2.10 Irreversible consecutive reactions A B Coccur in
a jacketed, stirred-tank reactor as shown in Fig. E2.10. Derive a
dynamic model based on the following assumptions:
(i) The contents of the tank and cooling jacket are well
mixed. The volumes of material in the jacket and in the tank
do not vary with time.
(ii) The reaction rates are given by
n = K¡2¯E\/RTCA [=] mol A/h L
%3D
12=kze-E2/RT,
CB = mol B/h L
%3D
(iii) The thermal capacitances of the tank contents and the
jacket contents are significant relative to the thermal capaci-
tances of the jacket and tank walls, which can be neglected.
(iv) Constant physical properties and heat transfer coeffi-
cients can be assumed.
Note:
All flow rates are volumetric flow rates in L/h. The concentra-
tions have units of mol/L. The heats of reaction are AH and
AH2.
