Preferred Label : enrichment factor;
Detailed label : enrichment factor in liquid-liquid distribution, S;
IUPAC definition : The factor by which the ratio of two substances in the feed must be multiplied to
give their ratio after treatment. \[\frac{Q_{{A}}}{Q_{{B}}} S_{{A,B}}\ \frac{Q_{{A}}
{'}}{Q_{{B}} {'}}\] where QA and QA' are the final and initial amounts of species
strong A /strong and QB and QB' are the final and initial amounts of species strong
B /strong . Hence S A,B E A E B where E is the fraction extracted. In terms of D,n,r
(where n is the number of stages and r the phase ratio), \[S_{{A,B}} \frac{1- (1\,
\,r\ D_{{A}}) {-n}}{1- (1\, \,r\ D_{{B}}) {-n}}\];
