Gas & Oil Treatment

(Mono- and Dimethylamine)

Alkylalkanolamines have a large use in the treatment of natural gas and oil.

Two of the largest volume alkylalkanolamines, methyldiethanolamine (MDEA) and monomethylethanolamine (NMEA), are made from the reaction of monomethylamine and ethylene oxide.

MDEA is especially important in removing acidic components in natural gas such as hydrogen sulfide, mercaptans, carbonyl sulfide, and carbon monoxide.

Dimethylammonium dimethylcarbamate, made from the reaction of dimethylamine and carbon dioxide, is used to remove sulfur compounds, olefins, and aromatic hydrocarbons from raw oil.
