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: 7544344Abstract: A feed gas stream containing hydrogen sulfide is subjected to a Claus reaction in a Claus furnace (16). Oxygen or oxygen-enriched air containing at least 80% by volume oxygen is supplied to the furnace (16) to support combustion of the hydrogen sulfide. Sulfur vapour is condensed out of the resultant effluent gas in a sulfur condenser (3). The sulfur depleted effluent gas is subjected to a plurality of stages of catalytic reaction of hydrogen sulfide in order to form further sulfur vapour in catalytic reactors (36, 44) and (52) with the sulfur vapour being condensed out of the gas in sulfur condensers (38, 46) and (54). The sulfur dioxide content of the resulting tail gas is reduced to hydrogen sulfide in reactor (6).Type: GrantFiled: July 13, 2004Date of Patent: June 9, 2009Assignee: The BOC Group plcInventor: Stephen Rhys Graville

Patent number: 7484372Abstract: A multi-bath apparatus and method for cooling a superconductor includes both a cooling bath comprising a first cryogen and a shield bath comprising a second cryogen. The cooling bath surrounds the superconductor, and the shield bath surrounds the cooling bath. The cooling bath is maintained at a first pressure and subcooled, while the shield bath is maintained at a second pressure and saturated. The cooling bath and the shield bath are in a thermal relationship with one another, and the first pressure is greater the second pressure. Preferably, the cryogens are liquid nitrogen, and the superconductor is a high temperature superconductor, such as a current limiter. Following a thermal disruption to the superconductor, the first pressure is restored to the cooling bath and the second pressure is restored to the shield bath in order to restore the superconductor to a superconductive state.Type: GrantFiled: March 6, 2006Date of Patent: February 3, 2009Assignee: Linde, Inc.Inventor: Ron Lee
