Resumo
Durante a extração do petróleo, são produzidos concomitantemente três produtos: o óleo, a água e o gás. Estes devem ser tratados de acordo com a legislação ambiental vigente. A água que chega até a superfície, é denominada água produzida (AP). Esta será tratada e, por fim, descartada no ambiente marinho. No entanto, na água produzida estão presentes gotículas de óleos e graxas que devem ser removidas antes do descarte. No Brasil, o CONAMA, através da resolução 393/07 que trata da análise de amostras de água produzida de petróleo estabelece como valor máximo mensal de teor de óleo e graxas (TOG) 29 ppm , podendo alcançar valores máximos diários de 42 ppm. Além do TOG, no artigo 10 da mesma resolução, consta a obrigatoriedade de empresas operadoras de petróleo realizarem monitoramento semestral da água produzida, identificando, através de cromatografia, parâmetros como: compostos orgânicos e inorgânicos, radioscópicos e toxicidade. Mais especificamente, na resolução do CONAMA 357/05, levando se em consideração águas salinas (classe 1), consta que a concentração de Carbono Orgânico Total (COT) deve ser de 3ppm e a concentração de fenol (que reage com 4-aminoantipirina) de 0,06ppm. A ideia do nosso trabalho é atingir valores próximos ao COT estabelecido pela legislação por meio de processos oxidativos avançados, com foco nos processos Foto-Fenton e Fotocatálise-heterogênea.
During the extraction of oil, three products are produced concomitantly: oil, water and gas. These should be treated in accordance with current environmental legislation. Water that reaches the surface is called produced water (AP). This will be treated and eventually discarded in the marine environment. However, in the produced water, oil droplets and greases are present, which must be removed before disposal. In Brazil, CONAMA, through Resolution 393/07, which deals with the analysis of samples of oil produced water, establishes a maximum monthly value of oil and grease content (TOG) of 29 ppm, with a maximum daily value of 42 ppm. Besides, TOG, in article 10 of the same resolution establishes it is compulsory for companies operating platform to perform bi-annual monitoring of the produced water, identifying, through chromatography, parameters such as: organic and inorganic compounds, radioscopic and toxicity. More specifically, in CONAMA's resolution 357/05, on the values to be analyzed for saline waters (class 1), that the concentration of Total Organic Carbon (TOC) should be 3ppm and the concentration of phenol (which reacts with 4-aminoantipyrine) of 0.06ppm. The idea of our work is to reach values close to the TOC established by the legislation through Advanced Oxidative Processes, focusing on the processes Foto-Fenton and heterogeneousphotocatalysis.
