ABSTRACT:
A coke drum skirt to minimize the stresses experienced by the coke drum and the supporting structure of the coke drum is described. The skirt includes one circumferential horizontal plate attached to the coke drum, and the circumferential horizontal plate is slidingly sandwiched between a lower supporting plate that supports the weight of the drum through the circumferential horizontal plate and an upper retaining plate that prevents the coke drum from tipping or falling over. The upper retaining plate may be embodied as a series of retaining clips that also keep the coke drum centered and prevent rotation of the coke drum. The upper and lower plates are anchored to a concrete support base. The sliding connection of the plates allows the coke drum to thermally expand and contract while reducing stresses and metal fatigue from the typical fixed securing of the coke drum to the support base.
