... issues in terms of separator efficiency, operating expenditures and potential need for frequent maintenance and/or retrofitting new internals. In mature operations with heavy oils, there can be severe issues with Water-in-Oil and Oil-in-Water emulsion layers. In late life operations, enhanced oil...

The study demonstrated the importance of modeling the droplet size distribution to improve the prediction accuracy and the multiphase behavior in the separator, but the emulsion viscosity was not incorporated in the model even at high water cuts up...

... to the well-known method to separate surfactant stabilized emulsions, i.e., heating. Thus, the main objectives of this work were to identify emulsions resistant to heating and develop a process able to accelerate the separation kinetics of such ultra-tight emulsions. Extensive experimental investigations...

... Abstract This paper presents a novel/cost-effective hydrophobic material based 9-octadecenoic acid grafted graphene (POG) for oil/water separation. Graphene derived from graphite was modified with 9-octadecenoic acid to obtain 9-octadecenoic acid grafted graphene (OG). Then, emulsion...

... This document is an expanded abstract. Summary Superhydrophilic materials are of great advantages in the case of oily mixture filtration process. In this study, natural sand particles were characterized and tested for oil in water emulsion separation. The sand particles were characterized...

.... In many other instances, the separator fluid loading may exceed the original design capacity of the vessel resulting in poor oil and water effluent standards. This paper develops a procedure that describes the impact of crude oil emulsion on the efficiency of horizontal separators. The procedure can...

Emulsion Characterization Techniques Abstract This paper presents the first part of an experimental study performed jointly by IFP and Saudi Aramco to characterize the stability of emulsion samples collected from different Saudi Aramco Gas/Oil Separation Plants (GOSP). Earlier studies 1 - 2 have...

... for the highest demulsifier consumption in that GOSP. Higher percent of squeezed wells also results in looser emulsions due to the control of emulsion-stabilizing scales. Generally higher temperatures lead to easier water separation. Higher watercuts increase the possibility of quicker water separation due...

... Abstract Water treatment plants use conventional processes like hydrocyclones and air up-floating equipment to separate oil from water. However, these devices are not effective at removing oil drops with small diameters. In this work, the use of membranes to treat oil-water emulsions...

... Abstract Quantifying oil-water or emulsion separation has always been difficult. This is due, in part, to the numerous factors controlling oil-water separation. This paper describes a new method developed at Saudi Aramco for the quantification of oil-water separation process. It is designated...

To increase the separation efficiency, chemical additives such as demulsifier and anti-foamant are injected into the fluid stream prior its entering into the three phase separators. Demulsifiers are surface-active agents, usually of the non-ionic type, comprising of relatively high...
