Injection of large volumes of Monoethylene Glycol
(MEG) at the wellhead is an effective way to prevent
hydrate formation and assure gas flow. Rich MEG
typically 30-40% returns in a mix of gas,
hydrocarbons, water, salts and other solids;
replacement is very costly and the installation of
MEG Regeneration and Reclaiming system provides the
following benefits: reduction in purchased volume of
new glycols, protection against hydrate formation
and pipeline freeze-up, lower corrosion of subsea
and onshore flowlines, reduced fouling and scaling,
smaller circulating volumes in glycol loop.
To prevent formation of hydrate in transmission
lines or processing equipment, Lean MEG typically
70% concentration is injected in the lines carrying
Natural Gas.
