Spatial-Temporal Estimation And Disaggregation Of Criteria Pollutants And Black Carbon Emissions From Stationary Industrial Sources In Bogotá

Estimation and time-space disaggregation of stationary industrial sources methodology has recently been improved through the different tools available at the Bogotá Environment Secretariat (SDA). Based on 2018 database, the distribution of fuel use in stationary industrial sources was natural gas (87% of stationary sources), followed by coal (4%), diesel (3%) and other fuels (6%). Fuel consumption and emission factors were taken to SDA 2018 database; emission control systems efficiency was included based on qualitative and quantitative criteria and the operating hour of these sources were considered for reconstruct the hourly emissions profiles for three standard days (weekdays, Saturdays, and Sundays). Finally, with the location of each of the sources, the emissions can be spatially added in a 1kmx1km mesh. In this study, the estimated total emissions for stationary industrial sources were: 2.74E+02 t/y PM10, 8.43E+01 t/y PM2.5, 7.46E+02 t/y NOX, 6.22E+02 t/y SO2, 2.72E+02 t/y CO, 2.98E+01 t/y COV and 7.43E-03 t/y BC.
