Publication number: 20100059411Abstract: A method to upgrade virgin and partially hydrogenated asphaltic residual oils by utilizing hot, high velocity combustion gas jets to rapidly atomize and heat the residual oil, maintaining the reactant temperature required to achieve the desired residual oil conversion with the minimum practical residence time, rapidly separating vapor and liquid reactants, and rapidly cooling the vapor and liquid products. The minimum required temperature and practical residence time are used for the production of deasphalted oil and asphaltene products with minimum degradation due to thermal cracking. The maximum conversion of residual oil may be substantially increased by combining a portion of the heavy oil product with the residual oil feed and partially hydrogenating this mixture.Type: ApplicationFiled: April 22, 2008Publication date: March 11, 2010Inventor: Donald Prentice Satchell, JR.

Patent number: 7594990Abstract: A process derived hydrogen donor solvent is used to increase the maximum resid conversion and conversion rate in an ebullated bed resid hydrocracker. The hydrogen donor solvent precursor is produced by hydroreforming reactions within the resid hydrocracker, recovered as the resin fraction from a solvent deasphalting unit, regenerated in a separate hydrotreater reactor, and recycled to the ebullated bed resid hydrocracker. The major advantage of this invention relative to earlier processes is that hydrogen is more efficiently transferred to the resin residual oil in the separate hydrotreater and the hydrogen donor solvent effectively retards the formation of coke precursors at higher ebullated bed resid hydrocracker operating temperatures and resid cracking rates.Type: GrantFiled: August 7, 2006Date of Patent: September 29, 2009Assignee: The BOC Group, Inc.Inventor: Donald Prentice Satchell, Jr.

Patent number: 6986874Abstract: The present invention provides a method and apparatus for producing nitrogen trifluoride. The method comprises contacting a fluorine-containing feed stream with liquid ammonium acid fluoride in a reaction zone for time and under conditions sufficient to produce nitrogen trifluoride. During the contacting step, the effective melt acidity value of the liquid ammonium acid fluoride is decreased and a reaction product stream is removed. In one embodiment, a gaseous mixture of elemental fluorine and hydrogen fluoride is contacted with a bulk liquid ammonium acid fluoride, such that the initial effective melt acidity value is greater than the melt acidity value of the bulk liquid ammonium acid fluoride in the reaction zone.Type: GrantFiled: December 14, 2000Date of Patent: January 17, 2006Assignee: The BOC Group, Inc.Inventors: Donald Prentice Satchell, Jr., Johannes Petrus le Roux

Patent number: 6910431Abstract: A method of heating a surface susceptible to oxidation or reduction includes generating a central, generally cylindrical, fuel-rich particulate jet, and a coaxial, annular, supersonic velocity, oxidant-rich jet having an auto-thermal ignition temperature greater than the temperature of the fuel-rich particulate jet, directed toward the surface to be heated, the velocity of the fuel-rich particulate jet being less than the velocity of the oxidant-rich jet; allowing the supersonic oxidant-rich jet and the fuel-rich particulate jet to coact to form a coherent particulate fuel-rich and fuel-lean jet having a central particulate fuel-rich region and a coaxial annular fuel-lean region; impinging the coherent particulate fuel-rich and fuel-lean jet upon the surface to be heated for forming a turbulent reaction zone at the surface; and controlling oxidation and reduction reactions at the turbulent reaction zone by adjusting properties of the supersonic oxidant-rich jet and/or the fuel-rich particulate jet.Type: GrantFiled: December 30, 2002Date of Patent: June 28, 2005Assignee: The BOC Group, Inc.Inventor: Donald Prentice Satchell, Jr.

Patent number: 6908601Abstract: The invention provides a method and apparatus for producing nitrogen trifluoride. The invention involves passing a working fluid through a heat engine cycle and using the mechanical energy generated by the working fluid to produce sufficient mixing intensity within a nitrogen trifluoride reactor. The method utilizes a working fluid vapor jet, such as a hydrogen fluoride vapor jet, to impart sufficient energy to the mixing zone of a reactor in order to disperse gaseous fluorine within a liquid ammonium acid fluoride melt. A gaseous reaction product stream is removed from the reactor, the reaction product stream comprising nitrogen trifluoride and a working fluid vapor. The working fluid is then separated from the nitrogen trifluoride and recycled for reuse in the process, thereby completing a heat engine cycle.Type: GrantFiled: February 8, 2002Date of Patent: June 21, 2005Assignee: The BOC Group, Inc.Inventors: Donald Prentice Satchell, Jr., Vasu R.

Patent number: 6474982Abstract: A method of heating a surface provides for a central fuel rich jet having a peripheral shroud of substantially stoichiometric combustion products and one or more fuel lean jets each having a peripheral shroud of substantially stoichiometric combustion products. The fuel lean jets are placed around the periphery of the central fuel rich jet. The fuel lean jet or jets each having shrouds of substantially stoichiometric combustion products and a careful choice of relative velocities for each results in minimizing the mixing of the fuel rich and fuel lean jets until they are at or near the surface of the material to be melted. The placement of the fuel lean jet and fuel rich jets may be reversed in applications where an oxidizing atmosphere is required at the surface to be heated.Type: GrantFiled: June 25, 2001Date of Patent: November 5, 2002Assignee: The BOC Group, Inc.Inventors: Donald Prentice Satchell, Jr., Neil George Simpson, Andrew Peter Richardson

Patent number: 6354110Abstract: In an industrial furnace used to melt glass batch or glass melt least two oxy-fuel burners are employed in the roof or side-wall of the furnace. At least one oxy-fuel burner is operated with a fuel-rich mixture and at least one other oxy-fuel burner is operated with a fuel-lean mixture. The flames are directed to intersect near the surface of the batch or the melt in order to substantially complete combustion in the vicinity of the melt thereby increasing heat transferred to the material to be melted while also reducing flame temperatures near the burner block. Axisymmetric burners are employed in the crown or roof while non-axisymmetric burners are employed in the side-wall of the furnace. Alternatively, curved burners could be employed in either location to enhance control of the respective fuel-rich and fuel-lean flame interaction.Type: GrantFiled: August 26, 1999Date of Patent: March 12, 2002Assignee: The BOC Group, Inc.Inventors: Rifat Alchalabi, Donald Prentice Satchell, Jr., Sekharipuram V.
