Abstract This paper establishes a PRO/II dynamic simulation model for the propylene distillation column based on actual operational data. It conducts a sensitivity analysis of single operational parameters and combinations of operational parameters, including operating pressure, feed temperature, and reflux ratio, to identify the key operational parameters affecting the yield and thermal energy consumption of the propylene column. A regression analysis method was employed to model the energy consumption of the column, and the significance tests of the regression equations confirm that the developed energy consumption model was accurate and reliable. This research lays a new theoretical foundation for the multi-objective energy-saving optimization of the propylene distillation column.
