Liu J, Zhang Y, Peng K, Zhao X, Xiong Y, Huang X. A review of the interfacial stability mechanism of aging oily sludge: Heavy components, inorganic particles, and their synergism. JOURNAL OF HAZARDOUS MATERIALS 2021; 415:125624. [PMID: 33740725 DOI: 10.1016/j.jhazmat.2021.125624] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 03/05/2021] [Accepted: 03/07/2021] [Indexed: 06/12/2023]
Abstract
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.

Abstract
In this study, SHT (switchable-hydrophilicity triethylamine, [Et₃NH]·[HCO₃]) has been synthesized and instrumentally characterized by Fourier transform⁻infrared spectroscopy (FTIR) and 13C nuclear magnetic resonance (NMR). The operational synthesis conditions of SHT were optimized and determined at 25 °C, Et₃N/H₂O volume ratio of 1:2 and CO₂ injection rate at 300 mL/min. When it was used to extract heavy oil from unconventional oil ore, it was found that it could break maltenes-in-water emulsions. When asphaltenes were present in the oil phase, it was observed that SHT could cooperate with asphaltenes. These results indicated that SHT works with asphaltenes, leading to synergistic effects in stabilizing oil⁻water (o/w) emulsions.
