Effect of droplet size on the behavior and characteristics of emulsified acid

摘要

Emulsified acids have been extensively used in the oil industry since 1933. Mostof the available research and publications discussed mainly the application of emulsifiedacid in the field. A fair number of the published work also discussed in depth some ofthe emulsified acid properties such viscosity, stability and reactivity. However, all of theavailable research discussed the emulsified acid without sufficient details of itspreparation.Beside their chemical composition, the ways emulsified acids are prepared causesignificant differences in their physical properties. The characterization of emulsifiedacid by its droplet size and size distribution complements its chemical composition andgives the emulsified acid a unique description and thus reproducible properties. Noprevious study considered the impact of the droplet size on the characteristics andproperties of emulsified acid. Therefore, the main objective of this research is to study the effects of the droplet size on various properties of emulsified acid such as viscosity,stability and reactivity.Results showed that the droplet size and size distribution have a strong effect onthe stability, viscosity and diffusion rate of the emulsified acid. The results of this workare important because knowledge of the effect of the droplet size on major designparameters will guide the way emulsified acid is prepared and applied in the field.
