Abstract

Owing to the difficulty in the demulsification of heavy oil-in-water (O/W) emulsions, the demulsification rules of magnetic nanoparticles, microwave radiation, and magnetic-nanoparticle-assisted microwaves were investigated in this study. The surface potential and droplet size of the emulsion under different demulsification conditions were investigated by using a ζ potentiometer and polarizing microscopy to reveal the mechanism of demulsification. The results showed that γ-FeO exhibited the best demulsification performance among the six magnetic nanoparticles used for demulsification. With an increase in the concentration of γ-FeO, the water separation of the heavy O/W emulsion first increased and then decreased, and with a decrease in pH, the demulsification performance gradually increased. The experimental results showed that microwave demulsification had an optimal power. The demulsification efficiency was significantly improved at the synergistic action between magnetic nanoparticles and the microwave, proving that magnetic nanoparticles had a promoting effect on microwave demulsification. In addition, the recycling experiment results showed that the magnetic nanoparticles exhibited good recyclability and reusability. Finally, a temperature field model of the emulsion under the synergistic effect of microwaves and magnetic nanoparticles was established and evaluated. Both before and after the addition of the magnetic nanoparticles, the theoretical temperature of the heavy O/W emulsion was consistent with the experimental temperature at different microwave powers and radiation times.

摘要

由于水包油（O/W）型稠油乳液破乳困难，本研究考察了磁性纳米颗粒、微波辐射以及磁性纳米颗粒辅助微波的破乳规律。利用ζ电位仪和偏光显微镜研究了不同破乳条件下乳液的表面电位和液滴尺寸，以揭示破乳机理。结果表明，在所使用的六种用于破乳的磁性纳米颗粒中，γ-FeO表现出最佳的破乳性能。随着γ-FeO浓度的增加，稠油O/W乳液的水分离率先升高后降低，随着pH值的降低，破乳性能逐渐提高。实验结果表明，微波破乳存在最佳功率。磁性纳米颗粒与微波协同作用时，破乳效率显著提高，证明磁性纳米颗粒对微波破乳具有促进作用。此外，循环实验结果表明，磁性纳米颗粒具有良好的可回收性和再利用性。最后，建立并评估了微波和磁性纳米颗粒协同作用下乳液的温度场模型。在添加磁性纳米颗粒前后，不同微波功率和辐射时间下稠油O/W乳液的理论温度与实验温度均一致。
