Chemical Demulsification of Water-in-Crude Oil Emulsions

Figure 1 and 2 shows separation of water and oil from water-in-oil emulsions as a function of time, respectively. As shown in Fig. 1 and 2 , all amine groups showed the water and oil separations. This could be attributed to a very specific interaction between the amine added and the naturally occurring constituents in the interfacial film.

Crude-Oil-Water Emulsions to Improve Fluid Flow in an Oil

A field test was conducted to see if oil-in-water emulsions, prepared from petroleum crude oils, would reduce water channeling from injection to producing wells. In a two-year period after emulsion treatment of three water-injection wells, fluid production from offset wells showed increased oil recovery and lower water-oil ratios.

Heavy crude oil viscosity reduction and rheology for pipeline

Generally, emulsions are of great interest in many industrial applications. The formation of oil-in-water emulsion (i.e. O/W emulsion) is one of the alternatives to enhance the flowability of crude oil through the pipelines. That is why it is very important to study the flow behavior of the O/W emulsion.

Enhanced effectiveness of oil dispersants in destabilizing

Oil impacting the northern Gulf of Mexico shoreline from the 2010 Deepwater Horizon accident was predominantly in the form of water-in-oil emulsions (WOE), a chemically weathered, highly viscous, neutrally buoyant material. Once formed, WOE are extremely difficult to destabilize. Commercially-available oil dispersants are largely ineffective de-emulsifiers as a result of the inability of

Functionalized Cellulose Networks for Efficient Oil Removal

The separation of oil from water in emulsions is a great environmental challenge, since oily wastewater is industrially produced. Here, we demonstrate a highly efficient method to separate oil from water in non-stabilized emulsions, using functionalized cellulose fiber networks. This is achieved by the modification of the wetting properties of the fibers, transforming them from oil- and water
