EMULSIFICATION OF OIL SAND BITUMEN IN CAUSTIC SOLUTION

Bitumen in the form of concentrated bitumen-in-water emulsion can be transported using a pipeline. Froth, which is a product of water based extraction of bitumen from oil sands, can be emulsified using NaOH. The emulsion can then be inverted by lowering pH to recover the bitumen. NaOH concentration, salt concentration, temperature, and mechanical energy input affect the formation of the emulsion and its viscosity. Optimum conditions for emulsion formation and inversion were specified.

Characterization of Physico-Chemical Properties of Oil/Water Systems: Interfacial Behavior Prediction

The tractability of petroleum is intimately related to the type of emulsion that is formed during its production. The characteristics of water/oil and oil/water emulsions depend on some factors such as the density and the composition of the oil. In this work, the properties of oils coming from the Campos Basin, Brazil, were evaluated by means of water-in-oil emulsion physico-chemical, interfacial, and characterization tests. Such properties have been correlated with the tractability of the petroleum in order to establish a behavior prediction method based on the properties of such petroleum. The main tool used in this work was the chemiometry technique. Through this method, it was possible to conclude that density, viscosity, surface tension, and nickel content were the properties that influenced the separation of the oils. Density, pour point, initial temperature of crystal formation (TIAC), characterization factor, and nitrogen content were the properties that influenced the diameter of the emulsion drops.     

Characterization of Physico-Chemical Properties of Oil/Water Systems: Interfacial Behavior Prediction

Abstract

The tractability of petroleum is intimately related to the type of emulsion that is formed during its production. The characteristics of water/oil and oil/water emulsions depend on some factors such as the density and the composition of the oil. In this work, the properties of oils coming from the Campos Basin, Brazil, were evaluated by means of water-in-oil emulsion physico-chemical, interfacial, and characterization tests. Such properties have been correlated with the tractability of the petroleum in order to establish a behavior prediction method based on the properties of such petroleum. The main tool used in this work was the chemiometry technique. Through this method, it was possible to conclude that density, viscosity, surface tension, and nickel content were the properties that influenced the separation of the oils. Density, pour point, initial temperature of crystal formation (TIAC), characterization factor, and nitrogen content were the properties that influenced the diameter of the emulsion drops.     

Modeling of flow of oil-in-water emulsions through porous media

Formation and flow of emulsions in porous media are common in all enhanced oil recovery techniques.In most cases,oil-in-water(O/W) emulsions are formed in porous media due to oil-water interaction.Even now,detailed flow mechanisms of emulsions through porous media are not well understood.In this study,variation of rate of flow of O/W emulsions with pressure drop was studied experimentally,and rheological parameters were calculated.The pressure drop increases with an increase in oil concentration in the O/W emulsion due to high viscosity.The effective viscosity of the emulsion was calculated from the derived model and expressed as a function of shear rate while flowing through porous media.Flow of O/W emulsions of different concentrations was evaluated in sand packs of different sand sizes.Emulsions were characterized by analyzing their stability,rheological properties,and temperature effects on rheological properties.
