Recent development in the treatment of oily sludge from petroleum industry: A review
TL;DR: The origin, characteristics, and environmental impacts of oily sludge were introduced and no single specific process can be considered as a panacea since each method is associated with different advantages and limitations.

Water-in-Crude Oil Emulsion Stabilization: Review and Unanswered Questions
TL;DR: Several of these means of emulsion and thin-film stabilization of emulsions in petroleum-water mixtures are reviewed in this paper, as well as some of the key physical and chemical means of characterizing both the materials that stabilize the emelsions and the means of charactersizing the oil-water interface and the emulsion films themselves.
Journal ArticleDOI
Crude oil emulsion: A review on formation, classification and stability of water-in-oil emulsions
TL;DR: In this article, the authors reviewed the current state of understanding in the formation, classification and stability of crude oil emulsification, focusing on water-in-crude oil emulsion.
Journal ArticleDOI
Stability of water/crude oil emulsions based on interfacial dilatational rheology
TL;DR: It is shown that such a gel can also form in the absence of asphaltene in the oil phase, and the stability of emulsions was found to increase with both the gel strength and the glass transition temperature of the gel.
Journal ArticleDOI
Overview on petroleum emulsions, formation, influence and demulsification treatment techniques
TL;DR: The most challenging aspect in petroleum industry is high produced water accompanying crude oil extraction, which sometimes cause poisonous impact on the environment as discussed by the authors. But, there are several techniques to treat produced water.

Screening of Crude Oils for Asphalt Precipitation: Theory, Practice, and the Selection of Inhibitors
TL;DR: In this paper, a simple method to screen crude oils for their tendency to precipitate asphalt, which may cause problems during production, is described, based on a thermodynamic model of asphalt solubility, derived earlier by Flory and Huggins.

Dewatering of crude oil emulsions 1. Rheological behaviour of the crude oil—water interface
TL;DR: In this paper, the effects of temperature and the presence of surface active demulsifiers on Buchan crude oil rheological properties have been evaluated, and free oscillation and creep modes have been used, depending on the relative viscoelastic behaviour of the films.

Particle—fluid interactions with application to solid-stabilized emulsions part I. The effect of asphaltene adsorption
V.B. Menon,Darsh T. Wasan +1 more
TL;DR: In this paper, the effect of asphaltenes on the contact angle at the water/oil/solid interface and on the zeta potential of the particles was investigated, and the hydrophobic nature of the solids was found to be directly related to the amount of adsorbed on their surface.
