Water is an effective additive to fuel oil to reduce the concentration of soot in the gas phase

Mirlan MOLDOBAYEV | Kubat KEMELOV | Zarlık MAYMEKOV

Soot is one of the products of incomplete combustion of hydrocarbon fuels. It has the property of adsorption of active and carcinogenic substances on the surface of soot particles. In this regard, in burner equipment of medium and small power, it is required to develop and implement effective environmental measures to reduce emissions of soot particles. In this paper, the fuel oil-water-air system at a wide temperature range (T500-3000K) was studied and the ratio of gas-liquid flows (water content in fuel oil 5-15) at the maximum entropy of the system and the formation of soot in flue gases wa ...More

Prediction of the formation of low-molecular components, particles, and condensed phases during thermal destruction of oil-contaminated soil

Kubat KEMELOV | Zarlık MAYMEKOV

In this study, thermodynamic modelling of the process of thermal destruction of oil-contaminated soil of Ozenmunaigas JSC, which includes compounds such as carbon, silicon, aluminum, iron, calcium, magnesium, sodium, potassium, chromium, phosphorus, manganese, copper, titanium, molybdenum, nickel, vanadium, and water, was carried out. The physicochemical and thermodynamic parameters of the complex system were calculated at P0.1 MPa, T598-3000 K. The concentration distribution of components, particles, and condensed phases in the gas phase has been established. In the process of thermal destruc ...More

Study on antimony cake as a technogenic raw material for the production of antimony oxides

Zarlık MAYMEKOV

In the process of hydrometallurgical and pyrometallurgical production of antimony at the Kadamzhai antimony plant of the Kyrgyz Republic, large-tonnage waste was generated: tailing sand, matte, slag, off-balance ore, cakes, furnace fragments, and electrolytes in salt warehouses. The waste cake is poorly studied; accordingly, the elemental and phase compositions of antimony cake have not been established. In this regard, it was noted that antimony in the cake occurs in the form of calcium antimonate and antimony hydroxide. The content of antimony in the mine tailings cakes is from 3.53 to 4.4%, ...More

The concentration distribution of components and particles in the system: tomato-water-sodium nitrate and assessment of the oxidation-reduction potential at different temperatures

Nurzat ŞAYKİYEVA | Canarbek İZAKOV | Zarlık MAYMEKOV

The paper considers a triple complex system of tomato, water and sodium nitrate. Taking into account the average macronutrient composition and moisture content of field and greenhouse tomatoes, physicochemical modeling of the system was carried out tomato-water-sodium nitrate. The hydrogen index of tomato was determined at various temperatures and it was noted that tomato medium was acidic. It is shown that with an increase in the content of sodium nitrate in the system: tomato - water - sodium nitrate within the temperature range from 278 to 293 K, the hydrogen index of tomato increases, i.e. ...More
