摘要：Magnesium production process is highly energy intensive. Electrolysis provides an effective route to reduce energy consumption and greenhouse gas emission for the magnesium production. This paper concerns the scale-up design of a 300kA magnesium electrolysis cell using a three-dimensional thermo-electric mathematical model. The model provides information on the steady-state thermoelectric fields thus allowing the evaluation of the effects of structure parameters (anode-cathode distance, anode thickness, cathode thickness, anode width, and anode number) on the current intensity, resistance voltage drop, and current density. Non-dimensional analyses give a linear relation between the current intensity and a set of dimensionless numbers, which upon further comprehensive analyses, gives a criterion for the scale-up. Such a scale-up criterion is found to be able to predict, within 1%, the amperage of 300kA magnesium electrolysis cells. The results suggest that the criterion could be used for the scale-up design of magnesium electrolysis cells with a high current intensity.
