Scale-up of Electrolytic Reactors

Change in the scale of a reactor will change its performance. This calls for suitable allowances in process design knowledge of the probable variation in performance of units on a change of scale is required. For this we need mathematical models supported by key experimental trials. This section describes the procedures necessary to scale up an electrolytic reactor. 

Variations in mass transfer rates and current distribution due to the change in the scale of operation are emphasized.

It is common in the scale-up of electrolytic reactors to increase the number of smaller modules rather than go for an increase in electrode size. This may appear more costly in capital investment, but it is often more than compensated for by more efficient maintenance and process operation. Design limitations often make this the only choice.
