Concentration Distribution of Molecules and Other Species in the Model System Fe-NaCl-Na2S-H2SO4-H2O at Various Temperatures of the Electrocoagulation Process

Zarlık MAYMEKOV | Canarbek İZAKOV | Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Mehmet KOBYA

Under practical conditions, one of the possible solutions to the problem of treatment of hydrogen-sulfide-containing industrial wastewater is the electrochemical oxidation of sulfides. In this work, the model system Fe-NaCl-Na2S-H2SO4-H2O is considered, an experimental setup is constructed, and the electrocoagulation process is studied in a wide (288-308 K) range of temperatures of an aqueous solution of hydrogen sulfide. The optimal ratios between the initial components in the system are determined. The experimental and calculated pH of the solution are found. The system is thermodynamically ...Более

Possibilities for Prediction And Evaluation of the Carbon Footprint in Furnace Fuel Oil Combustion in Medium- and Low-Power Boilers

Mirlan MOLDOBAYEV | Zarlık MAYMEKOV

To predict and evaluate the carbon footprint in the gas phase, furnace fuel oil oxidation in excess air (alpha factor 1.3) was studied over a wide temperature (T 298–3000 K, P 0.1 MPa). Equilibrium thermodynamic parameters (entropy, enthalpy, and internal energy) and the concentration distributions of C-, S-, N-, O-, and H-containing components and active particles in the gas phase were determined. Based on the total concentration distribution of C-, S-, N-, O-, and H-containing components and active particles in the gas phase, the weight content of carbon was calculated. Taking into account t ...Более

Electrochemical Sulfur Removal at Controlled and Uncontrolled pHs with an Iron Anode

Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Zarlık MAYMEKOV | Mehmet KOBYA

In this study, sulfide removal was carried out in the Electrocoagulation process under controlled and uncontrolled pH conditions. Under optimum conditions, electrocoagulation took place in less than 40 minutes at uncontrolled pH and less than 30 minutes at controlled pH to reduce the sulfite concentration of the effluent below 0.5 mg/L. The reaction rate constant and iron-sulfide molar ratio for sulfide removal were 14.09 x 10(-2) min(-1) and 0.97 mol/mol, respectively; under uncontrolled pH conditions, they were 22.88 x 10(-2) and 0.97 mol/mol at controlled pH. The mg sulfide removed per g Fe ...Более

The Impact of Road Salts on Groundwater and Estimation of the Chlorine Ions by Hydrogen Index

Canarbek İZAKOV | Kubat KEMELOV | Nurzat ŞAYKİYEVA | Zarlık MAYMEKOV

In this study, the influence of road salts on groundwater was investigated. The use of anti-ice reagents in winter requires certain precautions since the main chemical composition of the salts is chlorides. At the same time, the widely used sodium chloride does not form ion pairs in water, which means that it has a high migration ability and a weak sorption potential. In addition, the concentration of chloride salts in the components of the environment is so high (10-140 ppm). Therefore, the rapid assessment of the concentration of technogenic chlorine ion in water by pH is an urgent task. The ...Более

Reducing Concentrations of Benzo(a)pyrene in Gas Phase Soot Particles by Using and Burning Water Fuel Emulsions

Kubat KEMELOV | Zarlık MAYMEKOV

In this study, benzo(a)pyrene-water-oxygen systems were investigated in wide ranges of change of temperature value and initial components to predict in which conditions benzo(a)pyrene degraded into more harmful substances. Consequently, the thermodynamic parameters of the benzo(a)pyrene-water-oxygen system were calculated and the concentration distribution of carbon, hydrogen and oxygen-containing particles in the gas phase were established. Adding water into the system allowed decreasing of carbon and acetylene. These elements are the key elements of benzo(a)pyrene formation. According to thi ...Более
