Polycyclic Aromatic

Polycyclic aromatic hydrocarbons (PAHs) are mutagenic and carcinogenic contaminants made up of fused benzene rings. Their presence has been reported in several wastewater streams, including produced water (PW), which is the wastewater obtained during oil and gas extraction from onshore or offshore installations. In this study, ferrate (VI) oxidation was used for the first time for the treatment of 15 PAHs, with the total concentration of 1249.11 μg/L in the produced water sample. The operating parameters viz., ferrate (VI) dosage, pH, and contact time were optimized for maximum removal of PAHs and chemical oxygen demand (COD). Central composite design (CCD) based on response surface methodology (RSM) was used for optimization and modeling to evaluate the optimal values of operating parameters. PAH and COD removal percentages were selected as the dependent variables. The study showed that 89.73% of PAHs and 73.41% of COD were removed from PW at the optimal conditions of independent variables, i.e., ferrate (VI) concentration (19.35 mg/L), pH (7.1), and contact time (68.34 min). The high values of the coefficient of determination (R2) for PAH (96.50%) and COD (98.05%) removals show the accuracy and the suitability of the models. The results showed that ferrate (VI) oxidation was an efficient treatment method for the successful removal of PAHs and COD from PW. The study also revealed that RSM is an effective tool for the optimization of operating variables, which could significantly help to reduce the time and cost of experimentation.

The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs), which are on the United States Environmental Protection Agency (US EPA) priority pollutant list, were studied in ten different soil samples from Shengli Oil Field, China. The total PAHs concentrations in the sampled soils attained 1214.9–2965.1 ng/g (2159.6 ng/g on average). The highest total PAHs concentration was in the soil with a huge content of oil sludge, while the lowest was in fine soil environment areas. The soil contamination with PAHs in the study areas was classified as severe. The major pollutants were naphthalene, phenathrene, fluorine (Flu), pyrene (Pyr), while the detected concentration of benzo(a)pyrene (BaP), benzo(b)fluoranthene was relatively low. Among the 16 kinds of PAHs, the concentration increased in the order: 6 rings < 5 rings < 4 rings < 2 rings < 3 rings. The ratios of Flu/(Flu + Pyr) and indeno benzene(1,2,3-c,d)pyrene (IP)/(IP + BaP) were 0.46–0.48, and 0.36–0.64, respectively. Our results suggest that the main sources of PAHs were petroleum extraction and petroleum combustion. In addition, a small amount of PAHs originated from combustion of grass, woods, and coal.
