Proceedings Papers

Proc. ASME. PVP2021, Volume 5: Operations, Applications, and Components; Seismic Engineering; Non-Destructive Examination, V005T07A006, July 13–15, 2021
Paper No: PVP2021-62435
.... Engineering analyses included stability analysis of the coke drum, development of a robust and technical viable repair plan, design of a lifting & rigging system to enable repair in the field, controlled deposition welding (CDW) approach, and detailed description of non-destructive examination (NDE...

Proc. ASME. PVP2021, Volume 2: Computer Technology and Bolted Joints; Design and Analysis, V002T03A001, July 13–15, 2021
Paper No: PVP2021-62939
...Abstract Abstract Low-cycle fatigue failure has been widely accepted as the key mechanism causing damages of coke drums during cyclic thermal-mechanical loadings. Common damages of coke drums known as bulging and cracking are associated with accumulative plasticity caused by thermal...

Proc. ASME. PVP2020, Volume 3: Design and Analysis, V003T03A003, August 3, 2020
Paper No: PVP2020-21574
...Abstract Abstract Coke drums are pressure vessels used in the delayed coking process at oil refineries, which transform heavy residual oil into light-weight hydrocarbon molecules and solid coke through thermal cracking. Due to the severe thermal and mechanical loadings during operation...

Proc. ASME. PVP2020, Volume 3: Design and Analysis, V003T03A002, August 3, 2020
Paper No: PVP2020-21485
...Abstract Abstract The coke drum is subjected to a combination of thermal-mechanical loads during operation, so its safety and reliability must be considered in actual production. In each production cycle, the thermal stress generated by temperature fluctuations in the coke drum is the main...

Proc. ASME. PVP2019, Volume 3: Design and Analysis, V003T03A004, July 14–19, 2019
Paper No: PVP2019-93661
... to limit the growth of bulges and to extend the remaining life of delayed coking drums. Different refinery operators have used varied approaches, ranging from localized patches on specific regions of concern, to bands along circumferential welds, to large sections of structural repair that completely cover...

Proc. ASME. PVP2013, Volume 3: Design and Analysis, V003T03A070, July 14–18, 2013
Paper No: PVP2013-97296
... Coke drums are major pressure vessels used in petroleum refineries. In this paper, two simplified analytical models based on thermo-elasto-plastic constitutive theory have been developed to evaluate global and local stresses in coke drums during their operation cycles. The first model considers...
