One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene
C6H5 CH3 + H2 -> C6H6 + CH4
A stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen. The reaction products at 510°C enter a condenser where they are cooled to 44.0°C. A vapor stream containing 0.550 mol CH4/mol leaves the process, and a liquid stream containing 0.670 mol benzene/mol and 0.330 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at 625.0 mol/hr and contains 0.9500 mol benzene/mol and 0.0500 mol toluene/mol. The bottoms of the column contain 0.200 mol benzene/mol and 0.800 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at 1284 mol H2/hr. This process is carried out at 760 mmHg.
1.What are and the mole fractions of benzene (b) and toluene (t) respectively, in the vapor stream leaving the condenser?
2.What is n2, the flow rate of fresh toluene into the process?
