CE 620 Liquid-Liquid Extraction Didactic Equipment Vocational Training Equipment Fluid Lab Equipment
Separation of a two-component liquid mixture by extraction in counterflow with a solvent Features - separation of a liquid mixture by liquid-liquid extraction in counterflow operation - enrichment of extract using integrated distillation column - operation in either continuous or discontinuous process mode is possible - design and materials allow investigation of different ternary systems - adjustment and observation of phase boundary possible Learning objectives/experiments - transition of a component from a two-component liquid mixture into a solvent by extraction - scale-up from beaker experiment to pilot plant scale - enrichment of transition component in extract by distillation - evaluation of separation processes via concentration measurement and mass balances - influence of different experimental options on separation processes Specification [1] liquid-liquid extraction in counterflow operation with distillation for enrichment of the extract [2] operation as continuous or discontinuous process using 2 three-way valves [3] glass extraction column [4] distillation column and distillation bridge with Liebig condenser [5] electrical bottom heating via PID controller [6] water jet pump for reduction of evaporation temperature during distillation [7] stainless steel tanks for feed, solvent, raffinate, extract and top product (distillation) [8] 2 pumps to deliver the feed and solvent [9] 2 valves for adjusting the phase boundary [10] distillation column packed with Raschig rings [11] accessories housed in a storage system with foam inlay
