Mathematical Model of the Pressure Distribution and Consumption by Technological Lines of Uranium Hexafluoride Production
Savitskiy O.P. Dyadik V.F.

The article is devoted to one of the most urgent problems in the field of automation of technological processes of uranium hexafluoride production (PGFU) – to creation a mathematical model describing the hydrodynamic operation modes of production consists of two interdependent production lines. PGFU model is a set of mathematical models of individual process units and apparatus that have a significant influence on the processes in the technological scheme. The model is developed using mathematical descriptions of fundamental physical and chemical processes occurring in the apparatus on the basis of the material balance. Also took into account that during the passage of the gas through technological apparatus is changing its volume due to chemical reactions. The developed model is implemented in a software environment MATLAB & SIMULINK. Model coefficients are found as a result of data processing with the actual production. Adequacy of the model verification by comparing the values of the gas pressure at the output apparatus, measured on the actual production and calculated model. The created model allows the calculation of profiles of the gas flow and pressure on the two process lines PGFU taking into account their mutual influence.

Keywords: uranium hexafluoride production; technical fluorine; mathematical model; gas blower; flame reactor; coefficient of variation of flow.
