(184g) Investigation of Functionalized Spherical Silica As a Hydrate Blockageinhibitor in Water-in- Oil Emulsions Under Quiescent and Flowing Conditions
engineering with crystalline structures forming in water-in- oil emulsions under low
temperatures and high pressures often leading to pipeline blockages. Ludox TM-50 and
powdered spherical silica particles will be surface treated to hydrophobize the particles for
use as a stabilizer in water-in- oil emulsions to investigate their effect on hydrate formation.
The first analysis of hydrate formation in water-in- oil emulsions stabilized using silica
particles will be using optical microscopy and particle distribution characterization
techniques. Experiments will test the effect of various water cuts, temperatures, and
concentration of solid particles.
After a fundamental understanding of the behavior of silica particle stabilization is
reached, the focus will shift to analyzing water-in- oil emulsion behavior under flowing
conditions using a flow loop system. These experiments are expected to determine the
utility of the Ludox TM-50 and powdered silicon dioxide particles as a method of hydrate
inhibition and understand their effect on hydrate formation under both quiescent and
flowing conditions. Work on this project is ongoing.
