“…The SIMPLE numerical algorithm (semi-explicit method for pressure related equations) by Patankar and Spalding (Patankar, 1980) was used to numerical solve the equations system (1)-(4). The use of this numerical algorithm is described in detail (Issakhov & Baitureyeva, 2019;Issakhov & Mashenkova, 2019;Issakhov & Zhandaulet, 2019;Issakhov et al, 2019a;Muhammad et al, 2020).…”

In this work, a computational simulation of the pollutants spread generated during fuel combustion at Ekibastuz SDPP-1 and their chemical reaction in the atmosphere have been presented. Using the example of a real thermal power plant (Ekibastuz SDPP-1), the dispersion NO, NO 2 , CO and products NO 2 , HNO 3 , CO 2 during a chemical reaction with oxygen was modeled. The numerical method was verified by solving three test problems and the received computational solutions were compared with data from the measurement and the computational data of other authors. The purpose of the work was to investigate the pollution level at various ranges from the source. As a result, the mass fraction of the concentration and product during a chemical reaction were determined. According to the obtained data, with increasing distance from the source, the concentration of pollution spreads more widely under the influence of diffusion. The farther the distance from the chimney, the lower the concentration of the substance and products. Thus, the obtained computational values may allow in the future predicting the optimal distance from residential areas for the construction of thermal power plants, at which the concentration of emissions will remain at a safe level.

“…In another study, Issakhov and Baitureyeva developed a 2D and 3D CFD model to numerically investigate the rising pollution from thermal power plants. In addition, they calculated the pollution concentration level at various distances from the emission source [24]. Furthermore, some scholars have focused their attention on the reactive dispersion of VOCs and NOx as the primary pollutants that lead to the production of secondary pollutants.…”

BTEX species are abundant volatile organic compounds that are classified as main pollutants by several environmental protection agencies. In this study, a new 3D air pollution dispersion model with the capability of taking into account the BTEX's reactions was developed and evaluated. The Toxchem model is employed to estimate the amount of emitted BTEX from several area sources, followed by simulating the transport of the reactive species through a 3D model. Also, reduced mechanisms were developed, based on Master Chemical Mechanism (MCM), for the simulation of the atmospheric chemistry of BTEX. The application of the mechanism reduction method yielded a mechanism of 43 species and 45 reactions. Based on findings, the deviation of the reduced mechanism from the whole mechanism was < 4% throughout the simulation. In addition, the result showed that, during a 12 h period of simulation, the effect of the atmospheric chemical reaction on reducing the final concentration of benzene, toluene, ethylbenzene, m-xylene, o-xylene, and p-xylene was about 0.3, 1, 1.4, 5, 3.1, and 3.2%, respectively. Lastly, it was indicated that the estimated emission rates by Toxchem and simulated concentrations by the dispersion model were in good agreement with the reported experimental values.
