Question

One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene. C6 H5 CH3 + H2 righyarrow C6 H6 + CH4 Stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen, i ne reaction products at 540 degree C enter a condenser where they are cooled to 49.0 degree C. A vapor stream containing 0.520 mol ChVmol leaves the process, and a liquid stream containing 0.730 mol benzene/mol and 0.270 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at 635.0 molyhr and contains 0.9400 mol benzene/mol and 0.0600 mol toluene/mol. The bottoms of the column contain 0.220 mol benzene/mol and 0.780 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at 1590 mol H2/hr. This process is carried out at 760 mmHg.
