Abstract
Contemplated plants include an acid gas enrichment unit in which acid gas unsuitable for feeding into a Claus plant from an upstream acid gas removal unit is separated into a concentrated hydrogen sulfide stream that is fed to the Claus plant and a carbon dioxide stream that is compressed in a compressor before sequestration, further purification, and/or recycling to a gasification unit.
