Dispersión de contaminantes atmosféricos por fuentes fijas de combustión del Parque Industrial de la ciudad de Cuenca, mediante los software Screen view 3 y Disper 5.2

Abstract

The air contamination is a global problem. In the city of Cuenca we find two important sources of contamination: The vehicle fleet and the industrial park. This investigation reveals the dispersion of pollutants (CO, NOx and SO2) in the city which originate from the industrial sector. For this we elaborated an inventory of realized emissions through bibliographical review and on-site survey applying the methodology established in TULSMA and in the Ministerial Agreement 097-A. A total of 122 industries were examined and 22 of those are considered fixed sources of emissions.

It found that the major contaminant was SO2 with 69,5437 g/s, followed by NOx with 19,6781 g/s and finally CO with 2,9226 g/s.The major contributors in the category of production of carton and paper are SO2 and NOx and CO in the category of the industrial pharmaceuticals and chemical products. It presented the modeling of the dispersion of the contaminants (CO,NOx,SO2) utilizing the software Disper 5.2 and Screen View 3 and finally we proceeded to compare those two softwares on a qualitative scale where we took into account 5 aspects: easiness of comprehension, graphic quality, portability, security and accuracy of information. Disper 5.2 achieved an evaluation of 4 which is acceptable and Screen View 3 with an evaluation of 3,6 belongs to the rank of accepatble.
