Resumen
El aporte de las emisiones industriales a la contaminación del aire de Bogotá es significativo y, dentro de las industrias, aquellas que usan carbón como fuente de combustible para la generación de vapor en calderas son las que mayor impacto negativo tiene en la calidad del aire de la ciudad. En este trabajo se llevó a cabo la evaluación de las variables de operación de un sistema de control de emisiones atmosféricas para una caldera industrial a carbón. Se diseño, construyó y puso en marcha un lavador de gases tipo venturi. Se evaluó la remoción de material particulado (MP) y dióxido de azufre (SO2) a diferentes condiciones de operación, basados en un diseño experimental tipo factorial. Se definieron como variables la forma de inyección de la solución de lavado, el flujo de gas y el flujo de líquido. Adicionalmente, se evaluó el comportamiento de la caída de presión en el venturi y la variación de la temperatura de los gases de combustión. Finalmente, se determinaron las condiciones de trabajo más favorables para la caldera y el sistema de control y se determinó la concentración de los contaminantes de interés para comparar los resultados obtenidos contra los valores máximos permisibles establecidos por la normatividad nacional para este tipo de fuente fija.
Abstract. The contribution of industrial emissions to air pollution in Bogotá is significant and, among industries, those that use coal as a fuel source for the generation of steam have the greatest negative impact on air quality in the city. In this work, the assessment of the operating variables of a control system for air pollutants from a coal-fired industrial boiler was carried out. A venturi scrubber was designed, built, installed and evaluated. Following a factorial experimental design, the removal of particulate matter (PM) and sulfur dioxide (SO2) was evaluated at different operating conditions. The way of injecting the washing solution, the gas and liquid flows were defined as main assessment variables. In addition, the pressure drop across the venturi and the variation of the temperature of the combustion gases were monitored. Finally, the most favorable working conditions for the boiler and the emission control system were identified and the concentrations of pollutants of interest were determined to compare the results against the maximum permissible values established by national regulations for this type of stationary source.
