Problem #3 (35%). Vinyl chloride is synthesized through the following reaction of acetylene and hydrochloric acid: C2 H2 + HCl –→ CH2CHCI The following undesired reaction also occurs simultaneously, producing dichlorethane instead: C2 H2 + 2HCI C2 H4C12 These reactions occur in a reactor during the manufacture of vinyl chloride. In this process, the feed to the reactor contains 100 Kmol/h of acetylene. The same feed also contains HCI, 16% in excess of that needed if the desired reaction went to completion, as well as 1.2 Kmol/h of an inert contaminant (water vapor). The single-pass fractional conversion of acetylene in the reactor is 12%, and 94% of the C2H2 so reacted is consumed in the first reaction to form vinyl chloride. The only stream leaving the reactor goes to a separation unit where all the vinyl chloride and all the dichlorethane are condensed and removed through a bottom liquid stream. This liquid stream contains nothing else. The top gaseous stream from the separator is split between a purge stream that leaves the process and a recycle stream that is combined with the fresh feed to the process to form the feed to the reactor. The fresh feed to the process contains 0.1 mole% of the inert contaminant. Draw a schematic and balance the whole process. You are not required to conduct a DOF analysis. Recommended Approach:

One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene. C,H,CH; + H, C,H, + 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 550 °C enter a condenser, where they are cooled to 41.0 °C. A vapor stream containing Y5CH, = 0.600 mol CH,/mol leaves the process, and a liquid stream containing x66 = 0.810 mol benzene/mol and x6 = 0.190 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at n7 = 668.0 mol/h and contains y7h = 0.9000 mol benzene/mol and y7 = 0.1000 mol toluene/mol. The bottoms of the column contains X8b = 0.250 mol benzene/mol and xgt = 0.750 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at ni = 1183 mol H,/h. This process is carried out at 760 mmHg. A n, mol/h mol H/mol YSH2 YSCH, mol CH_/mol Ysh mol b/mol Ys mol t/mol n̟ mol/h n, mol/h Condenser Улн, тol H/mol Усн,…

#3 The first step in the reaction sequence for the production of nitric acid via the oxidation of ammonia is: 4NH3 + 502 2 4NO + 6H2O 75% conversion is achieved with an equimolar mixture of ammonia and oxygen fed at the rate of 100 mol/h. Determine the outlet compositions. (Hint: determine the limiting reactant).
