Development of Automation and Control System of Waste Gas Production Process Based on Information Technology

In the article, the thermal regimes of the layers of experimental solar pond with dimensions of 0.7 m and 1.5 m, height of 1.5 m, built in the training ground of Karshi Engineering Economics Institute, were mathematically modeled based on the climatic conditions of Karshi city. In the dynamic mode of the solar pond device, at a concentration of 25% of pond water, the energy collection efficiency of the layers was calculated analytically for the months of May, June, September and October, 2022. A mathematical model of the temperature changes of the layer over time during the absorption of solar radiation through the depth of the solar pond has been developed. The experimental and model calculation results of this solar pond were compared based on Fisher’s criterion. Among the monthly comparison results for each layer, the closest difference was observed in the LCZ layer, which was 8.8%.

The article presents research data on the process of adsorption refining (bleaching) of cottonseed oil, which differs from other vegetable oils in its complex composition and the presence of gossypol. Activated Tulsoh palygorskite has been proposed as a bleaching adsorbent. Studies have shown that the introduction of palygorskite in an amount of 1.0 to 2.5% helps reduce the color of both press oil and oils obtained by extraction.

In this article, in the process of deaeration of feed water in thermal deaerators in the saturation temperature range of 20-105 °C, a method is proposed for determining changes in partial pressure, absorption coefficient and concentration values of aggressive gases such as carbon dioxide, oxygen and nitrogen in the gas phase and dissolved in water is modeled according to Henry’s law, and the results obtained are graphically depicted; conclusions are given on how the correspondence of the saturation temperature to an increase in pressure affects the change in the concentration of aggressive gases.
