Ethanolamine has three derivatives in Petrochemical industry, Monoethanolamine, Diethanolamine and Triethanolamine, which will be produced in a continuous process with ethylene oxide and ammonia in a PFR reactor in an industrial scale at low temperature, high pressure with more than 99% purity.
Depending on technology and feed consumption ratio and also market demands, MEA, DEA and TEA production ranges can be difference.
MDEA production process is similar to Ethanolamine process, excepting using MMA instead of ammonia.
Ethanol amines are mainly used in emulsifier productions, detergents, textile industry, gas sweetening and cement productions. The maximum usage of MEA is at detergent industry.
Other EA derivatives application, such as DEA and TEA is more than MEA which are used as a surfactant in detergents and hygiene products, gas sweetening, as cooling agents and softener in textile, rubber formulations, cleaners and waxes.
In recent decades due to the many advantages of MDEA compared to other typical amines, it has a wide application in gas sweetening because of its lower energy consumption for regeneration, with higher H2S selectivity than CO2 and less corrosion compare to typical amines. As a result, the major application of MDEA is in refinery and petrochemical industries for gas sweetening.
