Abstract:
Porous polymeric foams are well-known materials and have been produced by a wide variety of techniques ranging from leaching soluble fillers through gas-blowing to phase separation. Although these materials are widely used, their structure is often irregular and difficult to control. However, a novel method for producing porous materials with a more regular structure has been developed based on high internal phase emulsions (HIPE). These foams are called emulsion-derived foams and are commercially known as Polyhipe® (Unilever) polymers.If one takes a liquid oil, introduces water and a suitable

Abstract:
n-Hexadecane-in-water emulsions were investigated by electroacoustics using a prototype of an AcoustoSizer-II apparatus. The emulsions were formed by passing the stirred oil/water mixture through a homogenizer in the presence of sodium dodecyl sulfate (SDS) at natural pH (6–7). With increasing oil-volume fraction, the particle size increased linearly after 5 and also after 20 passages through the homogenizer, suggesting that surface energy was determining particle size. For systems in which the surfactant concentration was limited, the particle size after 20 passages approached the value dicta

For the first time, the inverse, no less urgent, task of influencing the field oil-water emulsion (OWE) has been solved — not to destroy the OWE and decompose it into oil and water (a direct task), but to create a stable emulsion, while its viscosity should be significantlyreduced. The electrohydraulic effect was used to influence on OWE — the formation of a shock wave as a result of a pulsed plasma electrohydraulic discharge (PAED) in a liquid (electrohydraulic shock — E-shock).

The paper presents the results of hydrodynamic studies of inverse water hydrocarbon dispersions: emulsions and, prepared from it by freezing the dispersed phase, suspension. In addition to the high viscosity of the emulsion, a much higher viscosity of the carrier phase, the success of the use of invert emulsions in the oil industry is due to the dynamic blocking effect. The effect is that the flow velocity in the capillary structures and cracks decreases by 3-4 orders of magnitude, in spite of the constantly acting pressure drop.

One of the main uses of water in oil emulsions in the petroleum industry is oil-based drilling fluids due to their rheological characteristics and various functions to keep a good drilling process. To achieve these characteristics many researches have been made to establish various formulations to reply to the technical needs and also to reduce the cost of these drilling fluids and their environmental effects.

Abstract:
Adsorbed solid particles can stabilize (Pickering) emulsions and multiple emulsions very effectively. For roughly equal volumes of oil and water, together with solid particles, the ‘preferred’ emulsion type depends on the relative wettability of the particles by oil and water. Hydrophobic particles tend to stabilize W/O emulsions whereas hydrophilic particles favour O/W emulsions. Emulsions can be inverted from one type to the other either by changing the liquid volume fractions or the (mean) wettability of the particles. The latter method is analogous to changing the HLB in surfactant-stabili

Water-in-oil emulsions are commonly unavoidable and undesirable in the production, transportation, and refining of petroleum and related products. The emulsions are stabilized by a variety of surface-active compounds found in crude oil such as natural surfactants and fine mineral particles. A critical step in the processing of crude oil is to break the interfacial film formed at the oil/water interface to enable the coalescence and separation of water from oil. Demulsifiers are commonly used to promote the water removal process. However, the effectiveness of a demulsifier varies greatly due to
