摘要 |
The present invention concerns a way to achieve in liquid-liquid extraction in the step of dispersing two different solution phases the transformation of the desired phase, which may also be the phase with smaller volume, to become the continuous phase, with the aid of a primarily vertical circulation flow. The invention also concerns an apparatus serving this purpose, a circulation dispersion contactor, in which the smooth circulation of the dispersion is accomplished by the aid of a radial pump turbine designed for this particular purpose, or of an axial propeller, and of distribution/guide rings on the periphery of the contactor. |
