Regulatory pressure (e.g., REACH in Europe) is phasing out toxic solvents like hexane and chlorinated hydrocarbons. Alternatives include: solid-liquid extraction

Solid-liquid extraction, commonly known as , is a fundamental separation process. It involves removing a soluble solute from an insoluble solid matrix using a liquid solvent. This process is vital across multiple industries, ranging from metallurgical processing to food engineering and pharmaceuticals.

Low viscosity is required to facilitate rapid pore penetration and rapid mass transfer. It involves removing a soluble solute from an

The graph highlights the initial rapid washing phase, where surface-bound solute dissolves instantly. This is followed by the diffusion phase, where mass transfer rates drop as solvent penetrates deep into the remaining solid matrix. Advanced Extraction Technologies

High-frequency sound waves generate acoustic cavitation bubbles within the liquid solvent.
