Multiple solvent gas purification and recovery system

摘要

A gas purification system (108) is provided. The system (108) includes a first solvent section (146) having a first carbon dioxide (CO 2 ) absorber, a hydrogen sulfide (H 2 S) absorber, and a first solvent path that routes a first solvent through the first CO 2 absorber and the H 2 S absorber. The gas purification system (108) also includes a second solvent section (148) having a second carbon dioxide (CO 2 ) absorber and a second solvent path that flows a second solvent through the second CO 2 absorber. The gas purification system (108) has a gas path (109) though the first (146) and second solvent sections (148), wherein the first and second solvent paths are separate from one another, and the first and second solvents are different from one another.
