Definitions
- the dispersing dispenser or receiver phase which are not soluble in the continuous exchange medium, are passed through chambers as droplets of drops.
- the exchange medium comes into contact in succession in the first chamber with the dispenser phase and in the second chamber with the receiver phase.
- the substance to be separated is moved from the first to the second chamber and from the
- the object of the invention is to open up further possible applications by modifying the known mass transfer process. These include processes with exchange media in different physical states and a coupling of absorption, adsorption and desorption processes in order to increase the separation efficiency of the mass transfer between two liquid phases.
