Allyl chloride (AC) synthesis provides a simple prototype of many petrochemical processes. 869 kg per hour of propylene (C3) are fed with a 1% excess of chlorine (Cl2) at25�C. The entire process operates at roughly 10 bar. Cl2 is recycled to achieve a 50%excess of Cl2 at the reactor inlet. The reactor conversion is 100% of the propylene to ACand hydrochloric acid (HCl) at 511�C.The reactor effluent is cooled to 35�C and sent to a distillation column where 98%of the entering AC exits the bottom with 1% of the entering Cl2 and no HCl. This AC product stream exits at 57�C. The tops of the first column are sent to a second columnwhere 99% of the entering Cl2 exits the bottom at 36�C, along with 1% of the enteringHCl, all of the AC, and is recycled. The tops of the second column exit at -31�C andare sent for waste treating. a. Write a balanced stoichiometric equation for this reaction. (Hint: Check the NIST WebBook for chemical names and formulas.) b. Perform a material balance to determine compositions and flow rates for allstreams.
