Investigation the effect of different ionic liquids based-aryl imidazole on the onset precipitation of asphaltene.

ABSTRACT: Precipitation and deposition of asphaltene are considered as catastrophic issues facing the petroleum industry. Asphaltene deposition mainly occurs at variety places such as formation pore spaces, pumps, pipelines, wellbore, wellhead, tubing, surface facilities and safety valves causing operational problems, production deficiencies and enormous economic losses. This work aims to study the effect of series of synthesized aryl ionic liquids (ILs) containing different alkyl chains, named as R₈-IL, R₁₀-IL, R₁₂-IL, and R₁₄-IL, on the onset precipitation point of asphaltene in crude oil. R₈-IL, R₁₀-IL, R₁₂-IL, and R₁₄-IL were synthesized with high yields (the yield varied between 82 and 88%) and characterized
