Abstract
Disclosed herein are systems and methods for treating carbon dioxide in an environmentally effective manner. Systems and methods include providing a carbon dioxide enriched stream having CO2 and at least one oxidizable sulfur compound and passing at least some of the carbon dioxide enriched stream to carbon dioxide storage, wherein the method further comprises passing at least some of the carbon dioxide enriched stream to selective sulfur removal during a period of system upset. Selective sulfur removal may comprise treatment with an solid or liquid capable of oxidizing the oxidizable sulfur compound.
Claims10
A method for treating carbon dioxide, comprising:
- providing a carbon dioxide enriched stream comprising carbon dioxide and at least one oxidizable sulfur compound selected from hydrogen sulfide, carbonyl sulfide, mercaptan, dialkyl sulfide or dialkyl disulfide, wherein the carbon dioxide enriched stream comprises at least about 50 mol % CO2;
- and
- passing at least some of the carbon dioxide enriched stream to carbon dioxide storage;
- wherein the method further comprises passing at least some of the carbon dioxide enriched stream to selective sulfur removal during a period of system upset, and a cleaned CO2-rich stream is recovered from the selective sulfur removal, and the cleaned CO2-rich stream is subsequently vented, channeled to a turbine, recycled to a gasifier, and/or admixed with a combustible material and flared.
