摘要
By screening solvents and surfactants,a surfactant with strong wetting and dispersing ability has been discovered,which can form stable emulsions.An O/W emulsifier that can inhibit paraffin deposition and remove it has been acquired by an orthogonal design of experiment.The density of the emulsion is 0.9 g/cm3,the removal rate of paraffin is 150 g/（mL·min）,and the inhibiting rate of paraffin is 20.70%.When 0.8%～1.5%（mass fraction） sodium chloride is added to the emulsion,the deemulsification time is 1.5～4.0 h.
By screening solvents and surfactants, a surfactant with strong wetting and dispersing ability has been discovered, which can form stable emulsions. An O/W emulsifier that can inhibit paraffin deposition and remove it has been acquired by an orthogonal design of experiment. The density of the emulsion is 0. 9 g/cm^3, the removal rate of paraffin is 150 g/（mL ·min）, and the inhibiting rate of paraffin is 20. 70%. When 0. 8% - 1.5% （mass fraction） sodium chloride is added to the emulsion, the deemulsification time is 1.5-4.0 h.
