摘要
(US8945496) 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.

主权利要求
(US8945496) What is claimed as new and desired to be protected by Letters Patent of the United States is: 1.  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. 2. The method according to claim 1, wherein the carbon dioxide enriched stream comprises hydrogen sulfide in an amount of from about 0.1 mol % H2S to about 2 mol % H2S. 3. The method according to claim 1, wherein carbon dioxide storage comprises a carbon dioxide sink selected from one or more of: carbon dioxide pipeline, enhanced oil recovery system employing carbon dioxide, CO2 storage tank, saline aquifer CO2 storage, undersea CO2 storage, subsea CO2 storage, well, mine, and cave; and wherein system upset comprises condition where the carbon dioxide sink has insufficient capacity to accept CO2. 4. The method according to claim 1, further comprising passing the carbon dioxide enriched stream to a compression system prior to passing at least some of the carbon dioxide enriched stream to carbon dioxide storage, and wherein system upset comprises condition where the compression system has insufficient capacity to compress the carbon dioxide enriched stream. 5. The method according to claim 1, wherein system upset comprises condition selected from one or more of: insufficiency of an acid gas removal unit, plant startup, and plant shutdown. 6. The method according to claim 1, wherein selective sulfur removal comprises one or more selected from selective physical sulfur removal and selective chemical sulfur removal. 7. The method according to claim 1, wherein selective sulfur removal comprises oxidation of the at least one oxidizable sulfur compound by an oxidative liquid or an oxidative solid. 8. The method according to claim 7, wherein selective sulfur removal comprises oxidation of the at least one oxidizable sulfur compound by an oxidative liquid, wherein the oxidative liquid comprises an aqueous solution of a compound of one or more metal selected from iron, copper, manganese, vanadium, and cobalt. 9. The method according to claim 1, wherein the carbon dioxide enriched stream is derived from a syngas. 10. The method according to claim 9, further comprising gasifying a carbonaceous feedstock in a gasifier to form the syngas.
