Patent number: 8617383Abstract: An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or with only a high pressure separation so that the dewaxing still occurs under sour conditions. Various combinations of hydrotreating, catalytic dewaxing, hydrocracking, and hydrofinishing can be used to produce fuel products and lubricant base oil products.Type: GrantFiled: June 27, 2011Date of Patent: December 31, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Krista Marie Prentice, Michel Daage, Ajit Bhaskar Dandekar, Christopher Gordon Oliveri, Rohit Vijay, Stephen J. McCarthy, Wenyih F. Lai, Bradley R. Fingland

Patent number: 8535518Abstract: A petroleum feedstock upgrading method is provided. The method includes supplying a mixed stream that includes hydrocarbon feedstock and water to a hydrothermal reactor where the mixed stream is maintained at a temperature and pressure greater than the critical temperatures and pressure of water in the absence of catalyst for a residence time sufficient to convert the mixed stream into a modified stream having an increased concentration of lighter hydrocarbons and/or concentration of sulfur containing compounds. The modified stream is then supplied to an adsorptive reaction stage charged with a solid adsorbent operable to remove at least a portion of the sulfur present to produce a trimmed stream. The trimmed stream is then separated into a gas and a liquid streams, and the liquid stream is separated into a water stream and an upgraded hydrocarbon product stream.Type: GrantFiled: January 19, 2011Date of Patent: September 17, 2013Assignee: Saudi Arabian Oil CompanyInventors: Ki-Hyouk Choi, Mohammad F.

Patent number: 8524074Abstract: The invention is directed towards a method of removing mercury bearing species from a hydrocarbon containing fluid. The method comprises the steps of: i) adding dithiocarbamate polymer to the fluid in an amount such that the number of mercury bonding sites on the polymer exceeds the amount of mercury atoms by at least 10% and ii) removing the mercury bearing dithiocarbamate polymer with a water/oil separation device. The invention relies upon an unexpected reversal in the solubility of dithiocarbamate polymer at very high concentrations. Because of the high solubility the polymer remains within the water phase of the hydrocarbon fluid and can be removed without the need for cumbersome precipitation methods and complicated solid liquid separation devices. As a result, the invention allows mercury contaminated crude oil to be easily rid of its mercury with easy to use equipment already present in a typical oil refinery.Type: GrantFiled: August 17, 2011Date of Patent: September 3, 2013Assignee: Nalco CompanyInventors: Michael L. Braden, Samuel A. Lordo
