gassweetening
Gas sweetening is a process used in the oil and gas industry to remove acidic gases, primarily hydrogen sulfide (H₂S) and carbon dioxide (CO₂), from natural gas and synthesis gas. These acidic components are often referred to as "sour" gases. The presence of H₂S is particularly problematic due to its corrosive nature, toxicity, and its ability to form explosive metal sulfides. CO₂, while less acutely toxic, reduces the heating value of natural gas and can also contribute to corrosion, especially in the presence of water.
The primary method for gas sweetening involves the use of chemical absorbents. Amine-based solvents are the
The rich amine solution, now containing the absorbed acidic gases, is then sent to a regenerator. Here,
