离子液体在石油化工行业的应用

Application of Ionic Liquids in Petrochemical Industry

离子液体是一种无色、无异味、可以重复使用、完全由离子组成的新型“绿色溶剂”,有着不挥发、低蒸气压和宽泛的温度范围等优点。在石油化工行业中,离子液体常因其物理和化学特性被用来加入地层中提高原油的产量,或是被当作一种新型表面活性剂添加到原油生产过程的乳状液之中,造成破乳效用。对离子液体的继续研究和创新,会更深切认识其发展的必要性。

Ionic liquid is a new type of"green solvent"which is colorless,odorless,reusable and completely composed of ions.It has the advantages of non-volatile,low vapor pressure and wide temperature range.In the petrochemical industry,ionic liquids are often used to add into the formation because of their physical and chemical properties to improve the output of crude oil,or it is added to the emulsion formed by crude oil production as a new surfactant to cause demulsification.The continuous research and innovation of ionic liquids will further be helpful to understand the necessity of its development.
