Publication number: 20140165928Abstract: Systems and methods relate to vaporizing water into steam, which may be utilized in applications such as bitumen production. The methods rely on indirect boiling of the water by contact with a substance such as solid particulate heated to a temperature sufficient to vaporize the water. Heating of the solid particulate may utilize pressure isolated heat exchanger units or a hot gas recirculation circuit at a pressure corresponding to that desired for the steam. Further, the water may form part of a mixture that contacts the solid particulate and includes a solvent for the bitumen in order to limit vaporization energy requirements and facilitate the production.Type: ApplicationFiled: December 3, 2013Publication date: June 19, 2014Applicant: CONOCOPHILLIPS COMPANYInventors: David W. LARKIN, Scott D. LOVE, Scott MACADAM, Peter N. SLATER, Edward G. LATIMER, Richard B. MILLER

Patent number: 7128827Abstract: Integration of gas oil and light olefin catalytic cracking zones with a pyrolytic cracking zone to maximize efficient production of petrochemicals is disclosed. Integration of the units in parallel allows production of an overall product stream with maximum ethylene and/or propylene by routing various feedstreams and recycle streams to the appropriate cracking zone(s), e.g. ethane/propane to the steam pyrolysis zone and C4 C6 olefins to the light olefin cracking zone. This integration enhances the value of the material balances produced by the integrated units.Type: GrantFiled: January 14, 2004Date of Patent: October 31, 2006Assignee: Kellogg Brown & Root LLCInventors: Michael J. Tallman, Chris Santner, Richard B. Miller

Patent number: 6902593Abstract: A multi-cyclone gas/solids separator with reduced solids re-entrainment is disclosed. The separator uses a plurality of cyclones spaced horizontally apart from adjacent cyclones to process flue gas containing residual catalyst fines. Each cyclone has a body that has a feed inlet end for admitting gas and entrained solids into an annular space defined by a sidewall of the cyclone body and a cylindrical gas outlet tube axially aligned with the cyclone body. A solids outlet at an opposing end of the cyclone body has a tangential outlet for solids and a minor amount of gas through a sidewall of the cyclone body. A gas reflux opening is axially aligned with the outlet tube. The plurality of cyclones share both a common catch chamber for solids discharged from the solids outlet, and a common manifold for gas and entrained solids.Type: GrantFiled: February 26, 2003Date of Patent: June 7, 2005Assignee: Kellogg Brown and Root, Inc.Inventors: Richard B. Miller, Eusebius Gbordzoe, Yong-Lin Yang, Suisheng M. Dou, David Lee Johnson

Patent number: 6503460Abstract: Staged combustion in a single regenerator of a FCC unit is disclosed. The regenerator has a spent catalyst distributor at the top of the catalyst bed, and an air grid at the lower end of the bed. A baffle separates the catalyst bed into upper and lower stages. Excess oxygen is present in the lower bed; partial CO combustion mode is maintained in the upper bed. The baffle inhibits backmixing flux to achieve sufficient staging to burn the catalyst clean under partial CO combustion. This achieves a clean burn of the catalyst in a single regenerator vessel in the partial CO combustion operating mode. Surprisingly, the baffle also reduces catalyst entrainment in the dilute phase, thereby cutting particulate emissions from the regenerator and reducing cyclone wear.Type: GrantFiled: March 17, 1999Date of Patent: January 7, 2003Assignee: Kellogg Brown & Root, Inc.Inventors: Richard B. Miller, Yong-Lin Yang

Patent number: 5859884Abstract: An electrical circuit backfits into different instrumentation and control (I&C) system hardware configurations as a replacement or upgrade. The circuit has a multiple signal path processing circuit including a multi-functional ASIC. A fixedly configured, multiple signal path connector such as a hardwired multi-pin package removably connected with a pin socket in the processing circuit connects the ASIC with the I&C system for coupling inputs to and outputs from the ASIC and for selecting operative signal paths of the ASIC.Type: GrantFiled: November 11, 1997Date of Patent: January 12, 1999Assignee: Westinghouse Electric CorporationInventors: Bernard J. Metro, Carl A. Vitalbo, Richard B. Miller

Patent number: 5635140Abstract: A spent catalyst distributor in a fluid catalytic cracking unit regenerator is self aerated by attaching to the underside of each trough arm a contiguous lip which captures rising aeration fluid and uses the aeration fluid to aerate spent catalyst flowing through the trough arms of the spent catalyst distributor. Orifices in the bottom plate of each trough arm pass the captured aeration fluid up into the spent catalyst flowing within the trough arm. The aeration fluid provides aeration and fluidization of the spent catalyst to facilitate the flow of the spent catalyst through the trough arms of the spent catalyst distributor.Type: GrantFiled: November 13, 1995Date of Patent: June 3, 1997Assignee: The M. W. Kellogg CompanyInventors: Richard B. Miller, Paul L. Sestili

Patent number: 4581129Abstract: Deactivated hydrorefining catalysts are regenerated by incorporation of a phosphorus component followed by combustive coke-removal from the catalyst. The regenerated catalyst is useful for promoting hydrodesulfurization reactions, particularly those involving demetallation of hydrocarbons.Type: GrantFiled: September 17, 1984Date of Patent: April 8, 1986Assignee: Union Oil Company of CaliforniaInventors: Richard B. Miller, Ryden L. Richardson

Patent number: 4488854Abstract: A constrained wave pump for pumping fluids by oscillation of an elastic medium. Coaxially arranged cylindrical constraining surface and elastic member define a channel having an entrance and an exit port. A shaft creates variable frequency longitudinal oscillations in the elastic member which generate wave propagation therein. The peaks of the generated waves form a fluid seal with the constraining surface to produce a fluid pumping action from the entrance to the exit port.Type: GrantFiled: April 12, 1982Date of Patent: December 18, 1984Inventor: Richard B.
