The salt lake brines that lithium is extracted from have high chloride levels making the brine very corrosive to stainless steel extraction column internals. This is a significant problem in column scale-up to industrial production. Two types of corrosion-resistant ceramic internals, the hybrid ceramic internal and ceramic plate, were designed and tested under pilot conditions for future industrial application in this field. The hydrodynamic results (Yi et al. Ind Eng Chem Res 56(4):999–1007 (2016), [1]) show that holdup of hybrid ceramic internal is higher than that of ceramic plate by around 50%, while Sauter mean diameter when using the hybrid ceramic internal is smaller than when using t..
