According to industry data, the SCBFA in the gas washer exit has
40% humidity. The average concentrations of organic and inorganic
materials obtained in the laboratory using an oven and balance
to dry samples were 33% and 67%, respectively. These
results are close to those shown by TGA measurements (Fig. 3).
Considering the national sugar-cane production in 2008/2009
(BEN, 2009) and that each ton produces 6 kg of ash (FIESP/CIESP,
2001) containing 33% charcoal, the estimated volume of charcoal
that will be produced is greater than one million tons in the 2009
harvest. Because this research about charcoal in SCBA is new, no
reference for this value is available.
