Abstract
A method for introducing inhibitor into a fluid to be treated, the method including forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1; and using at least a portion of the dispersion to inhibit corrosion.
Claims13
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion corn rises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1, wherein the droplets, particles, or gas bubbles have a mean diameter of less than 5 μm, and wherein the dispersion is formed in a high shear device;
- and
- using at least a portion of the dispersion to inhibit corrosion,
- wherein the fluid to be treated comprises boiler feedwater or a transport stream comprising hydrocarbons.
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1;
- and
- using at least a portion of the dispersion to inhibit corrosion,
- wherein using at least a portion of the dispersion to inhibit corrosion comprises injecting the dispersion into a gas well, and wherein the dispersion is formed from a liquid or solid inhibitor.
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- forming a dispersion comprising bubbles of a gaseous inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1;
- and
- using at least a portion of the dispersion to inhibit corrosion.
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1, and
- using at least a portion of the dispersion to inhibit corrosion,
- wherein using at least a portion of the dispersion to inhibit corrosion comprises injecting the dispersion into a geothermal system, and wherein the carrier comprises at least a portion of the fluid to be treated.
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s−1;
- and
- using at least a portion of the dispersion to inhibit corrosion,
- wherein forming the dispersion comprises contacting the inhibitor and the carrier in a high shear device, wherein the high shear device comprises at least one rotor, and wherein the at least one rotor is rotated at a tip speed of at least 22.9 m/s (4,500 ft/min) during forming of the dispersion, wherein the carrier is LPG, and wherein the high shear device produces a local pressure of at least about 1034.2 MPa (150,000 psi) at the tip of the at least one rotor.
A method for introducing inhibitor into a fluid to be treated, the method comprising:
- processing a fluid mixture comprising inhibitor and a carrier fluid in a high shear device to produce a dispersion of inhibitor in the carrier fluid;
- and
- using the dispersion to inhibit a component selected from the group consisting of ice, scale hydrates, acidic chemicals, and combinations thereof, via introducing the dispersion into a boiler,
- wherein using the dispersion comprises treating a surface of a vessel or a flow line of the boiler, wherein the dispersion comprises particles, droplets, or gas bubbles of inhibitor having an average diameter of the droplets, particles, or gas bubbles less than about 5 μm.
