WHAT IS MONOETHYLENE GLYCOL – MEG ?

Monoethylene Glycol (MEG) or Ethylene glycol in its pure form, is an odorless, colorless, syrupy liquid with a sweet taste. Ethylene glycol is produced from ethylene, via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. Under these conditions, ethylene glycol yields of 90% can be achieved. The major by-products are the ethylene glycol oligomers diethylene glycol, triethylene glycol, and tetraethylene glycol. It is commonly known as EG and is a colorless liquid with a sweet, odorless taste.One of the most important properties of this compound is its heat transfer properties. Some systems that require low, high or constant temperatures usually use these materials. Materials have heat transfer properties of liquids or gases that are generally divided into 3 categories.

APPLICATIONS OF MONOETHYLENE GLYCOL 

The most important applications of monoethylene glycol are primarily used in antifreeze formulations (50%) and secondly as a raw material in the production of polyesters such as polyethylene terephthalate (PET) (40%).

1- As a cooling agent and heat transfer: the most common use of ethylene glycol is as an intermediary for heat transfer by convection in cars and cooling computers. meg chemicals are also commonly used as coolants for chilled water air conditioning systems; Where either chillers or air conditioners are placed outside the building or water must be cooled to a temperature below freezing.

In geothermal energy based heating/cooling systems, ethylene glycol is the liquid that transfers heat using a geothermal heat pump. Monoethylene glycol generally derives energy from a source (lake, ocean, water well).

The heat capacity of pure ethylene glycol is half of the heat capacity of water. Therefore, MEG reduces the specific heat capacity of water mixtures compared to pure water while providing protection against freezing and increasing the boiling point.

Mixing monoethylene glycol with water provides additional benefits for cooling and antifreeze solutions; These advantages include preventing corrosion and acid degradation as well as preventing the growth of microbes and fungi.

2- As an antifreeze: MEG in pure monoethylene glycol antifreeze freezes at about −12°C (10.4°F), but when mixed with water, the mixture freezes at lower temperatures. For example, a mixture of 60% ethylene glycol and 40% water freezes at -45°C. Diethylene glycol behaves similarly.

Depending on whether the antifreeze is ethylene glycol or propylene glycol, there is a difference in their mixing ratio. For monoethylene glycol, mixing ratios are typically 70/30 and 65/35, while propylene glycol mixing ratios are typically 35/65 and 40/60. It is important that this mixture is an excellent antifreeze solution at the lowest operating temperature.

Monoethylene glycol is used as an antifreeze liquid for car and airplane windshields, as an antifreeze in car engines.

The use of ethylene glycol not only lowers the freezing point of aqueous mixtures, but also increases their boiling point. This results in expanding the operating temperature range of fluids for heat transfer.

3- As a precursor of polymers: in the plastic industry, monoethylene glycol is an important precursor for the preparation of polyester fibers and resins. Polyethylene terephthalate, which is used in making plastic soft drink bottles, is made from ethylene glycol.

4- Other applications

Abzda agent: Ethylene glycol is used in the natural gas industry to remove water vapor mixed with natural gas before processing.

Hydrate inhibition: Ethylene glycol is a very practical and useful drying agent due to its high boiling point and its affinity for water. MEG is widely used to prevent the formation of natural gas clathrates (various hydrated forms in methane) in long multiphase pipelines that transport natural gas from gas fields over long distances to a gas processing facility. Ethylene glycol can be recovered from natural gas and reused as an inhibitor after treatment that removes water and inorganic salts. Natural gas loses a significant amount of its water volume by ethylene glycol. In this application, ethylene glycol flows down from the top of the tower and encounters a mixture of water vapor and hydrocarbon gases. Dry gas exits from the top of the tower. Glycol and water are separated and glycol is recycled. Instead of removing water, monoethylene glycol can be used to reduce the temperature in the formation of hydrates. The purity of MEG used for hydrate inhibition is typically around 80%, while the purity of triethylene glycol used for this purpose is typically 95 to over 99%.

Minor but important uses:

• Other very minor uses of monoethylene glycol include the production of capacitors, use as an intermediate chemical in the production of 1,4-dioxane, use as an additive to prevent corrosion in cooling systems for personal computers.
• Ethylene glycol is also used in making some vaccines.
• It is used as a minor ingredient (1-2%) in shoe polish and also in some inks and paints.
• Ethylene glycol is used in some cases as an agent to remove decay and treat wood to prevent the growth of fungi. In a few cases, it has been used to treat partially decayed wooden objects for display in museums. This is just one useful solution that has been successful in dealing with wooden boat rot and is relatively inexpensive.
• Monoethylene glycol may be a minor ingredient in screen cleaning solutions, along with the main ingredient isopropyl alcohol.
• Ethylene glycol is commonly used as a preservative for biological specimens, especially in high schools or colleges, when dissecting tissues or organs, as a safer alternative to formaldehyde.
• Also, MEG is used as a part of water hydraulic fluid to control subsea oil and gas production equipment.
• Ethylene glycol can be used as a protecting group in organic synthesis to protect carbonyl compounds such as ketones and aldehydes.

MEG FOR E&E

MEG is a high purity process chemical use as medium for suspending conductive salt in electrolytic capacitors or solvent for rinse semiconductor. The global monoethylene glycol market is expected to witness significant growth over the forecast period on account of its widespread applications in numerous end-use industries including consumer goods, construction, automotive, pharmaceutical, textiles, and chemical processing. Increasing demand for polyester fiber from the global textile industry has triggered increased production of monoethylene glycol (MEG) which is expected to be a major driver for market growth. Increasing application scope of polyethylene terephthalate (PET) in numerous consumer good products such as food containers and bottles is anticipated to propel demand for MEG over the next seven years.  Rapid urbanization and changing lifestyle of consumers, particularly in emerging economies including China, India, Brazil and Mexico have been driving the packaging industry which in turn is anticipated to provide impetus to MEG market over the forecast period. Owing to its superior chemical properties including high viscosity, low freezing point, and high boiling point, MEG is widely employed in the manufacture of coolants and deicing materials. Burgeoning automotive sector coupled with aircraft manufacturing units in emerging economies of Asia Pacific and Latin America is further likely to fuel market demand. However, threat of substitutes from higher glycol byproducts such as DEG and TEG coupled with high cost involved in refining of ethylene glycols is challenge MEG market over the next seven years. Potential health hazards of MEG on account of its toxic nature are further anticipated to pose a credible threat to market.

MEG IS WIDELY USED BY THE OIL AND GAS MARKETS

In wellheads and pipelines to prevent hydrate formation at pipeline conditions. In offshore deepwater gas production facilities, where the exposure to lower temperatures in subsea pipelines is common, Monoethylene Glycol-MEG is used for hydrate inhibition. Hydrate inhibition is achieved by injecting Monoethylene Glycol (MEG) to decrease the hydrate formation temperature below the operating temperature, thereby preventing hydrate blockage of the pipeline. During the gas production process, the lean glycol mixes with the produced water from the formation. The production fluid containing natural gas with associated condensate, produced water, and the injected MEG enters the production facility, where the fluids undergo phase separation. The produced fluids pass through a slug catcher and are then flashed in a three-phase production separator to separate gas, hydrocarbon liquids, and the produced water and MEG mixture, commonly known as rich MEG. The produced gas and hydrocarbon liquids are routed onshore for sales and further processing.

PRODUCTION METHOD OF MONOETHYLENE GLYCOL

Monoethylene glycol is produced from ethylene by an intermediary called ethylene oxide. In this process, EO and water will react together and ethylene glycols including MEG, DEG and TEG (triethylene glycol) will be produced, one of the interesting points about this reaction is that the reaction can be done in environments with different pH, but it is recommended to perform a higher efficiency in acidic or neutral environment with excess amounts of water. Monoethylene Glycol is produced using an intermediate called Ethylene Oxide. During this process, Ethylene Oxide reacts with water to produce MEG based on the following reaction:

C2H4O + H2O → HOCH2CH2OH

The mentioned chemical reaction can take place in environments with different pHs. More specifically, this reaction may occur in the presence of acidic or alkaline catalysts or in neutral acidity at high temperatures; while the highest yield of ethylene glycol occurs at acidic or neutral pH in the presence of large amounts of water. The major by-products of Ethylene glycol are Diethylene Glycol oligomers, Triethylene Glycol and Tetraethylene Glycol.

On the other hand, another method for producing Monoethylene Glycol has been introduced by Chinese in recent years. This new method of producing Monoethylene Glycol-MEG , utilizes gas synthesis which is produced from coal. In this process, firstly, carbon monoxide (isolated from gas synthesis) is produced by oxidation reaction with Methyl Nitrite, Dimethyl Oxalate, and then converted to Monoethylene Glycol-MEG . Methanol is recycled in the process to be used to produce more Methyl Nitrite. The only raw material for the production of MEG is synthesis gas and water.
