Definitions

  • the present invention relates to a composition for removing iron sulfide and a method for removing iron sulfide, which includes using the same.
  • Hydrogen sulfide that often exists in hydrocarbons, such as fossil fuels and refined petroleum products, for example, natural gas, liquefied natural gas, sour gas, crude oil, naphtha, heavy aromatic naphtha, gasoline, kerosene, diesel oil, light oil, heavy oil, FCC slurry, asphalt, and oil field concentrates, corrodes iron which is used in excavation facilities, etc., to cause generation of iron sulfide.
  • the iron sulfide is accumulated as a deposit within production facilities of fossil fuels and refined petroleum products, to lower operational efficiency of instruments in heat exchanger, cooling tower, reactor, transmission pipeline, furnace, etc., or disturb precise measurement for facility maintenance, and therefore, it is desired to remove this.
  • the acrolein is a compound which is strongly toxic and whose concentration is strictly regulated from the viewpoint of occupational safety and from the viewpoint of environmental safety, so that it involves such a problem that attention is required for handling.
  • the acrolein is problematic from the viewpoint that it is extremely easily polymerized and lacks in thermal stability and also from the viewpoint that it lacks in pH stability, so that its abundance gradually decreases depending upon the pH of the environment to be used.
  • NPL 1 SPE Annual Technical Conference and Exhibition SPE 146080, 2011; http://dx.doi.org/10.2118/146080-MS

  • composition of the present invention contains the aldehyde (1), an excellent removal performance of iron sulfide is exhibited.
  • the composition of the present invention has such an advantage that it is extremely low in toxicity and high in thermal stability and pH stability. Though the reasons for this are not elucidated yet, it may be considered as one of factors that since the aldehyde (1) has at least one of an alkyl group, an alkenyl group, and an aryl group at the ⁇ -position thereof, an addition reaction to the ⁇ -position of a bulky molecule, such as a biomolecule and a propagating chain, is hard to occur as compared with acrolein not having a substituent at the ⁇ -position thereof.
  • the aldehyde (1) comes to bond to hydrogen sulfide that is existent in an equilibrium state with iron sulfide to thereby remove hydrogen sulfide, dissolution of iron sulfide is promoted, and as a result, the iron sulfide is removed; and while the aldehyde (1) has a substituent at the ⁇ -position thereof, an attack from hydrogen sulfide that is in general a small molecule is not hindered so much, whereby the removal performance of iron sulfide is kept.
  • composition of the present invention includes the aldehyde (1) as an active ingredient.

  • a methyl group, an ethyl group, or a n-propyl group is preferred, a methyl group or an ethyl group is more preferred, and a methyl group is still more preferred.
  • the alkenyl group having 2 to 10 carbon atoms, which R 1 to R 3 each independently represent, may be linear, branched, or cyclic, and examples thereof include a vinyl group, an allyl group, a 1-penten-1-yl group, a 4-methyl-3-penten-1-yl group, a 4-penten-1-yl group, a 1-hexen-1-yl group, a 1-octen-1-yl group, and a 1-decen-1-yl group.
  • an alkenyl group having 1 to 8 carbon atoms is preferred, and an alkenyl group having 1 to 6 carbon atoms is more preferred.

Above all, an aryl group having 6 to 10 carbon atoms is preferred.
  • examples of the alkylene group include an ethylene group, a n-propylene group, a n-butylene group, a n-pentylene group, a hexylene group, a 2-methylethylene group, a 1,2-dimethylethylene group, a 2-methyl-n-propylene group, a 2,2-dimethyl-n-propylene group, and a 3-methyl-n-pentylene group.
  • R 1 to R 3 are each independently a hydrogen atom or an alkyl group having 1 to 5 carbon atoms.
  • R 1 and R 2 are a methyl group, and it is still more preferred that both R 1 and R 2 are a methyl group.
  • R 3 is a hydrogen atom.
  • aldehyde (1) examples include 2-butenal, 2-pentenal, 2-hexenal, 2-heptenal, 2-octenal, 2-nonenal, 2-decenal, 2-undecenal, 2-dodecenal, 2-tridecenal, 4-methyl-2-pentenal, 4-methyl-2-hexenal, 5-methyl-2-hexenal, 4,4-dimethyl-2-pentenal, 6-mehyl-2-heptenal, 4-ethyl-2-hexenal, 2-methyl-2-butenal, 2-methyl-2-pentenal, 2-methyl-2-hexenal, 2-methyl-2-heptenal, 2-methyl-2-octenal, 4-methyl-2-propyl-2-hexenal, 2,4-dimethyl-2-pentenal, 2,4-dimethyl-2-hexenal, 2,4-dimethyl-2-heptenal, 2,5-dimethyl-2-hexenal, 2,6-dimethyl-2-heptenal,
