MEG (Monoethylene Glycol) — Hydrate Inhibitor Grade

Monoethylene glycol (MEG, ethylene glycol, C2H6O2, CAS 107-21-1) is the standard thermodynamic hydrate inhibitor and the base of most antifreeze and chilled-water fluids. Global Chemicals LLC supplies technical grade at 99% minimum purity, specific gravity 1.113 at 20 °C, boiling point 197 °C and freezing point −13 °C, in 200 L drums, 1,000 L IBCs, ISO tanks and bulk from stock in Muscat.

Hydrate inhibition. Natural gas and water form solid hydrates at the pressures and temperatures found in wellheads, flowlines and subsea pipelines; MEG injected continuously, typically 0.5–2 gallons per million standard cubic feet depending on water rate and the required depression, lowers the hydrate formation temperature so the line keeps flowing. Rich glycol is recovered at the receiving plant, regenerated by distillation and, where formation water brings salts, reclaimed under vacuum in a MEG regeneration and reclamation unit, then returned to the injection points. Lean glycol purity and salt content are what the unit's operators watch, which is why the certificate of analysis matters for every make-up delivery. MEG also dehydrates gas in glycol contactors where a moderate dew-point depression is enough; the MEG versus DEG guide linked on this page compares the two.

Industrial uses. A 20–30% MEG solution with corrosion inhibitors is the fluid in the chilled-water and district-cooling circuits of Oman's hotels, malls and commercial buildings, giving freeze protection in chillers and better heat transfer than brine; stronger solutions serve as heat-transfer fluids in process circuits and as de-icing fluids. Fibre-grade MEG is the monomer for polyester and PET; ask if you need that specification rather than technical grade.

Handling: MEG is combustible with a high flash point, hygroscopic and toxic if swallowed, so it stays out of food and potable circuits; store it in closed carbon-steel or stainless tanks and wear gloves and goggles. Every delivery carries a certificate of analysis with purity, water content and colour, a technical data sheet and a GHS safety data sheet.

Delivery is same day within Muscat, next day to Sohar, Salalah and Duqm, to Qalhat, Fahud and the interior gas plants by arrangement, and by road across the GCC with a certificate of origin. Request a quote with the quantity, pack type and delivery schedule.
