Environmental studies and projects

The atmospheric emission inventories are an important environmental management tool prepared to identify, characterize, and quantify the natural or anthropogenic sources of atmospheric pollutants in enterprises, cities, or regions.

The inventories prepared by EcoSoft highlight the most relevant sources, enabling the definition of strategies, actions, and goals for emission reductions, with a focus on improving air quality.

Emission inventories are also fundamental for the application of mathematical models of pollutant dispersion in the atmosphere, another EcoSoft specialty, which makes it possible to establish the relationships between cause and effect related to pollutant emissions and air quality.

Atmospheric pollutant dispersion models are powerful tools for assessing the impact on air quality caused by emissions of air pollutants.

We use a wide range of mathematical models of atmospheric dispersion, including:

– AERMOD (AERMIC Model)
– CMAQ (Community Multi-scale Air Quality Model)
– CALPUFF (California Puff Model)

We also use the WRF model (Weather Research and Forecasting Model) for weather forecasting and reanalysis of weather conditions. This type of modeling is widely used to produce data for application in atmospheric dispersion models.

EcoSoft has its own computer cluster dedicated to processing atmospheric models. It is capable of processing high resolution meshes and long periods of analysis.

Besides knowing the levels of air pollution in a region, it is often also important to know its composition.

The chemical characterization of particles makes it possible to detect the origin of pollutants present in a region, according to the analysis of tracer materials. This type of study is also known as Source Apportionment.

Based on the characterization of particles collected from emission sources and receivers of interest, we use the CMB (Chemical Mass Balance) model to establish the relationship between the probable sources and receivers. We use specialized equipment to collect these samples and we have the necessary experience for this task, and we also count on partner laboratories to determine the chemical and morphological characterization of the particles.

The CFD (Computational Fluid Dynamics) is the numerical simulation for solving the differential equations of fluid dynamics and heat transfer.

We make use of the most powerful CFD applications to better understand the atmospheric phenomena and add more background to the studies and projects developed by EcoSoft.

We combine these resources with the knowledge of our technical staff to achieve excellence in the environmental solutions we propose to our customers.

Air quality monitoring networks are systems capable of measuring concentrations of atmospheric pollutants and providing compliance with the objectives of the air quality monitoring plans:

– Check the degree of exposure of the population to atmospheric pollutants, considering public health criteria;
– Monitor medium and long-term trends to verify the effectiveness of control programs, assessing the need for improvements.

In order to achieve these objectives, air quality monitoring networks and monitoring plans must be properly designed.

At EcoSoft, the air quality monitoring networks consider the geographic and demographic characteristics of the region, the atmospheric emissions inventory and the conditions of dispersion of pollutants in the atmosphere.

EcoSoft is a pioneer in the application of optimization techniques for the projects of air quality monitoring networks, providing the best cost-benefit ratio, in addition to quality and representativeness of the data generated by the air quality monitoring systems.

We prepare plans for monitoring atmospheric emissions considering the specific characteristics of the project's emission sources, pollutants emitted, emission rates, and applicable requirements.
