A New Phase Dispersion and Superior Phase Separation System

摘要

New dispersion/separation system improves both the mass transfer of metals in hydrometallurgical extraction applications and improves phase separation using a new concept in liquid-liquid centrifuges. The new dispersion device is able to disperse one phase into a second phase independent of flow ratio. This new patented dispersion and mixing device creates distinct and uniform droplet sizes. Producing distinct and uniform droplet sizes allows for optimization of mass transfer and phase separation. A unique patented manufacturing process results in substantially lower cost for the centrifuge separator, producing an economically viable alternative to current phase separation systems. Mass transfer, higher stage efficiencies, low hold-up, low residence time, low diluent inventory and usage, lower separator cost and high turn down ratio are several advantages the overall system application has over existing SX process equipment. The overall system is completely closed reducing air entrainment. Reduced air entrainment lowers reagent degradation and enhances phase separation. Additionally, the closed system reduces VOC emissions (air pollution) ad lessens organic loss. This new system delivers market changing improvements in comparison to existing centrifugal extraction systems.
