Problem
The following liquid-phase reaction is carried out in a CSTR with heat
exchange:
A + B
The feed stream contains A and B in equimolar ratio. The total molar
flow rate is 20 mol/s. The inlet temperature is 325 K, the inlet
concentration of A is 1.5 molar, and the ambient temperature in the heat
exchanger is 300 K.
Calculate the reactor volume necessary to achieve 80% conversion.
Additional information
U= 80 J/m2 s K
= 150 J/mol K
Cpc
E=25,000 J/mol
k298 = 0.014 L/mol-s
A=2 m?
AHRxn(298) = -10,000 J/mol
CPA= CPB= 100 J/mol K
