Liquid-Liquid Extraction Columns Manufacturers
Mathesis Engineers Liquid-Liquid Extractors (Solvent Extraction Columns) are engineered to separate dissolved chemical mixtures using two immiscible liquid phases, delivering high stage efficiency and energy-efficient solvent purification.
Liquid-Liquid Extraction (LLE) is a thermal-free separation process used when distillation is economically unfeasible due to close boiling points, azeotropes, or heat sensitivity. Mathesis Engineers manufactures Scheibel Columns, Karr Reciprocating Columns, Agitated Discs, and Packed Liquid Extractors.
Engineered with high mass transfer agitation internals, precision phase settlers, and automatic interface level controls, our liquid extractors deliver sharp separation with low solvent-to-feed ratios.
Two immiscible liquid phases (heavy feed phase and light solvent phase) enter counter-currently at opposite ends of the vertical extraction column. Internal agitated impellers or packing break the dispersed phase into fine droplets.
Solute transfers from the feed droplets into the continuous solvent phase due to chemical affinity. The phases separate at top and bottom settling zones driven by density difference, discharging extract and raffinate streams continuously.
High Theoretical Stage Count
Achieves multiple equilibrium stages in a compact vertical column height.
Low Energy Thermal Footprint
Operates at ambient temperatures, eliminating heavy steam energy consumption required for distillation.
Automatic Phase Interface Control
Submerged interface sensors auto-regulate raffinate discharge valves to prevent phase entrainment.
Handles Heat-Sensitive Compounds
Preserves heat-vulnerable antibiotic APIs, vitamins, and delicate organic molecules.
- Recovery of Acetic Acid and Phenol from industrial wastewater streams.
- Extraction of antibiotics (Penicillin, Streptomycin) from fermentation broths.
- Separation of aromatics from aliphatic hydrocarbons in petrochemical refineries.
- Purification of rare earth metals and nuclear materials.
