Stream (1) is the feed to a distillation unit where the separation takes place according to the following
specifications:
1.98% of the benzene leaves with the distillate stream (stream #2).
2.99% of the toluene in the feed leaves with the bottoms stream (stream #3)
3.100% of the xylenes in the feed leaves with the bottoms stream (stream #3).
Assuming that the volumes of components are additive, and using the densities of pure components from
Table I in the Appendix, compute the concentration and volumetric flow rate of the distillate (stream #2)
and bottoms (stream #3) stream leaving the distillation unit.
