  • Synergistic effects among mercaptan scavengers
    Patent number: 11802246
    Abstract: A combination of at least one basic compound, such as potassium hydroxide, together with at least one aldehyde donor can synergistically scavenge mercaptans from organic fluids, such as hydrocarbons, where “synergistically effective” is defined as the amount of mercaptans scavenged is greater as compared with a combination where either the basic compound or the reaction product is absent, used in the same total amount.
    Type: Grant

    Date of Patent: October 31, 2023
    Assignee: BAKER HUGHES OILFIELD OPERATIONS LLC
    Inventors: Peng Jin, Zhengwei Liu, Jerry J. Weers, Sunder Ramchandran, Jagrut Jani, Scott Lehrer, Johnathon Brooks

  • Amine and membrane separation treatment of liquid hydrocarbon media
    Publication number: 20070049777
    Abstract: Carbonyl species contamination of liquid hydrocarbon media and corrosion of metal surfaces in contact with such media are inhibited. A high boiling point primary or secondary amine is added to the desired liquid hydrocarbon medium, and in one exemplary embodiment, the medium is then brought into contact with a separatory membrane such as a nanofiltration membrane. The permeate from the membrane is a highly purified hydrocarbon stream.

  • High temperature corrosion inhibitor
    Publication number: 20060091044
    Abstract: A process for the inhibition of corrosion caused by naphthenic acid during the elevated temperature processing of crude oil or the high temperature distillates derived therefrom by use of a treatment comprising (I) tetra functional substituted aromatic compounds and (II) esters or anhydrides of trimellitic acid.
