D1. A very large distillation column is separating p-xylene (more volatile) from o-xylene. The column has two feeds (similar to Figure 4-17, but without the side stream). Both feeds are saturated liquids. Feed 1 is 42mol% p-xylene, F1=90 kmole/hr. Feed 2 is 9mole % p-xylene, F2=20 kmole/hr. The bottoms product should be 97% o-xylene and the distillate product should be 99% p-xylene. Find the flows rate D and B.



The overall mass balance

F_1+F_2=B+D (1-1)

90[kg/min]+20[kg/min]=B+D (1-2)

110[kg/min]=B+D (1-3)
