CE 561 Homework 10: Assigned 11/11/09, due 11/16/09 (1) (adapted from Chemical Reaction Engineering and Kinetics by Missen, Mims, and Saville) Calculate the total reactor volume required, in an adiabatic ideal plug-flow reactor, to achieve 60% fractional conversion of Cl 2 and a total vinyl chloride production rate of 10 kg/hr in the steady-state production of vinyl chloride from chlorine and ethylene via the gas phase reaction: Cl 2 + C 2 H 4 → C 2 H 3 Cl + HCl The molar ratio of ethylene to chlorine in the feed is 20. The reactor operates at a pressure of 1 bar. The feed enters the reactor at 593 K. For similar conditions, with a large excess of ethylene, the reaction was reported to be pseudo-first order in Cl 2 and the measured pseudo first order rate constant at several temperatures was as follows: T (K) 593 613 633 653 k (1/s) 2.23 6.73 14.3 32.6 Suggest an appropriate length and diameter for an empty tubular reactor to carry out this reaction, if the Reynolds number in the reactor should be at least 10,000 to ensure
