  • Process to upgrade highly waxy crude oil by hot pressurized water
    Patent number: 10010839
    Abstract: A continuous process for upgrading highly waxy crude oil by contacting the highly waxy crude oil with supercritical water fluid to produce low pour point, high value crude oil having low sulfur, low nitrogen, and low metallic impurities for use as hydrocarbon feedstock.
    Type: Grant
    Filed: November 24, 2008
    Date of Patent: July 3, 2018
    Assignee: Saudi Arabian Oil Company
    Inventors: Ki-Hyouk Choi, Khalid Ali Al-majnouni, Ali Al-Shareef
  • Process to reduce acidity of crude oil
    Patent number: 9295957
    Abstract: A process to reduce the acidity of acidic crude oils for preventing corrosion during processing of the crude oils, including transferring through pipe lines, tanker ships and tank vehicles. Crude oil having substantial amount of organic acid, in particular, naphthenic acid compounds is contacted with supercritical water and a catalyst for deacidification. A treated crude oil product has lower amounts of organic acid compounds than the original crude oil.
    Type: Grant
