A mixture of benzene, toluene, and xylene enters a two-stage distillation process where some of the componentsare recovered. The distillation process operates at steady-state conditions with operating information as shown inthe table. In addition, the following information is known about the distillation process:
98.0% (by weight) of the xylene that enters Column A in the feed stream (Stream 1) leaves in the intermediate stream (Stream 3)
96.0% (by weight) of the benzene that enters in the feed stream (Stream 1) leaves in the top stream from Column B (Stream 4)
Find a set of independent equations that canbe solved for all the unknowns. Clearly identify
the unknowns and identifyyour equations. Solve for the unknowns.
