New technologies are being implemented recently to treat highly sour natural gas with different gas sweetening processes. Many recent researches have focused on the mixing of different amine solvents and how their use affects both acid gas components' absorption and the energy price of the process. Usually, process simulations have been used to determine the proportionality of these different amines in the mixed solution that can meet the acid-gas-removal specification at the lowest energy requirement possible. Absorption carried out with a chemical solvent involves mass transfer with a series of exothermic reactions. The role of the chemical reaction is to speed up the mass-transfer rate as well as to provide greater solvent loading capacity at lower carbon dioxide partial pressure conditions. Solvent conversion or gas plant revamping is usually done in order to increase production or decrease plant operating cost.
