Reactive Distillation is portrayed in the picture below.
To illustrate the effects of reactive distillation lets take the
Taking the reaction to be elementary, the rate law is :
In reactive distillation, one of the products is continually removed causing the concentration of the removed product to become very small. As a result the reverse reaction decreases and more product is formed.
Removing a component also has an effect on the mole balance. If
D is the only component being
removed, its mole balance becomes:
Again, the overall mass balance must be done. However, this time the flow of D out of the system must be taken into account.
The mass terms in the equation can be replaced by :
Assuming that the system is at constant density leads to :
|Mole Balance||Mass Balance|
