturated vapor
and M % saturated liquid. The distillation column is equipped with a partial condenser and
a total reboiler and is operating at atmospheric pressure. The overall tray efficiency is 74%.
The product specifications are listed below:
• distillate composition: P mol % of n-pentane
• bottom composition: Q mol % of n-hexane
i. Determine the minimum number of trays (Nmin) using McCabe-Thiele's graphical method
if the distillation column is operated at total reflux.
ii. Estimate the number of trays needed in the distillation column if the reflux ratio is R.
iii. Suppose the feed is in saturated liquid condition. Determine how will this different feed
condition affect the number of trays/plates needed in the distillation column.
