(20 points) Distillation column A distillation process is conducted with an input stream at 2000 kg/h containing a mixture of benzene (B) and toluene (T) with 60% B by mass and it is separated into two output fractions, each containing (B) and (T). The mass fraction of B in the output top stream is 0.7 and the mass fraction of B in the output bottom stream is 0.35. The operation is at steady state. Assume 3 significant figures throughout. (a) Draw and label a process flow diagram and define the system boundary. (b) Write mass balances on B and T to calculate output stream mass flow rates
