Resumo

O gás propano mundial ou gás liquefeito de petróleo (GLP) tem sido amplamente utilizado para vários fins, como gás refrigerante, combustível, aquecimento; entre outros. Propano é um hidrocarboneto pertencente à família parafina, que é considerado solúvel em algumas substâncias orgânicas. O objetivo desta reflexão é abranger um estudo interpretativo e crítico sobre a solubilidade do propano em dois solventes orgânicos: morfolina N-formyl (NFM) e sulfolane em 298.15, 313.15 e 343.15 K, levando em conta as condições de pressão em obras já concluídas. Este trabalho inclui uma perspectiva físico-química para a análise da pressão e temperatura como os principais fatores quantitativos nos sistemas binários propano (2) + NFM (1) e propano (2) + sulfolane (1); destacando uma análise crítica e global sobre os parâmetros da equação Krichevsky-Ilinskaya (KI). Finalmente, e sob as condições estabelecidas, são discutidos os efeitos da equação de estado de Peng-Robinson (PR EOS), como o parâmetro de interação binária (BIP), a função alfa e algumas modificações.
