Abstract
In the past few years, the number of studies regarding the application of ionic liquids (IL) as alternative solvents to extract value-added compounds from crude oil fractions has been growing. Ionic liquids can be considered as green solvents due to their very low vapor pressure and wide range of applications with unique physical and chemical properties. In petroleum and hydrocarbon industries, various solvents have been used for treating purposes. However, these solvents have their own limitations as environmental and economical issue. These limitations can be overcome by use of ionic liquids. This paper gives a survey on the latest most popular IL, from their applications to their feasible results in refinery and petrochemical streams. Especially the selective treatment of the Azerbaijan’s crude oil fractions by IL was highlighted and achieved practicable and suitable results were indicated.
