Product Overview
N-Methyldiethanolamine (MDEA) is a clear, colorless to pale yellow liquid with an amine-like odor. It is a tertiary amine containing two hydroxyethyl groups and one methyl group, making it a highly efficient selective solvent for acid gas treatment. MDEA is widely used in natural gas processing, petrochemical refining, and various industrial gas purification systems due to its low vapor pressure, low corrosiveness, and high selectivity for H?S over CO?.
Applications
Gas Sweetening: Used in amine gas treating units for H?S and CO? removal
Petroleum Refining: Acid gas scrubbing in hydrocracking and catalytic reforming
Chemical Intermediate: For surfactants, corrosion inhibitors, and emulsifiers
Water Treatment: pH adjustment and neutralizing agent
Polyurethane Industry: Additive in catalyst systems and foam formulations
