The oil and gas industry's flow assurance programs are hampered by gas hydrates. This study focuses on the mechanisms of hydrate formation in natural gas pipelines. The mechanics of water vapour condensation and subsequent water accumulation in lowered parts of a gas pipeline were studied using Computational Fluid Dynamics (CFD). The pipeline temperature profile, condensation of water vapour at walls, hydrate production, and hydrate slurry rheology were all modeled using user defined functions (UDF) incorporated into the CFD software Fluent. Water buildup and hydrate formation were discovered naturally in the uphill sections of gas pipes. CFD has been proved to be an effective technique for deciphering complex physical processes in multiphase flow conditions.
