Solvent dehydration becomes more difficult when a solvent-water mixture approaches an azeotrope. Adding theoretical stages or increasing reflux may no longer achieve the required water specification because vapor-liquid equilibrium limits the separation available from conventional distillation. Azeotropic distillation and extractive…
Producing battery-grade lithium bis(fluorosulfonyl)imide (LiFSI) requires control beyond final assay. Crude material can contain moisture, acidic species, chloride, fluoride, sulfate-related impurities, metals, insoluble solids, and process solvents that respond differently to purification operations. Crystallization can contribute to both impurity rejection…
Static mixers blend, disperse, contact, react, or thermally condition process streams without mechanically driven agitation. They are used in continuous chemical processing, polymer production, water treatment, and other applications where mixing must occur directly within a flowing stream. Selecting a…
