  • Patent number: 6332975
    Abstract: The invention is a process for making anode grade coke which comprises solvent deasphalting a residue feedstock to obtain an essentially asphaltene-free, resin-containing stream and coking the resin-containing stream in a delayed coker to make anode coke. The solvent deasphalting can make a deasphalted oil stream containing resin or separate deasphalted oil and resin streams. There can be hydrotreating of (1) a minor portion of the residue feedstock wherein the hydrotreated residue is fed to the delayed coker with the resin-containing stream, (2) the resin-containing stream wherein the hydrotreated resin stream is fed to the delayed coker, or (3) a major portion of the residue feedstock wherein the hydrotreated residue is fed to the solvent deasphalting unit.

  • Patent number: 5500094
    Abstract: A vessel unheading device and method especially suited to handle shot coke produced in a delayed coker unit of a petroleum refining process. The device includes a car having mounted thereon one or more bottom head retracting support members which can be laterally positioned below the head assembly. The support member includes a vertically retractable member suitable for elevating a bearing plate mounted at an upper end thereof into pivotable load bearing engagement with the head, and a horizontally retractable member having one end attached to the bearing plate and another end attached to the vertically retractable member for applying a pivot force. Shot coke or other debris is captured from the opened vessel by a mobile chute wheeled into position adjacent the unheading car. Following complete retraction, the head is transported to a remote location for maintenance.
