The Liquid/Liquid extraction unit demonstrates the separation of two liquid mixtures to be separated. The liquid mixture to be separated is delivered from the feed tank into the extraction column using a pump. There, it flows towards the solvent, which is also delivered into the extraction column by a pump. The mixture to be separated is made up of a transition component and carrier liquid. The carrier liquid and the solvent are insoluble in one another and therefore a phase boundary is established in the column. This can be observed and can be adjusted using valves. The movement of the transition component from the carrier liquid into the solvent occurs inside the column
