Abstract
Official abstract text for this publication.
Provided is a composition capable of safely and efficiently removing a sulfur-containing compound, especially hydrogen sulfide, an —SH group-containing compound or a mixture thereof contained in a hydrocarbon, and not causing metal corrosion in devices. The composition is for removing a sulfur-containing compound in a hydrocarbon, wherein the sulfur-containing compound is hydrogen sulfide, an —SH group-containing compound or a mixture thereof, and the composition contains a dialdehyde having 6 to 16 carbon atoms and a polyalkylene glycol.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition, comprising: a dialdehyde having 6 to 16 carbon atoms and a polyalkylene glycol, wherein the composition is suitable for removing a sulfur-containing compound in a hydrocarbon, and the sulfur-containing compound is hydrogen sulfide, an —SH group-containing compound or a mixture thereof. 2. The composition according to claim 1 , wherein the dialdehyde is at least one selected from the group consisting of 3-methylglutaraldehyde, 1,9-nonanedial and 2-methyl-1,8-octanedial. 3. The composition according to claim 1 , wherein the polyalkylene glycol is at least one selected from the group consisting of polyethylene glycol, polypropylene glycol and polybutylene glycol. 4. The composition according to claim 1 , wherein the hydrocarbon is at least one selected from the group consisting of natural gas, liquefied natural gas, sour gas, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, gas oil, heavy oil, FCC slurry, asphalt and oilfield condensate. 5. A method for removing a sulfur-containing compound in a hydrocarbon, the method comprising: bringing the hydrocarbon in contact with the composition of claim 1 to remove the sulfur-containing compound in the hydrocarbon. 6. The method according to claim 5 , wherein the hydrocarbon is at least one selected from the group consisting of natural gas, liquefied natural gas, sour gas, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, gas oil, heavy oil, FCC slurry, asphalt and oilfield condensate. 7. The method according to claim 5 , wherein the dialdehyde contained in the composition is added in an amount of 0.1 to 100 mol relative to 1 mol of the sulfur-containing compound contained in the hydrocarbon. 8. The method according to claim 5 , the method comprising: bringing the hydrocarbon in contact with the composition at a temperature in a range of 0° C. to 200° C. 9. A hydrocarbon, obtained by a process comprising removing a sulfur-containing compound of hydrogen sulfide, an —SH group-containing compound or a mixture thereof in the hydrocarbon with the composition of claim 1 . 10. The composition according to claim 1 , wherein the di aldehyde is an aliphatic di aldehyde. 11. The composition according to claim 1 , wherein the dialdehyde is 3-methylglutaraldehyde. 12. The composition according to claim 1 , wherein the dialdehyde is 1,9-nonanedial. 13. The composition according to claim 1 , wherein the dialdehyde is 2-methyl-1,8-octanedial.
