oil in water and water in oil emulsion difference

When water and oil in a reservoir enter the well bore through. To increase viscosity of water in oil emulsions, you have to increase viscosity of oil phase only, whereas you can use rheological modifiers to thicken water phase in oil in water emulsions to increase viscosity. Rather, it is formed when oil and water are produced together with a great amount of agitation.In making water in oil emulsions, you test the ph of the water phase ingredients and adjust appropriately, whereas in oil in water emulsions you check and adjust ph at the end of the emulsion process.Sorbitan stearate, lecithin, lanolin/lanolin alcohols, and glyceryl monooleate are some examples of viable w/o emulsifiers. However, because the hydrophilic balance must be within a range of approximately 3-6, there is a limited number of emulsifiers to select from. Polysorbate, sorbitan laurate, and cetearyl alcohol are just a few examples of emulsifiers that are compatible with o/w emulsions. In addition to these, there are multiple or complex. Water-in-oil (W/O) emulsion has small water droplets dispersed in oil as a continuous phase, which is oil-soluble and difficult to disperse in water 35. All emulsions, whether o/w or w/o, require an emulsifier to provide them with stability o/w emulsions often require more than one emulsifier for optimal stability, but a variety of emulsifiers exist to suit this function. A oil-in-water (O/W) emulsion has a continuous phase of water and a dispersed phase of oil, which is highly soluble in water.Therefore, it is important to evaluate the effect of water on thermodynamic (density) and transport (viscosity) properties oilwater emulsions. Water is present in almost all steps of crude oil production including exploitation, upgrading, transportation and processing (see also Sect. In contrast, emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for w/o emulsions. How do you distinguish a W/O from an O/W emulsion In this video we show a few simple ways to distinguish and to understand the difference between these two. Oilwater emulsions are generated from many different industrial processes, including petroleum production (exploitation processing, refining, storage, and. 2.1.3 Water-in-Oil Emulsion Preparation and Stability. Emulsifiers with HLB values greater than 10 are more hydrophilic and thus better at stabilizing o/w emulsions. The HLB scale ranges from 0 to 20, with 10 corresponding to an emulsifier that is equally attracted to water and oil.

However in a water in oil emulsions, the water droplets (internal phase)are dispersed in the (external oil phase )and it is important here that the water phase is actually poured into the oil phase to form a stable emulsion. It doesn’t mater which phase is poured into which in an oil in water emulsion. In oil in water emulsions, the oil droplets are dispersed in the water phase.
