Q (2). A membrane reactor is to be used for the production of phosgene in the gas phase: CO+Cl2COCl2A+BC The micro-reactor is 20mm long, 500m in diameter, and packed with cata-lyst particles 35 m in diameter. The entering pressure is 830kPa(8.2atm). and the entering flow to each micro-reactor is equimolar. The molar flow rate of CO is 2105mol/s and the volumetric flow is 2.83107m3/s. The weight of catalyst in one micro-reactor: W=3.5106kg. The reactor is kept isothermal at 120C. The rate law is given as: rA=kACACB (a) Plot the molar flow rates FA,FB and FC, the conversion X. and pressure ratio y along the length of the reactor. (b) Calculate the number of micro-reactors in parallel to produce 10000kg/ year phosgene. (c) How would your answer to part (a) change if the reaction were reversible with KC=0.4 dm3/mol?
