Air Dispersion Modeling

Velosi’s Air Dispersion Modeling service provides high-precision simulations of pollutant behavior in the atmosphere to support environmental permitting and risk assessment. Designed for facilities emitting air pollutants, this service ensures compliance with EAD air quality guidelines, as well as international standards and best practices.

Our modeling covers a range of pollutants, including particulate matter, VOCs, SOx, NOx, and CO, and is applicable across various industries, from oil & gas and power generation to manufacturing and waste treatment. With a strategic approach, it aims to predict the transport, transformation, and deposition of pollutants in ambient air to ensure that emissions remain within regulatory limits and avoid adverse environmental and health impacts.

Velosi’s Air Dispersion Modeling uses advanced tools and deep regulatory expertise to help industries manage their emissions responsibly and timely.
