HOYOS BARRETO, Andrés Emilio; JIMENEZ CORREA, Mónica María; ORTIZ MUNOZ, Alejandro and MONTES DE CORREA, Consuelo. Cement plant gaseous pollutant emission reduction technologies. Ing. Investig. [online]. 2008, vol.28, n.3, pp. 41-46. ISSN 0120-5609.
A brief description of SOX, NOX and CO2 formation is presented, these being the main pollutants emitted in the cement industry gas stream Several technologies for reducing NOX, SOX and CO2 emissions in long wet kilns are introduced: primary measures preventing contaminant formation and secondary/tube end emission reduction measures. Strategies for preventing CO2 (green-house effect gas) formation are also addressed, such as fuel and raw material substitution and CO2 capture technologies which are still being developed.
Keywords : cement kiln; greenhouse effect; pollution control; NOX; SO2; CO2.
