The dioxide of sulfur in 2014 represented the second pollutant of more emission to the atmosphere for the fixed sources in Villa Clara, being the entities fuel oil consumers the responsible maxims. The objectives of this work have been to quantify the polluting load of the dioxide of sulfur emitted by the sources of the MINAG, to determine the percentage that represents these emissions of the total, for municipalities and consumption of fuel, to evaluate the quality of the air and to propose measures of reduction of the emission. The method applied was using direct mensuration with analyzers of gases and factors of emission of AP-42 of the Agency of Environmental Protection of the United States (EPA), the evaluation of the quality of the air was carried out through the moderation of the dispersion of the pollutant with the software ISC-AERMOD Version 3.15 of the EPA. The results show that the polluting load of the dioxide of sulfur was of 68 t, 80% emitted in the municipality of Santo Domingo and 97% to burn fuel oil. The quality of the air is acceptable, faulty and dreadful in near different areas to the emission sources. Applying the measures proposals, the energy efficiency can rise and to reduce the consumption of fuel to 3% (38 t) and the emission in 1.8 t, favoring the costs of the entities and propitiating smaller deterioration of the quality of the air in the affected areas.

Introduction: The emissions of pollutant gases into the atmosphere from steam generation systems are determined by the type and composition of the fuel. High sulfur fuel oil is responsible for sulfur dioxide emissions. It is necessary to know the impact on air quality of this pollutant from a stationary source, such as a recapping industry, in the sanitary hygienic radius. Objective: To quantify the sulfur dioxide generated in a tire recapping plant by means of emission and immission measurements in the hygienic-sanitary area of the same. Materials and Methods: A methodology was developed that includes the inventory of SO2 emissions as a function of fuel consumption for steam generation, dispersion modeling and immission assessment by low-cost sensor monitoring. Results and Discussion: The results evidence that SO2 in ambient air determined by emission modeling and monitored with low-cost sensors are similar and do not exceed the established limit value. Conclusions: The results of SO2 concentration evaluated with emission and immission measurements, show that it is the recapping industry the main source contributing to the air quality by the effect of this pollutant and in this study it is acceptable. In addition, the similarity of the immission values and the emission modeling justify the feasibility of using low-cost sensors to measure air quality. [ABSTRACT FROM AUTHOR]
