| Abstract: | This study evaluates effectiveness of 4 additives [CaO,
Ca(OH)2 + NaHCO3, H2O2, and FeSO4 + H2O2] in thermal
degradation of hazardous polycyclic aromatic
hydrocarbons (PAHs) in petroleum sludge cake. Residual concentrations of 16
priority PAHs were determined using GC-MS. Total PAH conc. was found as: gas,
3.11 × 10-4 - 4.36 × 10-4 ppmv; particulate, 7.92 × 10-5 - 5.24 × 10-4 mg/m3; and residue, 1.37 × 10-4 - 1.07 × 100 μg/g. Total toxicity equivalence of PAHs
relative to that of benzo[a]pyrene (BaP) was found as: gas, 3.11 × 10-7 - 4.41 × 10-7; particulate, 3.87 × 10-7 - 3.85 × 10-5; and residue, 6.17 × 10-7 - 9.65 × 10-3. Ca(OH)2 + NaHCO3 was most suitable due to least emission of high
molecular weight PAHs, lower equivalent carcinogenicity of products, and lower
concentrations of PAHs in gas, particulate and residue. |
