In the hydrodealkylation of toluene to produce benzene, 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 530°C enter a condenser where they are cooled to 45.0°C. A vapor stream containing 0.55 mol CH4/mol leaves the process, and a liquid stream containing 0.75 mol benzene/mol and 0.25 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at 800.0 mol/hr and contains 0.9000 mol benzene/mol and 0.1000 mol toluene/mol. The bottoms of the column contain 0.15 mol benzene/mol and 0.85 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at 1850 mol H2/hr. This process is carried out at 760 mmHg. Draw the process flow diagram and describe (label) it fully by solving for the unknown variables for all the streams. Calculate the Single Unit and Overall Conversion (%) of toluene.

a stream consisting of 44.6 mole% benzene and 55.4% toluene is
fed at a constant rate to a process unit that produces two product
streams, one a vapor and the other a liquid. The vapor flow rate is
initially zero and asymptotically approaches half of the molar flow
rate of the feed stream. Throughout this entire period, no material
accumulates in the unit. When the vapor flow rate has become
constant, the liquid is analyzed and found to be 28.0...

A stream containing toluene (T), heptane (H) and benzene (Z) is
fed into a distillation column at a rate of 200kmol/hr. The
composition of the feed has molar fractions for T of 0.4, H of 0.2,
Z of 0.4. The amount of toluene in the bottoms is 60% the amount of
toluene in the distillate. The molar fraction of hexane in the
bottom stream is 1/21 and the molar fraction of benzene in the
distillate is 2/19. Solve for the...
