  • Patent number: 5286371
    Abstract: A process is provided for producing premium and super premium grade needle coke comprising the steps of passing a heavy resid feedstock to a resid hydrotreating reaction zone at resid hydrotreating conditions and producing light resid hydrotreated products and a heavy resid hydrotreated residual product, directing the heavy resid hydrotreated residual product and FCC decanted oil to a solvent extraction process reaction zone at solvent extraction process conditions and producing products comprising a solvent extracted oil and resin stream and a stream comprising asphaltenes, and conveying at least a portion of the solvent extracted oil and resin stream to a delayed coking process at delayed coking conditions and producing liquid products and premium grade coke.
    Type: Grant
    Filed: July 14, 1992
    Date of Patent: February 15, 1994
    Assignee: Amoco Corporation
    Inventors: Shri K. Goval, Jeffrey J. Kolstad, F. W. Hauschildt, Dean G. Venardos, Cheryl L. M. Joval
  • Patent number: 5110449
    Abstract: A process is disclosed for sludge addition to a coking zone in which the sludge is contacted with oxygen. The sludge is then contacted with feed, liquid derived from the feed, or vapor derived from the feed. Oxygen also contacts the feed, liquid derived from the feed, or vapor derived from the feed to help maintain reaction temperature in the coking zone.
    Type: Grant

    Date of Patent: May 5, 1992
    Assignee: Amoco Corporation
    Inventors: Dean G. Venardos, Shri K. Goyal
  • Patent number: 5041207
    Abstract: A process is disclosed wherein at least two separate gaseous oxygen streams are passed into a coker transfer line to effect oxidation of a portion of the feed passing through the transfer line. Another aspect of the process is disclosed wherein gaseous oxygen is passed into a coking process and sludge is also passed into the coking process.

  • Patent number: 4585063
    Abstract: An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water. The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil/water separator. After the retort water is separated from the shale oil, the retort water is steam stripped, carbon adsorbed and biologically treated, preferably by granular carbon adsorbers followed by activated sludge treatment or by activated sludge containing powdered activated carbon. The retort water can be granularly filtered before being steam stripped. The purified retort water can be used in various other oil shale processes, such as dedusting, scrubbing, spent shale moisturing, backfilling, in situ feed gas injection and pulsed combustion.
