Calculation Of Number Of Stages To Separate Benzene Toluene Mixture

Question

An equimolar mixture of benzene and toluene is separated in a sieve plate tower at the rate of 50 kg mole/hr. The overhead product contains 95% benzene and a bottom product of 2.4 mole% of benzene. The feed is a mixture of 3/5 vapor and 2/5 liquid. The equilibrium data is given below.

 
x    0    0.1    0.2      0.30    0.4      0.5     0.80    1       
y    0    0.2    0.37    0.51    0.62    0.78    0.90    1    

Where x and y are mole fractions of benzene in liquid and vapor respectively. Determine the actual number of stages and the location of the feed tray.

Summary

The question belongs to Chemistry and it discusses about calculating the number of stages and location of feed tray for separating benzene and toluene mixture.
