Abstract Scope |
Gravity-driven multiple-effect thermal system (G-METS) is a new method for potentially reducing both the cost and energy use of industrial magnesium distillation by as much as 90%. It uses gravity pressure head in standpipes to create pressure differences between effects, creating a cascade of multiple evaporations using heat of condensation. This talk will describe a detailed mathematical model of G-METS magnesium distillation including kinetics of alloy evaporation. Aspects of the model describe counter-flow evaporators and condensers which can separate volatile alloying elements such as zinc. Validating experiments include one- and two-effect batch distillation of Mg alloys including Zn, Al, Mn, Fe, Ni and Cu. Finally, a new primary production flowsheet using G-METS distillation can potentially reduce the cost of magnesium below that of aluminum. And this can in turn potentially enable new uses of magnesium for grid energy storage and transportation. |
