1. A method for treating a liquid hydrocarbon to remove a sulfur compound therefrom, comprising: combining 1,3,5-(2H2,4H2,6H2) tripropanediamine N,N,N′,N′,N″,N″ hexamethyl triazine and the liquid hydrocarbon comprising the sulfur compound to form a reaction product of the triazine and the sulfur com
1. A method for treating a liquid hydrocarbon to remove a sulfur compound therefrom, comprising: combining 1,3,5-(2H2,4H2,6H2) tripropanediamine N,N,N′,N′,N″,N″ hexamethyl triazine and the liquid hydrocarbon comprising the sulfur compound to form a reaction product of the triazine and the sulfur compound; thencombining water with the liquid hydrocarbon and the reaction product;drawing the reaction product into the water; andseparating the liquid hydrocarbon from the water comprising the reaction product. 2. The method of claim 1, wherein the liquid hydrocarbon comprises a liquid substance selected from the group consisting of crude oil, crude petroleum, petroleum, fuel oil, gasoline, diesel oil, kerosene oil, bunker oil, compressed liquid propane, and compressed liquid butane. 3. The method of claim 1, wherein the triazine is combined with the liquid hydrocarbon at an amount within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon. 4. The method of claim 3, wherein the water is combined with the liquid hydrocarbon and the triazine at an amount within a range from about 10% to about 200% by weight of the triazine. 5. The method of claim 1, the liquid hydrocarbon comprises the sulfur compound at a concentration within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon. 6. The method of claim 5, wherein the sulfur compound comprises a compound selected from the group consisting of hydrogen sulfide, mercaptan, dialkyl disulfide, dimethyl disulfide, and derivatives thereof. 7. The method of claim 1, wherein the water containing the reaction product is separated from the liquid hydrocarbon by a decanting process. 8. The method of claim 1, wherein the water containing the reaction product is separated from the liquid hydrocarbon by a centrifuging process. 9. The method of claim 1, wherein combining the triazine and the liquid hydrocarbon comprises adding the triazine to a hydrocarbon stream containing the liquid hydrocarbon without the presence of water. 10. A method for treating a liquid hydrocarbon to remove a sulfur compound therefrom, comprising: combining at least 1,3,5-(2H2,4H2,6H2) tripropanediamine N,N,N′,N′,N″,N″ hexamethyl triazine and the liquid hydrocarbon comprising the sulfur compound to form a reaction product of the triazine and the sulfur compound, wherein the triazine is combined with the liquid hydrocarbon at an amount within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon;combining water with the liquid hydrocarbon and the reaction product;drawing the reaction product into the water; andseparating the liquid hydrocarbon from the water comprising the reaction product. 11. The method of claim 10, wherein the water is combined with the liquid hydrocarbon and the triazine at an amount within a range from about 10% to about 200% by weight of the triazine. 12. The method of claim 10, the liquid hydrocarbon comprises the sulfur compound at a concentration within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon. 13. The method of claim 12, wherein the sulfur compound comprises a compound selected from the group consisting of hydrogen sulfide, mercaptan, dialkyl disulfide, dimethyl disulfide, and derivatives thereof. 14. The method of claim 10, wherein the liquid hydrocarbon comprises a liquid substance selected from the group consisting of crude oil, crude petroleum, petroleum, fuel oil, gasoline, diesel oil, kerosene oil, bunker oil, compressed liquid propane, and compressed liquid butane. 15. The method of claim 10, wherein the water containing the reaction product is separated from the liquid hydrocarbon by a decanting process. 16. The method of claim 10, wherein the water containing the reaction product is separated from the liquid hydrocarbon by a centrifuging process. 17. The method of claim 10, wherein combining the triazine and the liquid hydrocarbon comprises adding the triazine to a hydrocarbon stream containing the liquid hydrocarbon without the presence of water. 18. A method for treating a liquid hydrocarbon to remove a sulfur compound therefrom, comprising: combining at least 1,3,5-(2H2,4H2,6H2) tripropanediamine N,N,N′,N′,N″,N″ hexamethyl triazine, water, and the liquid hydrocarbon comprising the sulfur compound to form a reaction product of the triazine and the sulfur compound, wherein the liquid hydrocarbon comprises a liquid substance selected from the group consisting of crude oil, crude petroleum, petroleum, fuel oil, gasoline, diesel oil, kerosene oil, bunker oil, compressed liquid propane, and compressed liquid butane, the sulfur compound at a concentration within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon, and the sulfur compound comprises a compound selected from the group consisting of hydrogen sulfide, mercaptan, dialkyl disulfide, dimethyl disulfide, and derivatives thereof;drawing the reaction product into the water; andseparating the liquid hydrocarbon from the water comprising the reaction product. 19. The method of claim 18, wherein the water is combined with the liquid hydrocarbon and the triazine at an amount within a range from about 10% to about 200% by weight of the triazine. 20. The method of claim 18, wherein the triazine is combined with the liquid hydrocarbon and the water at an amount within a range from about 1 ppm to about 10% by weight of the liquid hydrocarbon.
