Abstract

In this study hydrate formation and deposition measurement for gas-dominated conditions were conducted using a pilot scale flow loop to investigate the effect of mono-ethylene glycol and gas velocity on the pipeline plugging tendency. Quantitative results on hydrate film growth at the pipe wall and deposit sloughing were obtained for the first time from the experimental data using a newly developed numerical model for gas pipelines operating in annular flow regime. This study contributes to the development of a multiphase flow model in the presence of hydrates to enable predictions of gas pipeline blockages and mitigation methods in the field.
