摘要:
Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

Implementations set forth herein relate to systems, methods, and products for preserving a blade(s) of a device, and/or other features of other apparatuses. A blade-preserving product set forth herein can be applied to surfaces of a blade of a personal hygiene product, such as an electric or non-electric razor. The blade-preserving product can include one or more disinfectants that can operate to dissociate organic matter from a surface of the blade. Additionally, the blade-preserving product can include one or more anti-oxidants, such as a carbon nano material, that can reduce a rate of oxidation occurring at the blade, and also mitigate growth of organic matter on the blade. The blade-preserving product can be included in a container with a spray nozzle, thereby allowing the blade-preserving product to be readily dispensed onto a blade before and/or after a user employs the blade.

摘要:
Inhibiting or preventing corrosion of metallic components downhole may be accomplished by introducing neutralization media into a wellbore in the proximity of downhole metallic components, where the neutralization media comprises magnesium and where the method further includes subsequently contacting the neutralization media with a potentially corrosive environment comprising at least 5 volume % water, where the water has a pH of less than 11. This contacting activates the neutralization media with the water thereby releasing magnesium ions, and the magnesium ions react with hydroxyl ions of the water to give magnesium hydroxide in an amount effective to raise the pH of the water present to be between about 8 and 12 thereby inhibiting or preventing corrosion of metallic components downhole.

The invention relates to compositions, methods and preparation of such compositions to protect metals from corrosion, especially acid corrosion. The compositions of this invention may be added to acids to protect metals from their corrosive influence, particularly at elevated temperatures. These compositions are of particular utility in the oil and gas (petroleum) industry. Also disclosed are “corrosion inhibition intensifiers” to enhance the corrosion inhibition properties of other corrosion inhibitors. Formulations which control ferric ions in acidic solutions are also disclosed. These may be combined with inhibited acids and some compositions provide both corrosion inhibition and ferric ion control.

Disclosed herein is a heat transfer fluid concentrate comprising: greater than or equal to 85 weight percent of a freezing point depressant, based on the total weight of the heat transfer fluid concentrate; 50 to 2000 ppm of lithium ions; an azole compound; an inorganic phosphate; a carboxylic acid; and an acrylate based polymer, wherein the heat transfer fluid has a pH of 7.0-9.5. The heat transfer fluid concentrate can be used to make a heat transfer fluid.

Corrosion inhibitors and methods for inhibiting or reducing corrosion of metallic surfaces are provided. A corrosion inhibitor composition may include a 3-alkylamino-2-hydroxysuccinic acid compound. A method of inhibiting corrosion of a metallic surface in an aqueous system includes the step of contacting the surface with an effective amount of a corrosion inhibitor composition. The corrosion inhibitor composition may include other components, such as zinc, and it may also exclude phosphorus.

An aqueous-based coolant for cooling and reducing corrosion potential in applications having high aluminum or nickel surface area to coolant volume ratios has a pH between 8 and 9 and includes about 35 weight % to about 65 weight % propylene glycol, about 1.0 weight % to about 4.0 weight % 2-ethylhexanoic acid, about 0.25 weight % to about 1.0 weight % sebacic acid, about 0.25 weight % to about 1.0 weight % benzoic acid and about 0.03 weight % to about 0.1 weight % molybdate oxyanion. A cooling system includes an aluminum or nickel surface and the aqueous-based coolant. A method of cooling a component surface containing aluminum or nickel includes delivering the aqueous-based coolant to the component surface and cooling the component surface with the aqueous-based coolant.
