In one embodiment, a gas purification system is provided. The system includes a first solvent section having a first carbon dioxide (CO2) absorber, a hydrogen sulfide (H2S) absorber, and a first solvent path that routes a first solvent through the first CO2 absorber and the H2S absorber. The gas purification system also includes a second solvent section having a second carbon dioxide (CO2) absorber and a second solvent path that flows a second solvent through the second CO2 absorber. The gas purification system has a gas path though the first and second solvent sections, wherein the first and second solvent paths are separate from one another, and the first and second solvents are different from one another.
