how petroleum delayed coke forms in a drum strength
Cokes | Article about cokes by The Free Dictionary
Petroleum coke is the solid residue left by the cracking process of oil refining. Natural coke, or carbonite, is formed by metamorphism metamorphism, in geology, process of change in the structure, texture, or composition of rocks caused by agents of heat, deforming pressure, shearing stress, hot, chemically active fluids, or a coination of these, acting while the rock being changed remains

Delayed Coking • The reactor system consists of a short contact-time heater coupled to a large drum in which the preheated feed “soaks” on a batch basis. Coke gradually forms in the drum. A delayed coking unit has at least a pair of drums.
Assessment of the Influence of Central and Lateral Feed …
A statistical analysis was performed using 40 thermal cycles of the two coke drums with central feeding system and 120 thermal cycles of the same coke drums after changing to lateral feeding system. The usage factor was estimated for each cycle considering the axial stress amplitude and a fatigue strength reduction factor of 2 for the ASME S-N design curve Fig. KD-320.2.

Flash Drum Operating Conditions
16 · The size a vapor-liquid separator drum (or knock-out pot, or flash drum, or compressor suction drum) should be dictated by the anticipated flow rate of vapor and liquid from the drum. With an operating temperature of 240°C and 52 bar(g) operating pressure, the autoclave vessel is the heart of a new POX facility for treatment of double-refractory (high carbon) sulphide concentrates.
