Monoethanolamine (MEA)
Monoethanolamine (MEA), also known as 2-Aminoethanol, is an organic chemical compound with both a primary amine and a primary alcohol group. This bifunctional nature makes it an exceptionally versatile chemical intermediate. In its pure state, it is a colorless, hygroscopic liquid with a mild ammonia-like odor. MEA is most widely utilized in the energy sector for the removal of carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas and refinery process streams (amine treating). Beyond gas treatment, it serves as a crucial feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, and corrosion inhibitors. Moonarc FZCO provides premium-grade MEA focused on high purity and low color, ensuring stability and performance in sensitive industrial formulations.

Storage
Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly closed when not in use. Nitrogen blanketing is recommended to prevent oxidation and moisture absorption. For pure MEA, maintain storage temperature above 15°C to avoid crystallization. Use stainless steel (304 or 316L) or high-density polyethylene (HDPE) for storage tanks; avoid copper, brass, and bronze.
Handling
Handle in accordance with good industrial hygiene and safety practices. Wear chemical-resistant gloves (nitrile or butyl rubber), safety goggles, and face shields. Ensure adequate ventilation. Do not breathe vapors or mists. Wash thoroughly after handling. Use explosion-proof equipment where applicable.
