  • Solvent Extraction an overview | ScienceDirect Topics

    Solvent extraction is the process in which a compound transfers from one solvent to another owing to the difference in solubility or distribution coefficient between these two immiscible (or slightly soluble) solvents Compared with other separation methods, it gives a better separation effect than chemical precipitation, and a higher degree of selectivity and faster mass transfer than the ionSolvent extraction also has the advantage of low energy consumption, compared to solvent distillation However, solvent distillation can provide many environmentallyfriendly benefits as well, especially when used as part of a Closed Loop Recycling and Recovery system At Temarry Recycling, solvent distillation is part of the circular economy because nothing is wasted and a marriage is createdHow Does Solvent Extraction Work? Temarry RecyclingBy destroying internal binding forces, pressurized solvent extraction which brings great improvement to extraction performance [6,7] Considering ideal extraction results have been achieved due to the structural similarity between the target compounds and extractant in our previous work (as the extended rule of “like dissolves like”) , a unique selective extraction way for the highlyA targeted extraction with solventfree pressurized method
