The present study dealt with the application of biodegradable demulsifier synthesized based on Helianthus annuus (sunflower oil). The synthesized demulsifier is characterized using Fourier-transform infrared, nuclear magnetic resonance, and thermogravimetric analysis. The demulsification process was designed, modeled, and optimized through the response surface methodology. Furthermore, the significance of the developed models and operating parameters was evaluated using analysis of variance. The results indicated that the proposed models were highly significant, with a p-value of <0.0001. The demulsification efficiency (DE) of 100% was achieved at the following optimal conditions: 185.2 ppm demulsifier concentration, 70 °C temperature, and 55.3 min settling time. The interfacial activity, particle size analysis, and viscosity of the emulsion were measured, and optical microscopic analysis was conducted to directly observe the demulsification process. The study also compared the DE of prepared and field emulsions. Moreover, the synthesized demulsifier is degraded in 14 days. This research provides a promising solution for the treatment of water-in-oil emulsions.

向日葵合成的新型可生物降解破乳剂在原油破乳中的应用─基于RSM的实验和建模方法
本研究涉及基于向日葵（葵花籽油）合成的可生物降解破乳剂的应用。使用傅里叶变换红外、核磁共振和热重分析对合成的破乳剂进行了表征。通过响应面方法对破乳过程进行设计、建模和优化。此外，使用方差分析评估了所开发模型和操作参数的重要性。结果表明，所提出的模型具有高度显着性，p值<0.0001。在以下最佳条件下实现了 100% 的破乳效率 (DE)：185.2 ppm 破乳剂浓度、70 °C 温度和 55.3 分钟沉降时间。测量乳液的界面活性、粒径分析和粘度，并进行光学显微镜分析以直接观察破乳过程。该研究还比较了制备乳液和现场乳液的 DE。而且合成的破乳剂在14天内就降解了。这项研究为油包水乳液的处理提供了一种有前景的解决方案。
