Amine Gas Treating: H2S and CO2 Removal



Natural gas contains a significant amount of hydrogen sulfide (H2S) and carbon dioxide (CO2). Natural gas is also referred to as sour gas because of its strong odor, caused by the sulfur content. These sulfur compounds render it extremely harmful, even lethal, to breathe. Natural gas can also be extremely corrosive. Carbon dioxide must be removed before the gas can be transformed into liquid form (liquefaction LNG) for transportation. Liquefaction happens at an extremely low temperature (-161 °C or -258 °F) at which carbon dioxide can freeze and consequently block pipelines.
