Question
3- A 400 litres CSTR and a 1000 litres PFR are available to processes 1 litre per second. The feed contains 41 % A, 41 % B and 18 % inert. The irreversible gas phase reaction: A+B—C is to be carried out at 10 atm and 227 °C. The rate of reaction in gmol/L.min is given below as a function of conversion: -IA 0.2 0.0167 0.00488 0.00286 0.00204 X 0 0.1 0.4 0.7 0.9 (a) What is the maximum conversion that can be achieved with these two reactors connected in series? (b) What would be the overall conversion if two 400-L CSTRs were connected in series for the same feed and operating conditions? (c) What would be the overall conversion if two 400-L CSTRs were connected in parallel with half of the feed going to each reactor? (d) What is the volume of a single tubular reactor necessary to achieve 60% conversion if the molar feed rate is 2 gmol A/min? (e) If the total pressure were reduced by a factor of 10, would the conversion increase, decrease, or remain the same?
