Integrated distillation systems reduce the energy consumption of industrial processes, so the use of integrated units in modern large-scale refineries is a matter of current interest. On the other hand, thermal and mechanical integration along with the complexity of multicomponent mixtures cause simulation and control difficulties. The objective of the research is to study energy efficiency and parametric sensitivity of the fully integrated crude fractionation unit (FI CFU, Petlyuk column). This type of column was designed to maximize diesel recovery and ensure that the fraction recovered meets the key specifications for diesel. We also selected the most suitable control parameters and specified the reflux rate areas of potential unstable operation.
