Patent number: 6877725Abstract: This invention is directed to a cyclonic vapor/liquid contacting device and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall, where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone.Type: GrantFiled: July 1, 2003Date of Patent: April 12, 2005Assignee: Mobil Oil CorporationInventors: John Scott Buchanan, Berne K. Stober

Patent number: 6732881Abstract: A large, box-like polygonal tank for storing liquefied gas on land or on ground based structures (GBS) and a method of constructing the tank. The tank is comprised of an internal, truss-braced, rigid frame, having a cover on the frame for containing the stored liquid within the tank. The internal, truss-braced frame allows the interior of the tank to be contiguous throughout while compensating for the dynamic loads caused by the “sloshing” of stored liquid which, in turn, is due to the short excitation periods cause by seismic activity or the like.Type: GrantFiled: February 24, 1999Date of Patent: May 11, 2004Assignee: Mobil Oil CorporationInventor: Kailash C.

Patent number: 6713438Abstract: High performance engine oils and other liquid lubricants comprise a liquid lubricant basestock of low viscosity from 1.5 to 12 cSt (100C) with two dissolved polymer components of differing molecular weights. The basestock is preferably a single PAO or blend of PAOs with a co-basestock component which is preferably an ester or an alkylated aromatic of comparable viscosity. The lower molecular weight polymer is highly viscoelastic in character and is preferably an HVI-PAO; this component in the lubricant which provides unexpectedly high film thickness and unexpectedly good wear protection under conditions where the second, higher molecular weight polymer may lose some or all of its thickening power. The use of the highly viscoelastic low molecular weight polymer in combination with the higher molecular weight thickener enables the production of very widely cross-graded engine oils, especially oils with a low temperature grading of 0W or better.Type: GrantFiled: March 24, 1999Date of Patent: March 30, 2004Assignee: Mobil Oil CorporationInventors: David J.

Patent number: 6644406Abstract: Method and apparatus for fracturing different levels of a completion interval in a well. A workstring lowers a fracturing string which, in turn, is comprised of a base pipe which is blank except for perforated sections spaced along its length. Screen may be provided over said sections to block the flow of sand into the base pipe. An alternate flow path (e.g. shunt tubes) extends along the base pipe and has one or more outlets spaced along its length. A slurry is flowed into the annulus surrounding the fracturing string. As liquid is lost from the slurry, sand from the slurry will form bridges at said perforated sections thereby isolating portions of the annulus. Slurry then flows through the shunts tube(s) and out into the isolated portions to fracture the different levels in the completion interval.Type: GrantFiled: July 31, 2000Date of Patent: November 11, 2003Assignee: Mobil Oil CorporationInventor: Lloyd G.

Patent number: 6549879Abstract: There is disclosed herein a systematic, computationally-efficient, two-stage method for determining well locations in a 3D reservoir model while satisfying various constraints including: minimum interwell spacing, maximum well length, angular limits for deviated completions, and minimum distance from reservoir and fluid boundaries. In the first stage, the wells are placed assuming that the wells can only be vertical. In the second stage, these vertical wells are examined for optimized horizontal and deviated completions. This solution is expedient, yet systematic, and it provides a good first-pass set of well locations and configurations. The first stage solution formulates the well placement problem as a binary integer programming (BIP) problem which uses a “set-packing” approach that exploits the problem structure, strengthens the optimization formulation, and reduces the problem size. Commercial software packages are readily available for solving BIP problems.Type: GrantFiled: September 21, 1999Date of Patent: April 15, 2003Assignee: Mobil Oil CorporationInventors: Alvin S. Cullick, Sriram Vasantharajan, Mark W. Dobin
