Abstract:Solvent extraction is a promising method for removing
organic sulfides from fuel oils in refineries. However, selecting
an appropriate extractant requires a fundamental understanding of
liquid–liquid equilibria. In this study, we collected liquid–liquid
equilibrium (LLE) data for ternary heptane + thiophene + solvent systems
at 298.2 K and 101.3 kPa. The extraction capabilities of the selected
solvents (ethylene glycol (EG), N-formylmorpholine,
1,3-propanediol, 1,4-butanediol, 1,2-propanediol, N-methyl-2-pyrro… Show more
