Resumo: Recently, many natural gas reserves with promising energy potencial were found mainly in marine environments. However in these environments is a typical problem production and transportation of natural gas is the occurrence of gas hydrates, which can result in risks for these operations. To avoid the deposition of gas hydrate in both pipelines and deep water wells, the temperature and pressure range of hydrate formation should be predicted to take precautionary measures to ensure safe operation. The currently work had as objective to analyze and to compare mathematic models of prediction of gas hydrate formation. For the comparative, two models of gas hydrate formation were analyzed using different mathematical methods to calculate the formation temperature and the amount of inhibitor required to avoid hydrate deposition. The first model showed a more effective accuracy when applied in high pressure conditions, due to the second model using a mathematical correlation witch low precision in these parameters. This study made it possible to show the importance of the advances of mathematical models to predict the formation of gas hydrate and consequently to take increasingly efficient measures for prevention.

Porém nesses ambientes um problema característico á produção e transporte de gás natural é a ocorrência de hidratos de gás, que podem resultar em riscos para essas operações. Para evitar a deposição de hidrato de gás tanto em gasodutos quanto em poços de águas profundas, a faixa de temperatura e pressão de formação de hidratos deve ser prevista para se tomar medidas de precaução para garantir a segurança das operações. O presente trabalho teve como objetivo analisar e comparar modelos matemáticos de previsão de formação de hidratos. Para o comparativo foram analisados dois modelos de formação de hidratos de gás que utilizam métodos matemáticos diferentes para o cálculo da temperatura de formação e da quantidade de inibidor necessário para evitar a deposição de hidratos. O primeiro modelo estudado mostrou uma precisão mais efetiva quando aplicado em condições de alta pressão, isso devido ao segundo modelo utilizar uma correlação matemática com baixa precisão quando aplicado nesses parâmetros. Esse estudo possibilitou mostrar a importância dos avanços de modelos matemáticos para previsão de formação de hidratos e assim tomar medidas cada vez mais eficientes para prevenção.Universidade Federal do Rio Grande do NorteUFRNBrasilEngenharia de petróleoAttribution 3.0https://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccessGás Natural,Hidratos de gás, Modelos MatemáticosNatural Gas, Gas hydrates, Mathematical ModelsEstudo de modelos de formação de hidratos de gásinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisporreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNTEXTTarsisTCC.pdf.txtExtracted texttext/plain67141https://repositorio.ufrn.br/bitstream/123456789/39464/1/TarsisTCC.pdf.txt2d4a6bb97961eb6e90b722361b277cf4MD51ORIGINALFormaçãoHidratosGás_Barretos_2018.pdfapplication/pdf1159240https://repositorio.ufrn.br/bitstream/123456789/39464/2/Forma%c3%a7%c3%a3oHidratosG%c3%a1s_Barretos_2018.pdfe19bdaf2a74da1581385bbdeb2356bf4MD52CC-LICENSElicense_rdfapplication/octet-stream9https://repositorio.ufrn.br/bitstream/123456789/39464/3/license_rdf42dd12a06de379d3ffa39b67dc9c7affMD53LICENSElicense.txttext/plain756https://repositorio.ufrn.br/bitstream/123456789/39464/4/license.txta80a9cda2756d355b388cc443c3d8a43MD54123456789/394642022-12-28 12:41:32.02oai:https://repositorio.ufrn.br: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ório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2022-12-28T15:41:32Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false
