The process of multiple effect distillation for the recycling of magnesium can both increase efficiency and reduce cost by up to 90% when compared to batch distillation refinement. This paper will detail the design and experimentation of a novel continuous gravity-driven multiple effect thermal system (G-METS) distillation process for magnesium alloys. Single-effect batch distiller experiments examine the evaporation kinetics of Mg alloys while confirming aerosol separation techniques. Further experiments using a two-effect, and later three-effect, continuous G-METS distiller seek to validate model predictions and magnesium recovery rates. Magnesium alloy recycling via distillation presents unique challenges that require various design considerations, such as temperature differentials and counter-flow processes for volatile element separation. The described application of G-METS for recycling offers an opportunity for low-cost recovery of pure magnesium from multiple types of magnesium-based alloys.
