Processes and systems for oxygen-enhanced Claus carbon dioxide recovery are disclosed. Oxygen is fed to a sulfur recovery unit instead of air. The tail gas is fed to a tail gas treatment unit which produces a treated tail gas, and the treated tail gas is processed in a carbon dioxide recovery unit to produce a carbon dioxide product. A method for retrofitting an existing sulfur recovery unit and tail gas treatment unit so as to recover the carbon dioxide product is also disclosed.

Oxygen-enhanced Claus carbon dioxide recovery

Elemental sulfur carrying capacity of a hydrocarbonaceous solvent is improved by first loading the solvent with sulfur and subsequent hydrotreatment under conditions that convert at least some of the elemental sulfur in the sulfur loaded solvent to hydrogen sulfide while preserving at least 95% of the monoaromatic and polyaromatic components in the solvent.
