ABSTRACT:
The presence of carryunder in the extract phase recovered from a solvent extraction tower is an indication of unsatisfactory performance. The continuous analysis of the extract phase using a turbidity analyzer to detect the presence of two phases, indicating carryunder permits corrective measures to be taken in tower operation to reduce or eliminate carryunder.
