As a common product of high temperature ethylene oxidation process in the presence of silver oxide catalyst, followed by ethylene oxide hydration for the production of monoethylene glycol diethylene glycol triethylene glycol is commercially available. Other glycol compounds that may be produced in these processes include tetraethylene glycol.
Application in natural gas
Triethylene glycol is a compound that is used in many cases Used in the oil and gas industry to absorb water in natural gas. It may also be used to absorb moisture from other gases, including other oxygenated gases. For this purpose, it is necessary for the gas to dry to a certain point, because the moisture in the natural gas can cause the pipelines to freeze and cause other problems for the final consumers of natural gas. Triethylene glycol is in contact with natural gas and removes water from it. Triethylene glycol is heated to a high temperature and condensed through a system. In this process, water is lost as waste and the product is reused in the system recovers.It has been found that the product residue produced in this process contains a sufficient amount of benzene which can be classified as hazardous waste.
Application for disinfection and killing of bacteria
The ability of triethylene glycol to inactivate influenza virus (A) and fungal spores (Penicillium) has been well established. However, the extremely low toxicity of ethylene glycol, compatibility with other low-odor materials, and its antimicrobial properties indicate that it is also ideal for air disinfection purposes in small spaces.
Application to eliminate viruses
The ability of triethylene glycol to inactivate the influenza virus in the air was reported in 1943. Since the first report, the following microorganisms have been reported in articles that are inactivated in air by triethylene glycol.
- Penicillium
- chlamydophila psittaci
- Streptococcus
- pneumococcus earlier version
- Staphylococcus epidermidis
- Entamoeba coli
