TEG applications
TEG has different applications in various industries. Some uses of ArChem TEG include:
- Antifreeze
- Coolants
- Chemical intermediateS
- Gas dehydration
- Heat transfer fluids
- Polyester resins
- Solvents
TEG production
Triethylene glycol is produced as a co-product of the oxidation of ethylene at high temperatures and in the presence of silver oxide as a catalyst. Then, the ethylene oxide is hydrated to produce mono, di, tri, and tetra ethylene glycols.
TEG storage
TEG should be stored and transported in stainless steel or aluminium tanks. Storage conditions of ArChem TEG are listed below:
- TEG should be stored away from incompatible materials (strong oxidizers, strong acids, and strong bases).
- TEG containers should be kept tightly closed.
- TEG should be stored in a cool, dry, and well-ventilated area, away from direct sunlight.
- The recommended storage temperature for TEG is 15-25 °C.
- TEG should be kept away from food and drink.
TEG health hazards
TEG should be kept away from heat, decomposition takes place from temperatures above 200 °C. When handling TEG, workers should wear appropriate PPE (including gloves, safety glasses, and protective clothing). Some of the necessary first-aid measures are described below:
- In case of inhalation, move the affected person to fresh air.
- In case of ingestion, rinse mouth thoroughly with water. Never give anything by mouth to an unconscious person.
- In case of skin contact, immediately flush the skin with plenty of water for at least 15 minutes.
- In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and get medical attention.
Operators should wash their hands thoroughly after handling.
