Kravchenko Y. Computer-integrated technology for secondary condensation of ammonia production under uncertainty

Computer-integrated technology is the control of technological processes or organizational and technical complexes using computer and microprocessor technology. As a rule, computer-integrated technology is used for complex technological systems, which is the production of ammonia in general and, in particular, secondary condensation. The object of research is the process of control of heat exchange and hydromechanical systems for the extraction of production ammonia, which occur in the technological complex of secondary condensation of synthesis units. The subject of research is the computer-integrated technology of the secondary condensation complex under conditions of uncertainty, in particular, mathematical models, methods and identification algorithms, software control systems for the technological complex. In the thesis, the scientific and practical problem of increasing the economic efficiency of ammonia production by creating an optimal structure and a computer-integrated program control system for a secondary condensation complex, taking into account its behavior, which functions under uncertainty, has been solved. The solution is implemented using the modern provisions of the systems approach, probability theory, multivariate statistical analysis, identification theory, mathematical modeling and automated control. The introduction substantiates the relevance of the research tasks, shows the relationship of work with scientific programs, plans, themes, provides scientific novelty and formulates the practical significance of the results.
