Aspects of the Amalgam Decomposer

We may now consider the energy and material balance [2] associated with the decomposition tower, shown in Fig. 4.9.4. The voltage balance of the tower can be represented as  

The amount of caustic produced, dw, in a small section of height, d, is  

Chilton and Colburn have employed the idea of the number of transfer units (NTU) and the height of the transfer unit (HTU) to describe packed colunms [3] according to which the height, H, is represented by the product  

The value of NTU can be evaluated using Eq. (15), if the concentration of caustic soda solution and the operating temperature are kept constant. 

An empirical relation, obtained with laboratory and plant data [2], relating to the various operating parameters, is given by
