Gas Hydrate Analysis and Modelling of Monoethylene Glycol Regeneration and the Impact of Additives
MetadataShow full item record
Monoethylene glycol (MEG) is injected to inhibit gas hydrate formation. In this study, significant experimental and computational effort has been applied to investigate MEG degradation, the regeneration and reclamation process during water breakthrough, and to produce empirical models. Hydrate phase equilibria of numerous corrosion inhibitors, oxygen scavengers, amines and scale inhibitors were produced suggesting an inhibitory effect on gas hydrates predominantly. Furthermore, the impact of methyldiethanolamine (MDEA) was modelled empirically and thermodynamically.
