Organic solvent nanofiltration: a new frontier in the field of molecular separation

In the late 20th century, it was already possible to achieve molecular level separation using separation membranes in aqueous solutions, followed by reverse osmosisPermeation and nanofiltration achieve the separation of ions and other molecules. Until recently, both separation technologies were almost exclusively used for wastewater treatmentProcessing, desalination, and food and beverage industries.In the past decade, membrane separation (organic solvent nanofiltration) of molecules dissolved in organic liquids has become a scientific research in membrane separationThe new field of research has broad application prospects in the chemical related industry.This reflects the great benefits it contains. Why? Common purification processes such as distillation, extraction, chromatographic analysis, adsorptionCrystallization is either an energy intensive process, a raw material intensive process, or there may be stability issues. People generally believe that,“……The separation process accounts for a significant portion of industrial capital and operating costs40-70%……”.. We can perform a simple calculation, inConcentrate solutes in specific solvents10 times,useUnited NationsThe energy consumed by the process is less than that of thermal separation technology(Like distillation)of10%.Obviously,United NationsIt can significantly reduce costs.
