What is Triethanolamine (TEA 85%)
Triethanolamine, TEA B85 LFG 85% is a low-freeze grade version of Triethanolamine B85, a mix of triethanolamine and
diethanolamine.
The product is an aqueous blend designed to provide a lower freeze point product for those who can tolerate the presence of water in their applications. Freezing will occur at approximately -9°C versus the 18°C expected for Triethanolamine B85.

TEA Commercial Grade is a solution of Triethanolamine containing >= 85% Triethanolamine and <= 15% Diethanolamine.
TEA Commercial LFG is a solution of ~ 74% Triethanolamine, ~ 15% water and ~ 11% Diethanolamine.
TEA 99 LFG is an 85% solution of it with 15% water.
TEA 99% (a tertiary amine used to react with acidic compounds to form salts) is also
Application of Triethanolamine TEA85%
Gas sweeting:
New technologies are being implemented recently to treat highly sour natural gas with different
gas sweetening processes. As the gas acidity increases, the energy required by the process to achieve sweet gas specifications in terms of H2S and CO2concentrations will increase.
This is particularly true for gas sweetening processes that use such alkanolamine solvents as the primary amine methyl-ethanolamine (MEA), the secondary amines diethanolamine (DEA) and di-isopropanolamine (DIPA), and the tertiary amines triethanolamine (TEA) and methyl-diethanolamine (MDEA).
In textile:
Triethanolamine using in textile to make the surface softer
Dry cleaning:
It is using as water friendly additive in dry cleaning to prevenient corrosion and remove electricity from the parts.
Welding:
TEA 85% using in lubricant spray to protect the surface against the corrosion and remove acidity of moistures on.
Cosmetic:
Combination of fatic ascid with Trietanolamine with neutral and create foam in shampoo and other cosmetics.
Other application in
Adhesives, Agricultural, Cement, Photographic Chemicals, Rubber, Surfactants, Urethane Foams
