What is Triethylene Glycol used for?

Oil & Gas Industry
The main uses for triethylene glycol are based upon its hygroscopic quality.
This means that it can absorb moisture from the air through absorption or adsorption.
Triethylene glycol is used as a dehydrating agent for natural gas pipelines where it removes the water from the gas before being condensed.
The triethylene glycol can then be continually reused, although the by-product of benzene needs to be disposed of carefully.
This process is useful as it prevents the gas from freezing making the gas easier to transport and manage for end consumers.

Mild Disinfectant
Triethylene glycol can also be used as a mild disinfectant.
Due to its low toxicity, antimicrobial properties, and low odour, it is commonly used for air disinfection in occupied areas where more aggressive disinfectants cannot be used.
Due to these disinfectant properties and the dehydrating properties, it is an ideal dehumidifying agent in air-conditioning units.

Preparation
Triethylene glycol is prepared commercially as a co-product of the oxidation of ethylene at high temperature in the presence of silver oxide catalyst, followed by hydration of ethylene oxide to yield mono(one)-, di(two)-, tri(three)- and tetraethylene glycols.

Applications:

Triethylene glycol is used by the oil and gas industry to "dehydrate" natural gas.
Triethylene glycol may also be used to dehydrate other gases, including CO2, H2S, and other oxygenated gases.
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.
Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas.
Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system.
The waste Triethylene glycol produced by this process has been found to contain enough benzene to be classified as hazardous waste (benzene concentration greater than 0.5 mg/L).

Triethylene glycol is well established as a relatively mild disinfectant toward a variety of bacteria, influenza A viruses and spores of Penicillium notatum fungi. However, its exceptionally low toxicity, broad materials compatibility, and low odor combined with its antimicrobial properties indicates that it approaches the ideal for air disinfection purposes in occupied spaces.
Much of the scientific work with triethylene glycol was done in the 1940s and 1950s, however that work has ably demonstrated the antimicrobial activity against airborne, solution suspension, and surface bound microbes.
The ability of triethylene glycol to inactivate Streptococcus pneumoniae (original citation: pneumococcus Type I), Streptococcus pyogenes (original citation: Beta hemolytic streptococcus group A) and Influenza A virus in the air was first reported in 1943.
Since the first report the following microorganisms have been reported in the literature to be inactivated in the air: Penicillium notatum spores, Chlamydophila psittaci (original citation: meningopneumonitis virus strain Cal 10 and psittacosis virus strain 6BC), Group C streptococcus, type 1 pneumococcus, Staphylococcus albus, Escherichia coli, and Serratia marcescens Bizio (ATCC 274).
Solutions of triethylene glycol are known to be antimicrobial toward suspensions of Penicillium notatum spores, Streptococcus pyogenes (original citation: Beta hemolytic streptococcus Group A ), Streptococcus pneumoniae (original citation: pneumococcus Type I), Streptococcus viridans, and Mycobacterium bovis (original citation: tubercle bacilli Ravenel bovine-type).
Further, the inactivation of H1N1 influenza A virus on surfaces has been demonstrated.
The latter investigation suggests that triethylene glycol may prove to be a potent weapon against future influenza epidemics and pandemics.
However, at least some viruses, including Pseudomonas phage phi6 become more infectious when treated with triethylene glycol.
