Abstract
The extraction of sulphur containing compounds from hydrocarbon matrixes plays an important role in refinery processes. A number of studies have been reported aiming at using ionic liquids (ILs) for this purpose. The endless combination of ILs ions allows the fine tune of their properties and the building of task-specific ILs with enhanced performance for specific operations. COSMO-RS is a predictive method based on unimolecular quantum calculations that is here evaluated for the prediction of the liquid-liquid equilibria between ILs and hydrocarbons aiming at understand the influence of the ILs structure on the phase behavior. It is shown that COSMO-RS provides a good qualitative description of the data available and can be used for screening ILs for use in extraction processes.
