Glycol hydrate
WebThis book addresses several issues related to hydrate inhibition and monoethylene glycol (MEG) recovery units (MRUs) in offshore natural gas fields, from fundamentals to engineering aspects and from energy consumption assessment to advanced topics such as exergy analysis. WebMonoethylene glycol (MEG) is widely used by the oil and gas markets in wellheads and pipelines to prevent hydrate formation at pipeline conditions. In offshore deepwater gas production facilities, where the exposure to lower temperatures in subsea pipelines is common, MEG is used for hydrate inhibition.
