摘要： Methods and systems for recovering sulfur dioxide from a Claus unit process emissions stream are provided. The method comprises the steps of generating a process emissions stream from a thermal oxidizer or other combustion device, introducing the emissions stream to an SO 2 removal system, introducing the SO 2 rich stream from the SO 2 removal system to a CO 2 removal system, and introducing an enriched SO 2 stream back to the Claus unit. The SO 2 removal system can include one or more SO 2 selective membranes. The CO 2 removal system can include one or more CO 2 selective membranes.
