QUANTIFICATION OF SULFUR DIOXIDE FROM AMBIENT AIR IN THE SANITARY PROTECTION ZONE OF A TIRE RECAPPING PLANT

Abstract

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.
