Coupling of a Growth Kinetic Model of Gas Hydrate Formation With Gas-(Water-in-Oil) Slug Flow
Abstract
This article presents the coupling of a crystallization model of gas hydrate formation to a mechanistic gas-liquid slug flow model. Crystallization of gas hydrates occurs within multiphase flow in oil and gas production operations. Mass transfer (gas absorption and convection up to the growing surface) and heat transfer (since gas hydrate formation is exothermic, thus competitive to the driving force required to hydrates to keep forming) limit crystallization under flow. The model is used to understand these competitive phenomena.
