Abstract:
The present invention describes a liquid-liquid extraction column with perforated plates and downpipes, having a majority of so-called “open” plates and a minority of so-called “closed” plates, the two types of plates differing in the degree of perforation. Application of the said column to the treatment of liquid-liquid systems with time-variable coalescence.
