Abstract
Methods and systems for producing sulfuric acid and/or sulfur trioxide, which may include contacting a first stream that includes oxygen and a second stream that includes sulfur to produce a third stream that includes sulfur dioxide, and subjecting the third stream to an oxidation reaction to produce a fourth stream that includes sulfur trioxide. The contacting of the first and second streams may include contacting a molar amount of oxygen that exceeds a molar amount of sulfur.
Claims30
A method of producing a product, the method comprising:
- providing a first stream comprising oxygen;
- providing a second stream comprising sulfur;
- contacting the first stream and the second stream to produce a third stream, the third stream comprising sulfur dioxide, wherein the contacting of the first stream and the second stream comprises contacting a molar amount of oxygen that exceeds a molar amount of sulfur, wherein the molar amount of oxygen exceeds the molar amount of sulfur by at least 100%;
- and
- subjecting the third stream to an oxidation reaction to produce a fourth stream, the fourth stream comprising sulfur trioxide;
- wherein the contacting of the first stream and the second stream comprises combusting the first stream and the second stream, and the combusting of the first stream and the second stream comprises a single stage combustion.
A method of producing a product, the method comprising:
- providing a first stream comprising oxygen;
- providing a second stream comprising sulfur;
- contacting the first stream and the second stream to produce a third stream, the third stream comprising sulfur dioxide, wherein the contacting of the first stream and the second stream comprises contacting a molar amount of oxygen that exceeds a molar amount of sulfur, wherein the molar amount of oxygen exceeds the molar amount of sulfur by at least 30%;
- and
- subjecting the third stream to an oxidation reaction to produce a fourth stream, the fourth stream comprising sulfur trioxide, sulfuric acid, oleum, or a combination thereof.
