  • Patent number: 10352619
    Abstract: An anchor assembly for anchoring refractory materials within a vessel is disclosed that provides for a more reliable refractory anchor and resultant refractory lining system that is easier to install both in terms of the refractory lining and the anchor assembly itself when compared to prior art anchor assemblies. The anchor assembly includes a base pin assembly, and at least one anchor leg connected to and extending from the base pin assembly. The base pin assembly includes a mounting end formed on one end of the pin assembly adapted for securing the base pin assembly to the vessel. The mounting end has an electrical resistance contact point formed thereon. The electrical resistant contact point preferably has a flux material located thereon.

  • Patent number: 10047298
    Abstract: A delayed coking unit has a thermal shock-resistant, erosion-resistant internal lining to reduce thermally-induced mechanical stresses in the pressure boundary of the coke drum. The lining is effective to reduce or mitigate the transient thermal stress that occurs in the pressure boundary of the coke drum and to reduce or minimize the high thermal stress resulting from temperature differentials at the skirt-to-shell junction.
