Determination of the transfer unit, TU

Relation between number of theoretical stages %), and transfer units TU 

I Operating line steeper than equilibrium curve 

Comparison between the theoretical number of separating stages tti, and the transfer unit TU 

On the assumption that the resistance to transfer is associated with the vapour phase only the number of transfer imits is defined by 

Corresponding to the height of a separating stage, colimn length equivalent to a theoretical plate, (HETP), (122)
