Monoethylene Glycol (MEG) is originally a raw material for the production of polyester fibers and the textile industry and the production of polyethylene terephthalate resins used in the bottling industry. It is also used as a disinfectant in various industries and sectors. In addition to its antipyretic properties, it also has the ability to dehydrate. Ethylene glycol (EG) such as triethylene glycol (TEG) in the natural gas industry is used in the pre-process stage to remove water vapor from natural gas and is in fact one of the major uses of ethylene glycol in the gas industry. Another major use of ethylene glycol is heat transfer, for example in cars and computers or air conditioners or systems that need to be cooled to below freezing point. In addition, ethylene glycol is used to a lesser extent in the paint, cement and wax industries.

Mono Ethylene Glycol is the first of the three members of a homologous series of dihydroxyalcohols. MEG is produced in the Master Process by the direct hydration of ethylene oxide. Smaller amounts of diethylene glycol (DEG) and triethylene glycol (TEG) are co-produced in this process. In Shell, the MEG can also be produced by a catalytic conversion of Ethylene Oxide. This process is called OMEGA (Only MEG Advantage) and achieves a conversion efficiency of over 99% compared to around 90% for conventional processes.

Uses

MEG is by far the largest volume glycol product and is used in a variety of applications. MEG is typically commercially available in three grades: fibre, industrial and antifreeze. The markets for EG products are polyester fibres, polyethylene terephthalate (PET) plastics, coolants in automobile antifreeze, and resins. The excellent humectant (hygroscopicity) properties of EG products also make them ideal for use in fibers treatment, paper, adhesives, printing inks, leather and cellophane. Shell Chemicals does not sell to customers that use MEG in theatrical fogs or other artificial smoke generator applications; in the manufacture or preparation of foods or pharmaceuticals where glycol is not further reacted to produce a derivative product; or in aircraft de-icing applications.

 

Storage & Handling

Under the NFPA 704, mono ethylene glycol is rated as a 0 for instability, indicating that mono ethylene glycol is usually stable. Mono ethylene glycol’s vapors are heavier than air and will travel to surrounding areas. Due to its high flashpoint of 111.11°C, the chemical has a flammability rating of 1, indicating that it requires considerable preheating for ignition and combustion to occur. However, in storage, MEG should be kept away from heat, sparks, and open flames. If a fire was to occur, alcohol resistant foam or water spray should be used to fight fires with a focus on preventing the spillage from reaching water sources or sewers.
