Heads and tails separation factors α, β are multiplicative measures of separation concerning the desired material's enriched and depleted streams. The function trans-forming multiplicative quantities to additive ones is a logarithm, and additive measures of separation concerning the desired material become In α and In (1/β) for the enriched and depleted streams, respectively. The additive measure of separating element is the weighted sum of them and the weights are selected to be portions of the desired material moving towards the enriched and depleted streams η and η:<BR>which equals to the separative power relevant to the desired material per unit flow rate. Similarly, the additive measure relevant to the undesired material becomes<BR>Thus, the functions representing separative power wt, and cos are additive measures of separating element relevant to the desired and undesired materials, respectively. More-over, ψ<SUB><I>b</I></SUB> and ψ<I><SUB>a</SUB></I> are equivalent and distinguished only by the selection of the desired material in the two components in a binary mixture.
