Principles and Process of Air Dispersion Modeling
Air dispersion modeling uses emission data, meteorological conditions, and site characteristics to simulate how pollutants spread from industrial sources.
These models provide a detailed quantitative picture of pollutant concentrations, help identify sensitive receptors, and assess the potential impacts of different emission scenarios.
Modeling is required by environmental authorities as part of emission permit applications, environmental impact assessments, and emission-reduction planning.
Key Advantages of Air Dispersion Modeling
- Accurate Assessment – Precise estimation of pollutant concentrations around industrial facilities
- Informed Planning – Supports effective air quality management and emission-reduction strategies
- Regulatory Compliance – Ensures adherence to environmental standards and prevents penalties
- Operational Optimization – Identifies opportunities for improving process efficiency
- Future Planning – Enables prediction of environmental impacts for facility expansions or process changes
