The Kinetics of Hydrate Blockage Formation in Oil-Dominated Pipelines: The overall objective of this work is to incorporate experimental conclusions regarding the kinetics of hydrate formation and agglomeration into the hydrate kinetic model, CSMHyK. Laboratory experiments, such as a semi-batch autoclave cell apparatus, and pilot-scale flow loop experiments along with modeling and computer simulation will be used in this work. The hypothesis that will be tested states hydrates in water in oil dispersions first form as a hydrate shell and further formation is limited by diffusion of gas through the shell. The other hypothesis is that hydrate aggregation is a time dependant phenomena that is controlled by the collision frequency of particles in the system. Also, the maximum size a hydrate agglomerate can achieve depends on a force balance between the adhesive force between hydrate particles and the shear force exerted on the aggregate.
