  • Patent number: 9944844
    Abstract: Degeneration of shale caused by oxygen in aqueous drilling, fracturing and completion fluids is minimized by introducing imidazolines modified so that they will be attracted efficiently to pyrites in the shale, thereby forming a protective coating on the pyrites. Inhibiting oxidation of the pyrites sharply reduces physical degradation of the shale, and the generation of undesirable oxides, in the presence of drilling, fracturing and completion fluids carrying oxygen. The imidazoline is an ionic salt of a monocarboxylic acid.

    Abstract: The boiler anti-corrosive of the present invention contains an amine compound represented by formula (1): NH2—(CH2)m—O—(CH2)n—OH??(1) (wherein each of m and n is an integer of 1 to 3), or contains an oxygen scavenger and the amine compound represented by formula (1). The anti-corrosive is generally used in a boiler operated with a superheater or a steam turbine, or in such a boiler to which treated water is fed, and can more effectively maintain the pH of boiler water and can prevent corrosion not only of the boiler tank but also in the entire boiler system including a feed-condensate system, without adding a large amount of phosphate salt or elevating the Na/PO4 mole ratio to 3 or higher.

  • Patent number: H2287
    Abstract: A structural low carbon steel in combination with and in contact with an aqueous MDEA solvent that includes as an amine-based chemical additive. When mixed with MDEA solvent to form a MDEA solution, the MDEA-based solution in contact with carbon steel reduces the corrosion rate of low carbon structural carbon steels having a carbon content greater than about 0.18% by weight is significantly reduced when the concentrations of CO2, O2 and heat stable salts (HSS) are controlled below critical amounts. The MDEA solution, when controlling the concentrations of CO2, O2 and HSS below critical amounts, suppresses the corrosion of carbon steel having a carbon content greater than about 0.18%. A smooth surface finish further suppresses the corrosion of the low carbon structural steel. When the CO2, O2 and HSS are maintained below critical values, a low carbon structural steel having a micropolished surface finish displayed improved corrosion resistance.
