SYSTEM FOR RECOVERING ACID GASES FROM A GAS STREAM

摘要

SYSTEM FOR RECOVERING ACID GASES FROM A GAS STREAM In one embodiment, a gas purification system is provided. The system includes a first section having a first solvent path and a first gas path. The first gas path is configured to flow a stripping gas to remove hydrogen sulfide (H2S) and carbon dioxide (C0 2) from the first solvent path in a first vessel to produce a first gas mixture. The system also includes a second section having a second solvent path. The second solvent path is configured to flow a second solvent mixture to remove H2S from the first gas mixture and CO 2 from the second solvent mixture within a second vessel. The second solvent mixture has a solvent saturated in CO 2 at a first pressure, the second vessel is operated at a second pressure, and the first and second pressures are within approximately 20% of one another. qg /J -' -. ) LLI C I o) CY I C ) --- --- -- --- - q - m IL < LLI LIi *0 C/ c/, *Li < LO cn0 cn
