A gas purification system including a hydrogen sulfide (H2S) absorber, a carbon dioxide (CO2) absorber, a flash tank, and a H2S concentrator. The gas purification system may also include a gas path though the H2S absorber prior to the CO2 absorber, a first solvent path sequentially through the CO2 absorber, the H2S absorber, and the H2S concentrator, and a second solvent path sequentially through the CO2 absorber, the flash tank, and the H2S concentrator, wherein the first and second solvent paths flow a common solvent.
