The distillation column is a key piece of equipment for obtaining high-purity xenon (purity ≥99.9999%). This study is focused on analyzing the dynamic relationship between pressure and impurity concentration in order to construct predictive models, optimize the operational parameters of the column, and enhance the efficiency of separation. During the research, continuous monitoring of the column pressure and data collection on impurity concentration were conducted. To address data discontinuity, time intervals of less than 1200 minutes with more than three concentration measurement points were selected. Based on the filtered data, a segmented model describing two operating modes of the column was developed. For the dynamic pressure mode, a significant polynomial linear relationship was identified between the fluctuations in impurity concentration and the absolute value of the pressure change rate. During the stable pressure period, an exponential decay model was constructed to describe the dynamics of impurity concentration reduction. The model allows for predicting the time required to achieve the target impurity concentration and the degree of product purity within the expected stable operating time interval of the column. This contributes to optimizing the equipment’s operational parameters, reducing energy consumption, and improving the efficiency of gas mixture separation.
