INTERNAL LINING FOR DELAYED COKER DRUM

摘要

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.

主权项

1. A delayed coking drum consisting of a top ellipsoidal or hemispherical head, a bottom conical head with an outlet for coke product, and a vertical cylindrical section, with a vapor outlet at the top and a feed inlet at/near the bottom, with a shock-resistant and erosion-resistant internal lining applied to the inner surface of the drum.
