Monoethanolamine (MEA)

Categories:

Monoethanolamine (MEA) is a clear, colourless, viscous organic compound that functions as both an amine and an alcohol. It is widely used as an industrial chemical in gas treatment, surfactant production, pH control, detergents, and chemical synthesis. Due to its strong alkaline nature and reactivity, MEA is a key intermediate in the manufacture of emulsifiers, corrosion inhibitors, and specialty chemicals. It plays a critical role in carbon dioxide (CO₂) and hydrogen sulfide (H₂S) removal in gas processing systems.
