Natural gas hydrates in flow assurance

Nr 5

7--11

This work focuses on hydrate formation in natural gas pipelines, which is considered as the principal flow assurance problem. A hydrate phase equilibrium model is combined with a transient gas flow model to monitor if, where, and when natural gas in pipelines enters the hydrate formation region. The hydrate model is based on phase equilibria in systems with natural gas containing free and dissolved water. A transient gas flow model is used to describe the flow conditions in natural gas pipelines. This approach enables pipeline operators to monitor the risk of hydrates under normal and emergency conditions, but also to estimate the optimal trade-off between different hydrate prevention techniques. To show the applicability of the method a case study is conducted for a subsea pipeline.
