Cyclopentane hydrate cohesion measurements and phase equilibrium predictions

摘要

Clathrate hydrates can form in oil and gas flowlines at high pressures and low temperatures. These solids frequently form under flowing conditions, where they can encounter other hydrate particles due to turbulent mixing. Hydrates may also form in locations where they can anneal significantly before coming in contact with other hydrate particles, such as during transient shut-in conditions in a flow line. Understanding the effect of different shut-in/annealing time periods on hydrate cohesive forces can be important in providing further insight into effective strategies to prevent hydrate plug formation.
