2-m=6.5, the dependence of the velocity of the steam-gas mixture on the criterion
Depending on the speed of the steam-gas mixture, this velocity has a certain character.
Limitations on control parameters (T, m, W0) are set in industrial devices, we determine the effect of these limitations on the most favorable conditions.
In our case, since the rate increases with temperature, it is necessary to keep the temperature high. At the end of the cycle, the temperature will inevitably rise to -2300. It should be noted that the effect of the temperature limitation on the measured quantities is not very important.

Figure 8. Effect of velocity limitation of vapor-gas mixture on the optimal regime: Wo1, m1, Xk1, - with velocity limitation, Ԝ=10 mol/sec.m2
Wo2, m2, Xk2 - unlimited
The size of m and W0 parameters obtained with speed restrictions (W0≤Wonp) is larger than the size of parameters obtained without restrictions. Despite this, the difference in these measurements is not very significant.


CONCLUSIONS
A mathematical model of the process was obtained by changing the catalyst activity. The experimental parameters obtained in the experimental reactor are well described by the model.
The internal diameter of the tube was calculated under the condition of maximum permissible parametric sensitivity.
The approval process has been completed. The production yield of vinyl acetate was accepted as the acceptance criterion. The maximum principle is used to solve the problem. Optimum plots of temperature, molar excess of acetylene, and rate of reaction mixture with time were found. Optimal temperature profile along the length of the reactor is isothermal.
The analysis is carried out with the influence of the control parameters and the restrictions of the criterion types in the optimal regimes.
It was found that the long service life of the catalyst is 45 days.
