Monoethanolamine (MEA)

Amines, particularly Monoethanolamine (MEA), are widely used in postcombustion carbon capture for their high reactivity with CO2, also serving in natural gas sweetening. Ionic liquids, emerging in carbon capture research, are low-volatility, thermally stable salts that offer potential for efficient CO2 absorption with minimal environmental impact. While MEA remains the more cost-effective and established option, ionic liquids represent a promising, though currently costlier, alternative with benefits in stability and reduced environmental risks.
