Development of a Mathematical Model and Solution to the Problem of Optimizing the Vacuum Block of Oil Distillation Unit

As it is known, one of the initial and important stages in the creation of optimal control systems ofoil refining technological units is the development of a mathematical model that can adequately record theprocesses at any time. Studies have shown that the lack of information about the state of complex oilrefining processes in many cases reduces their efficiency and effectiveness. On the other hand, the widerange of both quality and quantity of raw materials for processing makes their efficiency even moreunsatisfactory. Under these conditions, it is difficult to develop mathematical models that can adequatelydescribe the static modes of technological processes. Due to this the development of mathematical modelsis relevant both in scientific and practical terms. Taking into account the above, in the presented paper isdeveloped a deterministic mathematical model that can adequately reflect the current technologicaloperating conditions of a vacuum unit, which is the main device of the vacuum column of the primary oilrefining technological complex. On the basis of this model, an optimization algorithm is developed thatallows to calculate the optimal operating modes of the vacuum block.
