Desagregación Espacial y Temporal del Inventario de Emisiones por fuentes Fijas de la ciudad de Villavicencio-Meta

Abstract

The accelerated growth of the populations of the industry affects in a direct way the quality of the air in the cities, this represents a problematic that day to day takes more importance in the social and environmental scope, because they generate problems as affectation to the health of the people to the deterioration of the ozone layer and the increase of the temperature of the planet, The increase in emissions in large cities represents a great challenge for industries, since these emissions are the cause of respiratory and cardiovascular diseases, associated with the pollutant criteria worked on in this project. As a model for future studies, this proposal was proposed in order to establish the state of air quality in the city, its schedules and the most critical points of concentration of pollutant criteria. For this purpose, a preliminary investigation was carried out based on secondary information provided by the Cormacarena Corporation, which was asked to list the companies that had valid emissions permits. This is due to the fact that these companies periodically report their emissions to the corporation based on the isokinetic monitoring of all their fixed sources present there, after this, the data obtained as: concentration of pollutants criterion, raw material consumed in the process, volumes of fuel used and type of raw material, were fundamental for the development of the emissions inventory and thus to be able to find by means of the emission factors the concentration of pollutants criterion in Tons/Year for each company, subsequent to this the emission data found served as input data to make the spatial and temporal disaggregation, which is a fundamental part of this project because that is where it was possible to evidence the areas of the city that are most affected by the daily work of the companies object of this study. In the case of dispersed fixed sources, we worked with the service stations in the city based on the list of service stations in the country supplied by the (Ministry of Mines and Energy) which showed a total of thirty-four service stations operating normally in the city, At the same time, it was possible to identify the behavior of the pollutants, criteria both in scattered fixed sources and point sources, showing a similar behavior in the maps obtained.
