Question
ANSWER PROBLEM 2 ONLY PLEASE.
Problem 1
A simple (i.e. single equilibrium stage) batch still is being used to separate benzene from o-xylene; a system which may be assumed to have a constant relative volatility of 6.7. The feed to the still is 1000 mol of 60 mol% benzene. The process is run until the instantaneous distillate composition is 70 mol% benzene. Determine:
a)the composition and amount of the residue remaining in the still pot
b)the amount and average composition of the distillate
c)the time required for the process to run if the boil-up rate is 50 mol/h
Problem 2
For the same system in Problem 1, the process is run until 50 mol% of the benzene originally in the still-pot has been vaporized. Determine
a)the amount of o-xylene remaining in the still pot
b)the amount and composition of the distillate
c)which of the runs takes longer
