Abstract Scope Multiple effect distillation of magnesium has the potential to dramatically reduce the energy consumption and cost of magnesium refining compared to conventional batch distillation procedures. This method can be used for many applications, including primary production and recycling of magnesium, and extraction of rare earth metals from magnets. This study is developing a microscopic model for a novel continuous gravity-driven multiple effect thermal system (G-METS) approach for magnesium distillation. Modeling is presented as a design tool for determining the effect of geometric parameters such as feature size, and operating parameters such as temperatures, on separation performance and energy consumption of distillation. The present work used the COMSOL Finite Element Analysis software to analyze fluid flow and heat and mass transfer in the system. The model includes both liquid and vapor flow, and illustrates the effect of novel design features which promote counter-flow evaporation on volatile element separation.
