This process is also known as Amine Treating and Acid Gas Removal. A typical amine gas treating process includes an absorber and a regeneration tower. It is essential to remove sour gases such as H2S and CO2 from the natural gas stream to avoid corrosion issues with downstream processes and equipment. The most commonly used Amines include Diethanolamine (DEA), Monoethanolamine (MEA), Methyldiethanolamine (MDEA).
