GOLATO, Marcos A. et al. Monitoring of effluent particulate matter emitted by sugarcane factory stacks in Tucumán. Rev. ind. agric. Tucumán [online]. 2012, vol.89, n.1, pp.11-19. ISSN 1851-3018.

Total particulate matter (TPM) concentrations were measured in stack fumes from sugar factory steam generating boilers in Tucumán in 2008, 2009, 2010 and 2011. The objective of this work was to monitor the evolution of TPM concentrations and emissions and observe the efficiency of filtration systems used in sugarcane factory stacks. Average values of 58.5 kg/h, 33.6 kg/h, 47.6 kg/h and 33.9 kg/h were obtained in 2008, 2009, 2010 and 2011, respectively. Bagasse boilers were also meticulously surveyed to obtain data of the evolution of emissions in relation to specific operation variables of the boilers. Data concerning the quality of effluent gasses from the stacks demonstrated the influence of maintaining and correctly using filtration media. Decrease in particle concentration was studied in relation to design indices of gas washers, and it was observed that the technological advances introduced into sugar mill equipment design have led to a lesser environmental impact.
