عنوان انگلیسی Assessing CO2 Emission Dynamics and Dispersion Patterns from Turbines in a Petrochemical Facility in Southwest Iran
چکیده انگلیسی مقاله Background & Aims: The emission of greenhouse gases presents a daunting challenge in today's world. Among these gases, carbon dioxide (CO2) stands out as the most significant, affecting the environment on regional, global, and local scales by contributing to some phenomena, such as the heat island effect. The present study aimed to assess the emission rate and model the dispersion of CO2 from the chimneys of turbines in a petrochemical complex located in southwest Iran in 2023.
Materials and Methods: In this descriptive-analytical study, we first calculated the CO2 emission factor using the DCCEE 2009 method. We then estimated its dispersion model based on the Domino and Gaussian methods. In addition, field measurements of CO2 concentrations were conducted to validate the accuracy of these models.
Results: The results indicated that the average Global Warming Potential (GWP) attributable to CO2 emissions from turbine chimneys in the petrochemical complex is approximately 10,718.85 tons of CO2 equivalents per month. Dispersion modeling using the Domino method revealed a rapid decrease in CO2 concentrations with increasing distance from the emission source, with levels dropping from 1000 ppm at the emission point to 60.65 ppm at 100 meters away, illustrating the effectiveness of distance in mitigating exposure. The Gaussian method results pointed out that CO2 concentrations increase under conditions of greater atmospheric instability from more than 1000 ppm decreases to 1.1 ppm, suggesting an interaction between environmental factors and pollutant dispersion. A comparative accuracy assessment demonstrated that the Gaussian model provided a more reliable estimation of CO2 concentrations at varying distances from the chimneys, yielding R² values of 0.9962 and 0.9728 for the Gaussian and Domino methods, respectively.
Conclusion: The findings of this study highlight the substantial contribution of turbine chimneys in the petrochemical complex to greenhouse gas emissions, particularly CO2, posing significant environmental challenges.
