Amine Gas treating

Amine gas treating

Amine gas treating, also known as gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkanolamines (commonly referred to simply as amines) to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases. It is a common unit process used in refineries, petrochemical plants, natural gas processing plants and other industries.

Processes within oil refineries or natural gas processing plants that remove hydrogen sulfide and/or mercaptans are commonly referred to as sweetening processes because they result in products which no longer have the sour, foul odors of mercaptans and hydrogen sulfide.

  • There are many different amines used in gas treating:
  • Monoethanolamine (MEA);
  • Diethanolamine (DEA);
  • Methyldiethanolamine (MDEA);
  • Diisopropylamine (DIPA);
  • Aminoethoxyethanol (diglycolamine)(DGA)

The most commonly used amines in industrial plants are the alkanolamines MEA, DEA, and MDEA.
