QUESTION 1
The following elementary irreversible liquid phase reaction takes place in an isothermally
operated CSTR:
A + B → C
The feed enters the 175 L CSTR at a temperature of 27°C. The volumetric flow rate to the reactor
is 2 L/s. The feed is composed of 50% species A and the rest species B. The feed concentration
of species A is 0.1 mol/L. The pressure drop across the reactor is negligible.
The same reaction is to be carried out in a 100 L CSTR with the same feed flow rate, composition
and concentration as the 175 L CSTR.
(a) Determine the temperature at which the 100 L CSTR should be operated at in order to achieve
the same conversion as the 175 L CSTR.
(b) Is the 100 L CSTR suitable if the maximum operating temperature of the reactor is 45°C.
Additional Data
K = 0.83 L/mol.s at 293 K
E = 41 850 J/mol
R = 8.314 J/mol.K = 0.082 L.atm/mol.K = 0.082 m³.atm/kmol.K
