1D Numerical Simulations of Hydrate Formation and Transport in Oil-Dominated Systems with a Population Balance Framework

摘要

Hydrate management has become a key topic in flow assurance due to the oil & gas production in cold environments (deep waters) and due to the high flow rates of water, especially in brownfields. Considering this, a hydrates formation and transport model is formulated and coupled with a one-dimensional multiphase flow simulator. The hydrate formation and particles size are handled with a Population Balance framework and a more classic framework. For simulations of hydrate-forming oil-dominated flows in an experimental flow loop, the hydrate cut, subcooling, slurry viscosity and water holdup results of each framework were validated, compared and discussed.
