In this paper, the basic concept of surfactants as chemical additives and their diversified classification system are first expounded, laying a theoretical foundation for the subsequent study of their application in demulsification technology. Then, the specific application cases of various types of surfactants in the field of demulsification are deeply analyzed, and ways in which they achieve effective separation of emulsions through their unique physical and chemical properties are revealed. Further, the internal action mechanism of surfactant demulsifier, including how to destroy the stability of emulsion and promote the separation of oil and water phase, is systematically described. On this basis, the significant advantages of surfactant demulsifier compared with traditional methods are summarized, including high cost-effectiveness, high demulsifier efficiency, strong stability, wide adaptability, and easy operation. Finally, the development direction and challenges of surfactant demulsifier in the future are prospected.
