三元复合驱体系油相中阴离子表面活性剂的分离方法

Separation Method of Anionic Surfactant from Crude Oil in ASP Systems

建立了一种快速、简便将驱油用阴离子表面活性剂从原油中分离出来的方法。即在极性硅胶柱上 ,用不同极性的溶剂淋洗分离 ,阴离子表面活性剂集中在淋洗液中。用指示剂法及红外光谱法对分离情况进行了监测 。

Set up a new, easy method to separate anionic surfactant which is used in oil enhanced recovery from oil. By using a polar silica column, eluting with a series of organic solvents with increasing polarity, separate the surfactant from other oil components completely. Detect the results by methylene blue acidic indicator and IR spectroscopy. It proved the method is effective and practical.
