Epoxy Oilserv Limited is a Chemical Supply company in Nigeria, We can supply any quantity of Tri-ethylene Glycol in any location in Nigeria. We are Authorized Dealers for Tri- Ethylene Glycol for most global manufacturers of Tri-ethylene Glycol.
Triethylene glycol is packed in bulk or in new ms drums (235- kg net weight). We supply also in iso containers.
Triethylene glycol TEG, or triglycol is a colorless odorless viscous liquid used as a plasticizer for vinyl. It is also used in air sanitizer products. When aerosolized it acts as a disinfectant.
Glycols are also used as liquid desiccants for natural gas and in air conditioning systems. It is an additive for hydraulic fluids and brake fluids.
Apart from its use as a raw material in the manufacture and synthesis of other products, TEG is known for its hygroscopic quality and its ability to dehumidify fluids. This liquid is miscible with water, and also soluble in ethanol, acetone, acetic acid, glycerine, pyridine and aldehydes. It is slightly soluble in diethyl ether and insoluble in oil, fat and most hydrocarbons.
TEG is used by the oil and gas industry to “dehydrate” natural gas. It may also be used to dehydrate other gases. During this process, Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas. It 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.
Uses of Triethylene Glycol
Natural gas dehydration: hygroscopic nature of teg is put to use in dehydration of natural gas. Teg is contacted counter currently with natural gas in a packed or bubble tray to remove moisture from natural gas. Teg is subsequently regenerated for reuse by stripping it of its water content. 2.
Plasticizer: Teg can be effectively used as a plastisizer for vinyls, nitro cellulose, safety glasses. Diesters of teg gives good low temperature properties and smooth film finishes.
Conditioning agent the affinity of teg for water is used advantageously in the manufacture of adhesives or pastes to eliminate shrinkage, curling and brittleness.
Uses in the Oil & Gas Industry
The main uses for tri ethylene glycol are based upon its hygroscopic quality. This means that it can absorb moisture from the air through absorption or adsorption. In the oilfield It 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.
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.
