  • Characterization of crude oil by NMR spectroscopy
    Patent number: 10684239
    Abstract: A system and a method for applying 13C or 1H NMR spectroscopy to a sample of oil in order to calculate and assign an indicative property such as cetane number, pour point, cloud point, aniline point and/or octane number of a gas oil or naphtha fraction of the crude oil.
    Type: Grant
    Filed: June 30, 2017
    Date of Patent: June 16, 2020
    Assignee: SAUDI ARABIAN OIL COMPANY
    Inventors: Omer Refa Koseoglu, Adnan Al-Hajji, Mohammed Abdullah Al-Ghamdi, Alexander Rebrov
  • High quality middle distillate production process
    Patent number: 9334451
    Abstract: A hydrocarbon feedstock is hydrocracked in a hydrocracking zone and the effluent is fractioned to recover a light fraction, a middle fraction containing aromatic compounds and a heavy fraction. The heavy fraction is recycled to the hydrocracking zone for further hydrocracking. The middle fraction is introduced to an aromatic separation zone. A product stream is recovered from the aromatic separation zone comprising a middle fraction having a reduced content of aromatic compounds as compared to the middle fraction recovered from the fractionator. Aromatics from the aromatic separation zone are recycled to the hydrocracking zone for further hydrogenation and cracking.
