含油污泥在石油开采过程中广泛产生,storage,交通运输,和精炼,并且在老化过程中变得更加稳定。老化含油污泥的界面稳定性阻碍了石油资源的回收和处置。本文综述了老化含油污泥的界面膜稳定性,这是通过在重质组分(沥青质和树脂)和无机颗粒之间形成粘弹性和刚性双层界面膜而发生的。双层界面膜增强了界面膜强度,阻碍了液滴的聚集,有助于形成稳定和高粘度的油-水-固体三相混合物。最近用于降低界面膜稳定性的破乳技术分类如下:去除重质组分,改变沥青质骨料结构,降低无机颗粒含量。通过深入分析沥青质和树脂的微观结构和界面性质,有望开发出更有效的破乳技术。以及全面研究各种成分之间复杂的相互作用。这篇综述在稳定机制和相应的失稳方法之间架起了桥梁,这将促进未来老化含油污泥处理的研究。
Oily sludge is widely produced in the processes of petroleum exploitation, storage, transportation, and refining, and becomes more stable during aging. The interfacial stability of aging oily sludge hinders the recovery and disposal of oil resources. This review summarizes the interfacial film stability of aging oily sludge, which occurs through the formation of viscoelastic and rigid bilayer interfacial films between heavy components (asphaltenes and resins) and inorganic particles. The bilayer interfacial films enhance interfacial film strength and hinder the aggregation of droplets, contributing to the formation of a stable and high-viscosity oil-water-solid three-phase mixture. Recent demulsification technologies for reducing the stability of interfacial films have been classified as follows: removing heavy components, changing asphaltene aggregate structure, and reducing inorganic particle content. More efficient demulsification technologies are expected to be developed by deeply analyzing the microstructure and interfacial properties of asphaltenes and resins, as well as comprehensively studying the complex interactions among various components. This review constructs a bridge between the stability mechanism and the corresponding destabilization methods, which would promote future studies in aging oily sludge treatment.
