The world’s top in terms of natural gas stripping from acid components is taken by amine processes. They have been used for natural gas stripping over the last few decades and still today they remain the primary type of installations accounting for roughly 70% of the total number.
The best known ethanolamines used in gas stripping processes from H2S and CO2 include monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA), diglycolamine (DHA), diisopropanolamine (DIPA), methyldiethanolamine (MDEA).
Absorption technology (amine scrubbing) is applicable in a wide range of sulfur-containing compounds and CO2 concentrations. Solutions of MEA, DEA, TEA, MDEA are used for various tasks. Other absorbents can be used as well in certain cases. With respect to reducing operating costs, such technology is capable of combining with membrane and adsorption treatment.
