Petroleum Coke. Petroleum coke is a carbonaceous product obtained in the oil refining process. It is abbreviated as Coke or Petcoke, and is a carbon-rich solid material derived from final cracking process — a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units.
The most common materials for the shell and cone of coke drums are 1 Cr — ½ Mo and 1-1/4 Cr — ½ Mo, with almost all drums being constructed in low chrome alloys. The vast majority of drums in industry have a 410 SS lining.

It is used to produce coke from coal in steel making. Coking is as old as the hills. The town of Redstone in Colorado is now a well-known tourist attraction. In 1900 about 250 ovens were converting 6 million tpy of locally mined coal to coke for use in nearby metallurgical industries. Coke ovens in Redstone, Colorado.
The Martinez Refining Company reported at 10:20 a.m. through a community warning system that the released material was coke dust, a byproduct of the refining process, county health officials said.
The power failure and tarry drum accident that occurred at the Equilon, now Shell, Puget Sound Refinery, was an awakening for the delayed coking industry. Since then, the industry and the site have made significant improvements in safety and awareness of abnormal drum situations. The presentation will revisit the events of 1998 that cost 6 …

2 Coke Drums Self Destruct • Coke Drums are pressure vessels in batched, thermal cyclic service. • Operated for maximum production goals. • Cyclic wear and tear from thermal expansion self constraint is seen as metal fatigue and defect crack growths. • Eventually leaks happen. • And cracks are repaired. • And sometimes they are prevented.
