What is Meg in oil and gas?
Monoethylene glycol (MEG) is a widely used hydrate inhibitor in the oil and gas industry to reduce the risk of hydrate formation in pipelines that could cause a blockage. For flow assurance and hydrate inhibition purposes, large volumes of MEG are required to control the hydrate formation conditions in pipelines.
What is Meg process?
The OMEGA process (“Only MEG Advantage”) is a process by Shell Global Solutions that is used to produce ethylene glycol from ethylene. This process comprises two steps, the controlled oxidation of ethylene to ethylene oxide, and the net hydrolysis of ethylene oxide to monoethylene glycol (MEG).
What is Meg storage?
Under the proposed concept for a MEG injection system, MEG is temporarily stored in a seabed storage tank and subsequently injected into the subsea flowline. Then, the MEG is recovered as rich MEG from the topside and regenerated as lean MEG through the standard regeneration process.
What is Meg in coolant?
Mono ethylene glycol (MEG) is used as an anti-freeze additive for engine cooling systems to prevent freezing and as an anti-boil additive.
What is Meg solution?
1 Monoethylene Glycol Regeneration and Reclaiming. The condensate may contain MEG solution, which is used for hydrate control in subsea pipelines. The glycol solution is contaminated with salts, corrosion inhibitors, and pipe scales, which must be removed to avoid fouling in the downstream process equipment.
What is Meg regeneration?
MEG regeneration is conducted in a reflux distillation column. The vaporized water passes overhead where it is condensed and collected in the reflux drum. A portion of the water is returned to the distillation column to provide reflux while the remainder is routed to water treatment.
What unit is Meg?
Per meg equals 0.001 permil or 0.0001 percent or parts per million ppm. The unit is typically used in isotope analysis by multiplying an isotope ratio in delta annotation, for example δ18O, by 1000000.
What is Meg regeneration package?
The MEG Regeneration Package for Shwe Field Development Project is designed to treat Rich MEG from the LTSs (topsides Rich MEG) and from Inlet Production Separators (subsea Rich MEG) to the required qualities and conditions through degassing, hydrocarbon and water removal, filtering, heating and pumping in order to …
Is Meg a methanol?
General Information: MEG is a combination of two liquids: methanol, a toxic, low viscosity liquid alcohol used for insecticide, paint stripper, antifreeze and cleaning fluids; and ethylene glycol, an odourless, colourless, toxic liquid of low volatility and viscosity, used for antifreeze and in synthetic rubbers and …
What is the specific gravity of Meg?
Specific Gravity of Ethylene Glycol based Water Solutions
| Specific Gravity- SG – | ||
|---|---|---|
| Temperature | Ethylene Glycol Solution (% by volume) | |
| 0 | -17.8 | 1) |
| 40 | 4.4 | 1.057 |
| 80 | 26.7 | 1.048 |
How is ethylene glycol (MEG) made?
There are two main routes for Ethylene Glycol (Monoethyle Glycol/MEG) production: one is the Olefin/EO (Ethylene Oxide) Route starting from either naphtha, ethane or methanol, the licensors include Shell, SD, UCC and etc. And the other is the DMO (dimethyl oxalate) Route newly emerged in China these years, starting from syngas.
How do you remove dissolved hydrocarbons from the Meg?
In order to remove these dissolved hydrocarbons, a Rich MEG Flash Vessel will be included in the design. The Rich MEG has a salt content of 2.4 wt% and the Lean MEG specification is 85 wt% MEG on a salt-free basis. Assuming the Regenerator section of the MRU only removes water, the Lean MEG exiting the Regenerator will contain 5.82 wt% salts.
What is the raw material for Meg production?
Raw Material for MEG production is ethylene and oxygen. Ethylene is recovered from FCC off gas via Ethylene Recovery Unit and Oxygen from air through Air Separation Unit. Mono Ethylene glycol in its pure form, it is an odorless, colorless, syrupy liquid with a sweet taste.
How does a rich Meg work?
The Rich MEG is fed to the unit from the upstream facilities and letdown across the inlet level control valve. This valve reduces the pressure of the Rich MEG, allowing some of the dissolved hydrocarbons to vaporise out of the solution.
