Modular intensified liquid-liquid extraction for organic acid recovery
Modular, Multiphase Separation and Extraction (MPSE) technology intensifies liquid-liquid extraction for efficient organic acid recovery. Using a microscale-based architecture and capillary pressure gradients, it enables faster processing, improved energy efficiency, and rapid phase separation. The modular design supports scalability via additive manufacturing and can be tuned for different solvents and application-specific properties.
Overview
The Modular, Multiphase Separation and Extraction (MPSE) technology enhances the efficiency of liquid-liquid extraction processes for recovery and purification of small organic acids. MPSE uses a microscale-based architecture to intensify mass transport and enable rapid phase separation. By leveraging capillary pressure gradients together with its internal architecture, MPSE targets improvements in process speed, energy efficiency, and scalability, making it suitable for industrial organic acid recovery and purification.
