Resumo:As borras oleosas são formadas durante as operações de produção, transporte, armazenamento e na refinaria de petróleo. A análise elementar foi realizada com amostras de borra oleosa de petróleo coletadas no Estado do Rio Grande do Norte. Para o elemento carbono e o hidrogênio foram observadas pequenas diferenças entre os mesmos, mas para o elemento oxigênio foram observadas diferenças maiores entre as amostras de borra. As mesmas apresentaram diferenças na composição química da parte inorgânica e orgânica. A borra do separador água e óleo (SAO) 2 apresentou uma elevada quantidade de óleo (94,88%), essa pode ser considerada um resíduo de elevado valor agregado para a indústria de petróleo. Nas análises de saturados, aromáticos, resinas e asfaltenos (SARA), a borra do descarrego apresentou uma elevada quantidade de saturados. O material inorgânico separado da borra do SAO 2 foi caracterizado e apresentou muito enxofre (41,57 %). As borras analisadas apresentaram elevado valor de componentes orgânicos, logo esse material pode ser tratado e reprocessado em unidades de processos na indústria de petróleo.Palavras-chave: Borra Oleosa; Petróleo; Degradação; Resíduo; Meio Ambiente.
AbstractThe petroleum oily sludge is formed during the production, transportation, and storage processes as well as in the oil refinery plant. The elemental analysis was performed with samples of petroleum oily sludge collected in the State of Rio Grande do Norte. For the carbon and hydrogen elements, small differences were observed between them, but for the oxygen element, bigger differences between the sludge samples were noticed. They have presented differences in the chemical composition of inorganic and organic parts. The sludge from oil-water separator (OWS) 2 showed a high amount of oil (94.88%), being considered a high value-added residue by the oil industry. In the analyses of saturated, aromatics, resins, and asphaltenes (SARA) components, the sludge from the unloading had a high amount of saturates. The inorganic material separated from the sludge of the OWS 2 was characterized, and presented a lot of sulfur (41.57 %). The sludge analyzed showed a high value of organic components, thus such material can be handled and reprocessed in processing units within the oil industry.
The potential of the Al-MCM-41 and Ni/Al-MCM-41 catalysts applied to pyrolysis for the production of renewable hydrocarbons (bio-jet fuel) has been studied and has been shown to be efficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
