Magnesium Distillation for Impurity Separation

The patent divides the distillation process into two sequential stages: crude distillation for high-boiling-point impurities followed by rectification for low-boiling-point impurities. This segmentation allows each stage to be optimized independently, using a single integrated device rather than multiple complex separate systems, thereby maintaining impurity removal effectiveness while reducing overall device complexity.

The patent implements a continuous distillation process where magnesium and impurities are continuously fed into the crude distillation column, with the distillate continuously flowing into the rectification column. This continuous operation eliminates idle time between processing different impurity types, maintaining high productivity while using a streamlined single-device configuration rather than multiple batch-processing units.

The patent establishes a continuous flow system where crude magnesium and impurities are continuously processed through the crude distillation column, and the resulting distillate is immediately and continuously fed into the rectification column. This eliminates batch processing interruptions and maintains continuous purification action, significantly improving production efficiency while preserving the quality benefits of separate impurity removal through the sequential column design.

The patent merges the crude distillation and rectification processes into a single integrated continuous operation. Rather than operating separate batch distillation units sequentially, the system combines both purification functions in one continuous flow system, maintaining the quality advantages of differentiated impurity removal while achieving the productivity benefits of continuous processing.

The patent utilizes the thermal energy from the crude distillation process continuously by directly feeding the hot distillate into the rectification column without cooling or intermediate storage. This continuous thermal energy transfer eliminates the need to reheat materials between processing stages, significantly reducing energy consumption while maintaining the separation effectiveness achieved through the two-stage process.

The patent combines the crude distillation and rectification processes into an integrated energy-efficient system where the output of one stage becomes the immediate input of the next. By merging these processes and eliminating thermal cycles between stages, the system achieves effective separation of different impurity types while minimizing total energy consumption through continuous heat utilization.
