  • Scrubber for fluid coker unit
    Patent number: 8066949
    Abstract: Fouling in the scrubber section of a fluid coker unit is reduced by providing perforated baffles to improve the uniformity of the gas flow profile in the scrubber by reducing the gas velocity of the cyclone outlet gases in the scrubber section of the unit. These baffles are located with the objective of reducing the rotational component of the gas flow in the scrubber created by the alignment of the gas outlets of the cyclones. The baffles are preferably located in the shed section of the scrubber and comprise upstanding perforated plates located at the periphery of the scrubber section to disrupt high velocity gas jets in the region of the interior wall of the scrubber.
    Type: Grant
    Filed: September 26, 2008
    Date of Patent: November 29, 2011
    Assignee: ExxonMobil Research & Engineering Company
    Inventors: Craig A. McKnight, Larry P. Hackman, Brian A. Knapper, Daniel Bulbuc, George B. Jones, Jonathan Tyler, Darwin E. Kiel

  • Hydrocarbon processing apparatus
    Patent number: 5624642
    Abstract: Apparatus and methods useful for degassing a reaction mixture in a petrochemical processing reactor are disclosed. The methods and apparatus employ a novel liquid-gas separator that includes non-linear risers and that discharges the mixture into a vapor space in a manner intended to maximize degassing of the mixture. Resid hydrotreating processes employing these methods also are disclosed.

  • Purification process for bitumen froth
    Patent number: 4859317
    Abstract: Bitumen froth is treated in a circuit comprising a plurality of serially connected mixer and inclined plate settler units. A light hydrocarbon diluent moves countercurrently through the circuit. Thus, as the bitumen content of the stream being settled diminishes, the concentration of diluent in that stream increases.
