  • Patent number: 11959036
    Abstract: A component and a system for mitigating coke formation during delivery of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. Tuning the zeta potential of the contact surface allows selective attraction and/or repulsion of coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid. A method of mitigating coke formation during delivery of a hydrocarbon fluid includes tuning a zeta potential of the contact surface of the component and injecting or circulating the hydrocarbon fluid through the system such that the contact surface selectively attracts and/or repels coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid.

  • Publication number: 20230304445
    Abstract: An organometallic chemistry-based compound for preventing coke formation in a hydrocarbon fluid system. The organometallic chemistry-based compound includes a coordination complex that interrupts an autoxidative pathway of coke formation. A component and a system for mitigating coke formation during delivery or circulation of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. The contact surface is functionalized with an inhibitor ligand to form an inhibitor ligand-functionalized surface. The inhibitor ligand-functionalized surface interrupts an autoxidative pathway of coke formation.

  • Publication number: 20200080183
    Abstract: A treatment process for treating an article including a superalloy having a degraded microstructure is presented. The process includes subjecting the article to a first heat-treatment including successively heating and cooling the article between a low-end temperature and a high-end temperature and subjecting the article to a second heat-treatment at a solution annealing temperature in a range of from about 80 degrees Fahrenheit below a gamma-prime solvus temperature of the superalloy to about 80 degrees Fahrenheit above the gamma-prime solvus temperature of the superalloy after performing the first heat-treatment. The low-end temperature is in a range of from about 1000 degrees Fahrenheit to about 1800 degrees Fahrenheit and the high-end temperature is in a range of from about 1900 degrees Fahrenheit to about 2250 degrees Fahrenheit.

  • Patent number: 8268237
    Abstract: A method of coating a substrate with cryo-milled, nano-grained particles includes forming a face-centered-cubic gamma matrix comprising nickel, cobalt, chromium, tungsten and molybdenum, adding a dispersion strengthening material to the gamma matrix to form a first mixture, cryo-milling the first mixture to form a second mixture to form a nano-grained structure, and cold spraying the second mixture onto a substrate to form a coating having a nano-grained structure.
