Synthesis and Preparation of Desulfurization Concerned Naphthenic Acid Type Ionic Liquid

Abstract:

This paper describes the types and characteristics of ionic liquids, synthesis and application of ionic liquids in chemical and environmental applications, and naphthenic acid corrosion problems and research on ionic liquids are organically combined together, using properties, good stability and easy separating from crude oil, of ionic liquid generated by imidazole and naphthenic acid, exploring the ionic liquid deacidification process conditions and acid removal effect. The naphthenic acid and imidazole react in acetone solvent, synthesis a series of ionic liquids in different reaction ratio, reaction temperature, reaction time and stirring speed conditions,makesome physical measurements and calculation of the yield of these ionic liquids and. The results show that, in naphthenic acid and imidazole molar ratio of 1:1, reaction temperature 70°C, reaction time 7h, stirring speed 400R / min, stand half hour after reaction, the yield of naphthenic acid type ionic liquid is maximum, namely, the deacidification effect is best. At the same time measured in the ionic liquid density is 1.179g / mL, and pH is 5.8. Obtained optimum synthesis condition of naphthenic acid type ionic liquid, greatly improving the deacidification rate of high acid crude oil, more importantly, the method does not cause any pollution to the environment.
