| Summary: | The article deals with the dynamic optimization of complex
technological processes on the example of the process of
hydrotreating of diesel fuel. The purpose of the study is to create a
system of optimization of a group of technological installations in
real time. The relevance of the study is determined by the fact that
the existing optimal control systems solve the problem of local
optimization of one process, rather than the problem of global
optimization of oil refinery chains. There is also a problem of lack
of integration solutions between the optimal planning systems and
control systems of technological installations. As an integration
system, it is proposed to use the system of optimization of a group
of technological installations in accordance with the hierarchy
of refinery management systems, discussed in this article. In the
framework of the study, the identification of the technological
process to obtain a mathematical model of several plants of
different capacity using regression analysis methods of historical
data. The model has been evaluated with statistical estimates and
meets the requirements of accuracy and adequacy. As a result of
the study, a mathematical model of hydrotreatment is developed
to solve the problem of minimizing energy consumption while
respecting product quality restrictions. The quality of the obtained
model confirms that the creation of a system for optimization of
a group of technological units in real time is possible, and the
model can be used in dynamic optimization of the production
chain of diesel fuel. |
