主权利要求
(EP3530775) 1. A method for suppressing metal corrosion attributable to a compound having an SH structure contained in a hydrocarbon, comprising adding at least one aldehyde selected from the group consisting of a monoaldehyde having 4 or more carbon atoms and a dialdehyde having 3 or more carbon atoms, to the hydrocarbon. 2. The method according to claim 1, wherein the aldehyde is a dialdehyde having 3 or more carbon atoms. 3. The method according to claim 1, wherein the aldehyde is at least one selected from the group consisting of 3-methylglutaraldehyde, 1,9-nonanedial, and 2-methyl-1,8-octanedial. 4. The method according to any one of claims 1 to 3, wherein the hydrocarbon is at least one selected from the group consisting of natural gas, liquefied natural gas (LNG), liquefied petroleum gas (LPG), sour gas, dry gas, wet gas, oilfield gas, associated gas, tail gas, dimethyl ether, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, gas oil, lubricant oil, heavy oil, A-type fuel oil, B-type fuel oil, C-type fuel oil, jet fuel oil, FCC slurry, asphalt, oil field condensate, bitumen, extra heavy oil, tar, gas to liquid (GTL), coal to liquid (CTL), asphaltene, aromatic hydrocarbon, alkylate, base oil, kerogen, coke, black oil, synthetic crude oil, reformulated gasoline, isomerized gasoline, recovered heavy oil, bottom oil, white oil, raffinate, wax, biomass fuel, biomass to liquid (BTL), biogasoline, bioethanol, bio-ETBE, and bio-diesel oil. 5. The method according to any one of claims 1 to 4, wherein the compound having an SH structure is an organic compound having a thiol group. 6. Use of at least one aldehyde selected from the group consisting of a monoaldehyde having 4 or more carbon atoms and a dialdehyde having 3 or more carbon atoms, for suppressing metal corrosion attributable to a compound having an SH structure contained in a hydrocarbon. 7. The use according to claim 6, wherein the aldehyde is a dialdehyde having 3 or more carbon atoms. 8. The use according to claim 6, wherein the aldehyde is at least one selected from the group consisting of 3-methylglutaraldehyde, 1,9-nonanedial, and 2-methyl-1,8-octanedial. 9. The use according to any one of claims 6 to 8, wherein the hydrocarbon is at least one selected from the group consisting of natural gas, liquefied natural gas (LNG), liquefied petroleum gas (LPG), sour gas, dry gas, wet gas, oilfield gas, associated gas, tail gas, dimethyl ether, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, gas oil, lubricant oil, heavy oil, A-type fuel oil, B-type fuel oil, C-type fuel oil, jet fuel oil, FCC slurry, asphalt, oil field condensate, bitumen, extra heavy oil, tar, gas to liquid (GTL), coal to liquid (CTL), asphaltene, aromatic hydrocarbon, alkylate, base oil, kerogen, coke, black oil, synthetic crude oil, reformulated gasoline, isomerized gasoline, recovered heavy oil, bottom oil, white oil, raffinate, wax, biomass fuel, biomass to liquid (BTL), biogasoline, bioethanol, bio-ETBE, and bio-diesel oil. 10. The use according to any one of claims 6 to 9, wherein the compound having an SH structure is an organic compound having a thiol group. 11. An inhibitor for metal corrosion attributable to a compound having an SH structure contained in a hydrocarbon, comprising at least one aldehyde selected from the group consisting of a monoaldehyde having 4 or more carbon atoms and a dialdehyde having 3 or more carbon atoms. 12. The inhibitor according to claim 11, wherein the aldehyde is a dialdehyde having 3 or more carbon atoms. 13. The inhibitor according to claim 11, wherein the aldehyde is at least one selected from the group consisting of 3-methylglutaraldehyde, 1,9-nonanedial, and 2-methyl-1,8-octanedial. 14. The inhibitor according to any one of claims 11 to 13, wherein the hydrocarbon is at least one selected from the group consisting of natural gas, liquefied natural gas (LNG), liquefied petroleum gas (LPG), sour gas, dry gas, wet gas, oilfield gas, associated gas, tail gas, dimethyl ether, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, gas oil, lubricant oil, heavy oil, A-type fuel oil, B-type fuel oil, C-type fuel oil, jet fuel oil, FCC slurry, asphalt, oil field condensate, bitumen, extra heavy oil, tar, gas to liquid (GTL), coal to liquid (CTL), asphaltene, aromatic hydrocarbon, alkylate, base oil, kerogen, coke, black oil, synthetic crude oil, reformulated gasoline, isomerized gasoline, recovered heavy oil, bottom oil, white oil, raffinate, wax, biomass fuel, biomass to liquid (BTL), biogasoline, bioethanol, bio-ETBE, and bio-diesel oil. 15. The inhibitor according to any one of claims 11 to 14, wherein the compound having an SH structure is an organic compound having a thiol group.
