Question

Print Calculator Periodic Table Question 8 of 8 One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene 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 520°C enter acondenser where they are cooled to 40 0. A vapor stream containing 0.570 mol CH4/mol leaves the process, and a liquid stream containing O.800 mol benzene/mol and 0.200 mol toluene/mol enters a distillation column. The distillate of the column leaves the contains 0.9200 mol benzene/mol and 0.0800 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 1347 mol Hz/hr.

Explanation / Answer

Answer:

1. The mole fraction of benzene and toluene leaving in vapor stream

y5b=0.12 , y5t=0.08

2.The flow rate of fresh toluene in the feed stream

n2=1526 mol/hr

3. The flow rate of recycle stream n8 = 45 mol/hr

4. Conversion of toluene into product in the reactor is 82.5%
