Energy requirements, GHG emissions and investment costs in natural gas sweetening processes

"Currently, different technologies are being employed to remove CO2 and H2S from the natural gas. Based on chemical phenomenon, the absorption using alkanolamines is probably the most extended process for the acid gas removal. However, membrane technologies are considered as an alternative in s...
