This study proposes a dynamic mathematical model for simulating separation processes in distillation columnsunder transient operating conditions. Due to the high inertia and structural complexity of column contact devices,experimental analysis of dynamic behavior is often limited. To overcome this challenge, the separation column is modeledas a distributed system composed of lumped-parameter elements, including trays, reboilers, condensers, and refluxaccumulators. Each element is described using material and energy balance equations formulated as systems of ordinarydifferential equations.The model accounts for time-dependent variations in flow rates, component concentrations, temperature, pressure, andphase equilibrium during process disturbances. A set of simplifying assumptions is applied to reduce computationalcomplexity while preserving the essential physical characteristics of the separation process. Dynamic calculations areperformed discretely over time, enabling the analysis of transient responses caused by control actions.The model incorporates PID-based control strategies for key variables such as reboiler heat input, reflux rate, bottomproduct flow, and condenser cooling. The proposed approach can be effectively used for process optimization, controlsystem design, and the development of digital twins and operator training simulators for industrial separation columns
