In Example 12-1 we studied the four different types of heat exchanger on an exothermic reaction. In this section we carry out the same study on an endothermic reaction.
Example 12-2. Production of Acetic Anhydride
Jeffreys,2 in a treatment of the design of an acetic anhydride manufacturing facility, states that one of the key steps is the endothermic vapor-phase cracking of acetone to ketene and methane:
CH3COCH3 → CH2CO CH4
He states further that this reaction is first-order with respect to acetone and that the specific reaction rate can be expressed by
where k is in reciprocal ...
