Liquid-Liquid Extraction System

Products > Chemical Processing Systems > Liquid Liquid Extraction System

A liquid-liquid extraction system is a sophisticated separation technology that isolates or removes specific compounds from a liquid mixture by contacting the mixture with an immiscible extraction solvent. The process relies on the differential solubility of the target component between two immiscible liquid phases, enabling selective mass transfer without thermal separation.

Our liquid-liquid extraction equipment is engineered for applications where distillation is impractical, such as separating heat-sensitive compounds, handling azeotropic mixtures, or processing components with close boiling points. The system operates on principles of thermodynamics, hydrodynamics, and mass transfer to achieve refined separation with minimal energy consumption. Unlike energy-intensive distillation, our chemical extraction system offers gentle processing that preserves thermally sensitive components while delivering high-purity extracts. Available for both batch and continuous operations, our systems are designed for pharmaceutical purification, chemical processing, metal recovery, and solvent recycling applications.

Our liquid-liquid extraction equipment is engineered for superior mass transfer, operational flexibility, and process efficiency.
Each feature addresses specific separation challenges across diverse industries.

What is a liquid-liquid extraction system?

A liquid-liquid extraction system is a separation technology that transfers a target compound from one immiscible liquid phase to another based on differential solubility. It is used to purify, concentrate, or remove specific components from liquid mixtures without thermal separation.

How does solvent extraction work?

Solvent extraction works by intimately contacting two immiscible liquids (the feed and the solvent). The target compound partitions between phases according to its distribution coefficient, transferring from the feed phase to the solvent phase. The phases are then separated, yielding an extract (solvent with target) and raffinate (depleted feed).

What industries use liquid extraction equipment?

Key industries include pharmaceuticals (API purification), chemicals (product separation), hydrometallurgy (metal recovery), petrochemicals (aromatic extraction), food processing (oil refining), and environmental engineering (wastewater treatment).

What solvents are used in extraction processes?

Common solvents include organic compounds such as kerosene, toluene, methyl isobutyl ketone (MIBK), ethyl acetate, and dichloromethane, as well as specialized extractants such as D2EHPA, Cyanex, and Alamine for metal extraction. Solvent selection depends on target compound solubility and process compatibility.

Can extraction systems be customized for specific chemicals?

Yes. As an experienced liquid-liquid extraction equipment manufacturer, we provide fully customized systems based on your specific feed composition, target compound, solvent system, flow rates, and purity requirements, from laboratory units to full-scale industrial plants.
