“…Influence of air on the temperature in the reactor and the flow rate of the final product 4-5. It can be seen from the table and figure that an increase in air flow reduces the temperature of the reactor, and also increases the flow rate of the final product to a certain value [12][13]. Influence of air flow on temperature and flow of sodium chloride.…”

The article presents a method for determining the optimal technological and design parameters of the process, as well as the procedure for conducting technological analysis in the Aspen Plus environment. With the help of a wide range of thermodynamic models and process property databases, this modeling environment allows for an accurate representation of their behavior in the production of nitric acid. By using computer modeling in Aspen Plus, a 60.09% aqueous solution of HNO3 was obtained for 93465.8 kg/h of air and 5458.9 kg/h of ammonia. The objective of this modeling was to determine the optimal process parameters and its configuration, conduct a technological analysis, and determine the flows and properties of substances at various points. The main process parameters were analyzed, and their interrelation is shown in the graphs.

“…Therefore, it is of interest to predict the expected tensile strains and to determine the beginning of element failure, i.e. -the beginning of cracking or delamination process at the contact of layers [15][16][17][18][19][20][21][22][23][24][25][26]. The ultimate stresses in the tensile region in the "Geomechanics" program are limited by the tensile strength limit, and they are automatically assumed to be equal to C/5 for elements that do not go into the plastic, and equal to zero for elements that go into the plastic at the previous iteration cycles.…”

The development of quarries and underground mines is characterized by the need to expand their borders and resume the work of temporarily non-working sections of the countries, as well as maintain the capacity for ore production, the reduction of which is associated with a reduction in the active area of ore bodies. At the same time, work intensification is necessary, which is complicated by the limited size of the working area. Such complications can be largely compensated for by increasing the height of the exploding sill. At the same time, work intensification is necessary, which is complicated by the limited size of the working area. Such complications can be largely compensated for by increasing the height of the exploding sill. This is precisely the purpose of the present research, which was carried out by processing arrays of information that allows us to optimize this process. The study was carried out with machine processing of the information and change of the studied parameters.

The article analyzes the developed non-linear predictive model of the control system in continuous time of the state space, including states, control and controlled values. The transformation of the continuous form of a function into a discrete one is carried out according to the trapezoid rule. Based on the discrete model, the optimality criterion for the objective function is formulated. The efficiency of the grinding process is considered based on the weight components of the model, since it entirely depends on the accuracy of estimating the particle size of the product and the performance of the plant. To control the volume of water in the sump, a dynamic inversion controller is provided, which makes it possible to reduce control problems to a solution in a closed form and guarantee asymptotic stability of the error dynamics.
