Lithium extraction from salt lake brine with high Chloride levels is very corrosive and requires a large number of stages. Two types of novel anti-corrosive ceramic internals, the hybrid ceramic internal and ceramic pulsed plate internals have been tested under pilot conditions for future industrial application in this field, along with CFD models that have been developed for these two columns. Both CFD and pilot tests show that holdup of the hybrid ceramic internal is higher than that of ceramic plate by around 50%, while Sauter mean diameter of hybrid ceramic internal is smaller than that of ceramic plate by around 30%. Axial dispersion and mass transfer parameters are also presented and the results show that the hybrid ceramic internal has 50% lower axial dispersion coefficient and 50% higher mass transfer coefficient, contributing to higher mass transfer efficiency making it promising for application in the near future.
