Studies and Projects

EcoSoft develops a wide range of services related to the environment in general, with emphasis on the management of air emissions, air quality and meteorology.

Prognostic and diagnosis on the air quality impact assessment
Developed based on globally recognized protocols and aided by last generation meteorological and atmospheric dispersion models, such studies identify the impacts of air pollutant emission sources on the air quality of direct influenced area, for the present moment, past or future.

Air quality studies are essential and mandatory part of the Environmental Impact Assessment for companies with significant emission of air pollutants. These studies also can assist for choosing the most effective environmental control systems as well for design of the air quality monitoring networks.

Modeling of pollutant dispersion in the atmosphere
It is a powerful tool used in environmental management, that allows the assessment of the impact on air quality caused by emissions of air pollutants from one or multiple sources, also considering the meteorological conditions and the surface characteristics of modeled area.

We use a state of art mathematical models, approved by internationally accredited environmental agencies such as the CMAQ model (Community Multi-scale Air Quality Model), CALPUFF, AERMOD, among others.

EcoSoft has 20 years of experience in the use of atmospheric dispersion models, having performed more than 300 modeling works. We have our own computer cluster with high processing capacity and skilled professionals for the implementation and interpretation of results.

Inventory of air pollutants emission sources.
The identification, characterization and quantification of air pollutant emissions in an enterprise or across a metropolitan area are carried out according to international protocols, with data quality control.

Inventories may include stationary and mobile, point and diffuse sources, considering all relevant pollutants or characteristic of the company and the region, such as particulate matter (TSP, PM10, PM2,5), sulfur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, hydrocarbons, odorous gases, fluorides, heavy metals and others.

Emissions from marine aerosols, atmospheric discharges, biogenic emissions, wind erosion of soil particles and surfaces, forest burning, among others can also be inventoried. EcoSoft also has extensive experience in air emissions inventories in oil extraction, refineries, steel, mining, pulp and paper, chemical, power generation, transportation (trains, ships, trucks and off-road machinery), as well as inventories of urban emissions, such as vehicle, evaporative, household and commercial emissions, among others.

Air quality and meteorology assessment
Made from monitoring data provided by the client or generated by EcoSoft, providing the diagnosis of air pollutants from one area of interest.

EcoSoft owns next-generation mobile automatic monitoring stations that enable a continuous measurement of air pollution levels and weather conditions, using methods and equipment approved by the USEPA. The stations are leased by the required time (minimum of 30 consecutive days), and EcoSoft provides the transportation, installation, operation, maintenance and uninstallation of the station, giving the customer the detailed report of measurements with the interpretation and analysis of the generated data.

Assessment of airshed capacity
Verifying the current state of saturation compared to the existing standards, through data readily available or collected in specific monitoring campaigns.

To the current situation are added the increments of pollutant concentrations due to the implementation of planned projects calculated by mathematical modeling, verifying the sustainable maintenance of air quality across the region of interest and the compliance with the air quality standards.

Design of optimized networks for air quality monitoring and meteorology
The monitoring network design takes into account the geographical characteristics of the region, the inventory of pollution sources stations and pollutant dispersion conditions in the atmosphere, providing cost-effective, and high fidelity generated data.

The optimization techniques employed in the designs allow the maximization of network coverage measurement area and minimize the number of stations and sensors used, given a specified coverage efficiency.

EcoSoft has designed more than 40 optimized air quality monitoring networks in Brazil, Africa and Asia, including big metropolitan areas like Belo Horizonte, Rio de Janeiro, Vitória, São Luís, among others.

Efficiency assessment and bearing capacity of installed control systems
Particularly useful when expanding the production capacity of an enterprise, when you must ensure that the control system already supports increasing the desired output without risks on air quality or violate established emission limits.

It is the analysis of the operating conditions of a specific production process and its control systems pollutant emissions, verifying the safety limits for its operation.

If necessary and viable, solutions to extend the pollutant retention capacity of the installed control system and / or required additional control measures are indicated.

Mesoescale meteorological modeling
EcoSoft uses state of the art meteorological models (such as the Weather Research and Forecasting Model-WRF) for processing meteorological scenarios of high spatial resolution for weather forecasting and reanalysis of weather conditions that occurred in any part of the planet in the last 10 years.

Besides the weather forecasting, this type of modeling is widely used for the production of data to be used in analytical and numerical models of atmospheric dispersion, such as AERMOD, CALPUFF and CMAQ.

Environmental licensing
Licensing and environmental regulation of small, medium and large enterprises, also in partnership with several renowned companies in Brazil.

Design of water, soil and air pollution control systems.
EcoSoft has a specialized staff with 20 years of experience in the development of pollutant emission control systems design and / or installation of improvements in the production process, helping our customers in the adoption of sustainable solutions for their productive activities.

Development of improvement actions plans
Recommended when a process or project needs to reduce its emissions of air pollutants to meet the emission standards or air quality standards in its surroundings.

Inventory of greenhouse gases (GHGs or GHG)
Produced according to internationally recognized criteria and methodologies recommended by the IPCC (Intergovernmental Panel on Climate Change) – Guideline 2006 IFC (International Finance Corporation), International Organization Standardization (ISO), GHG Protocol – World Resources Institute (WRI) and the Brazilian Program GHG Protocol.

Inventories include direct (Scope 1) and indirect (Scope 2 and 3) emissions, allowing the identification and qualitative characterization of the nature of Greenhouse Gases (GHG) attributable to the enterprise complex inventory, including GHGs covered by the Kyoto Protocol :

(i) carbon dioxide,
(ii) methane,
(iii) nitrous oxide,
(iv) hydrofluorocarbon,
(v) perfluorocarbons,
(vi) Sulphur hexafluoride.

Chimney projects
Aims to minimize the environmental impacts caused by the emission of gases and particles in the atmosphere of its directly influenced area.

Well-designed fireplaces can substantially reduce the impact of emissions on air quality in their surroundings, being an important asset to be considered on developments with several chimneys and significant emissions.
