Phase Equilibrium Prediction

Currently, there is uncertainty in the quality of both hydrate and solid hydrocarbon equilibrium predictions, further, the interactions of these phenomena are poorly understood. At UWA, we have previously deployed a new simulation package in the form of a new GPA approved tool for solid-vapour-liquid equilibrium predictions – CryoFAST. As part of this current project, we aim to expand our predictive capabilities by producing an integrated SVLE / hydrate tool for phase equilibrium predictions, delivered in the form of a DLL compatible with both Excel and external software. When coupled with other work on quantifying the uncertainty in hydrate equilibrium data, this should yield the ability to estimate the distribution of SVLE in subsea pipelines.
