Amine Gas Treating Systems | Schlumberger

Custom and standard amine gas sweetening systems remove CO 2 and H 2 S, resulting in gas with <2-mol% CO 2 and <4-ppm H 2 S. Efficiently removing CO 2, H 2 S, and mercaptans makes the gas suitable for transportation and use. The amine plant can be installed as a stand-alone component or as a part of an integrated processing system.
