Formation of emulsion

WebSize emulsion made ultrasonically shows a strong similarity in range 8 to 4 nm physical characteristics, except that the ultrasonic emulsion has a more uniform water drop size distribution. One method being studied for improving combustion systems by reducing particulate emissions is the use of REFERENCES water/oil emulsions as a fuel ‘-‘. WebJun 29, 2015 · Crude-oil/brine emulsions are stabilized by the presence of surfactants and colloidal particles such as clays, paraffins, and asphaltenes. In general, organophilic particles such as paraffins and asphaltenes favor the formation of oil-external emulsions and sludges. Water-wet solids such as clays favor the formation of water-external …

WebEmulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomer, and surfactant. The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
