Abstract: A method and system for liquid sulfur degassing is disclosed. The method and system generally involve degassing liquid sulfur in a degassing vessel, and the level of the liquid sulfur in the degassing vessel is controlled in the degassing vessel by determining the level of liquid sulfur in the degassing vessel.

Abstract: 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.
