As the object of control, the process of oil distillation in the atmospheric column is complex and multidimensional with interconnected controlled variables. These controlled variables are the outgoing indexes of the column – the quality of receivable hydrocarbon fractions, for assessment of which the boiling point for each product is used. The basic perturbation actions to the process are connected with the adjustment of quantity and the composition of feed stock supplied to the column and flow heat transfer change due to temperature fluctuation of feed stock, temperature fluctuations of external reflux and other factors.
