Zum Flutpunkt in Flüssig/Flüssig‐Gegenstromkolonnen

Flooding point of liquid‐liquid countercurrent columns. Calculation of the column diameter for given volumetric flow rates of the raffinate and the extract phases requires a knowledge of the flooding point. A simple flooding point diagram is presented which contains the rise or fall rate of an individual drop as intermediate quantity. The principal experimental results from the literature obtained in countercurrent columns with and without introduction of energy by rotation and pulsation are compared with the flooding point diagram.
