MEG (Mono Ethylene Glycol) is injected to offshore pipelines to inhibit the formation of hydrates in the oil and gas production pipelines and related facilities. MEG Regeneration Package removes water from MEG solution and produced Lean MEG is re-injected to the offshore.
TEG Dehydration Package is used to remove water from the natural gas stream in order to meet the pipeline quality standards. This process is required to prevent hydrates formation at low temperatures or corrosion problems due to the presence of carbon dioxide or hydrogen sulfide (regularly found in natural gas). Dehydration, or water vapor removal, is accomplished by reducing the inlet water dew point. The wet gas is brought into contact with dry glycol in an absorber. Water vapor is absorbed in the glycol and consequently, its dew point reduces.
