As many of the clinical signs and symptoms of ethylene glycol poisoning are nonspecific and occur in many poisonings; the diagnosis is often difficult. [24] It is most reliably diagnosed by the measurement of the blood ethylene glycol concentration. Ethylene glycol in biological fluids can be determined by gas chromatography. [25]
Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economical means of water removal from these streams. [1] Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol ...
TEG is used by the oil and gas industry to "dehydrate" natural gas.It may also be used to dehydrate other gases, including CO 2, H 2 S, and other oxygenated gases. [2] It is necessary to dry natural gas to a certain point, as humidity in natural gas can cause pipelines to freeze, and create other problems for end users of the natural gas.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
Ethylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic ...
Most types of ethylene glycol antifreeze contain a few percent of diethylene glycol, present as a by-product of ethylene glycol production. DEG is an important industrial desiccant . It absorb water from natural gas , minimizing the formation of methane hydrates , which can block pipes.
WHO testing on June 27, 2023, revealed alarming levels of diethylene glycol in Naturcold, reaching as high as 28.6% – over 200 times the acceptable limit, which should not exceed 0.1%. This highly toxic solvent, normally used in air-conditioners and fridges, can lead to severe symptoms, including acute kidney injury and even death if ingested.
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
