3. A mixture of 0.30 mole fraction benzene and the rest toluene is fed to a continuous distillation column to give an overhead product of 0.90 mole fraction benzene and a bottom product of 0.95 mole fraction toluene. The feed enters at 283 K with a specific heat capacity (Cp) of 1.84 kJ/kg K and a boiling point of 374.7 K. The latent heat of vaporisation (1) of the feed is 30 MJ/kmol. If the reflux ratio is 5.0, a. How many theoretical plates are required? b. How many actual plates are required assuming a plate efficiency of 80 percent?

Question
Transcribed Image Text:3. A mixture of 0.30 mole fraction benzene and the rest toluene is fed to a continuous distillation
column to give an overhead product of 0.90 mole fraction benzene and a bottom product of
0.95 mole fraction toluene. The feed enters at 283 K with a specific heat capacity (Cp) of
1.84 kJ/kg K and a boiling point of 374.7 K. The latent heat of vaporisation (1) of the feed
is 30 MJ/kmol. If the reflux ratio is 5.0,
a. How many theoretical plates are required?
b. How many actual plates are required assuming a plate efficiency of 80 percent?
