A Rational Methodology for Determination of Service Life for a Delayed Coker Drum
Volume 3: Design and Analysis, 2015Delayed unit coker drums operate in a severe service environment that precludes long term reliability due to excessive shell bulging and cracking of shell joint and shell to skirt welds. Thermal fatigue is recognized as the leading damage mechanism and past work has provided an idealized description of the thermo-mechanical mechanism via local hot and ...

Application of Elastic-Plastic Methods to Delayed Coker Drum Design
Volume 3: Design and Analysis, 2011Coke drums are pressure vessels that are used in oil sands and conventional refinery processing industries for the thermal cracking of reduced bitumen to recover additional, saleable gas and liquid product streams. The drums are constructed to the requirements of ASME VIII Division 1 although they are in a low cycle thermal-mechanical service ...

The Making of Coke in the Delayed Coker and in the Slot Coking Oven [PDF]
, 1986 Coke is the highly carbonaceous product of pyrolysis of organic matter at least parts of which have passed through a liquid or liquid-crystalline state during the carbonization process and which consists of non-graphitic carbon.

Disturbance Modelling based Benefit estimation from Advanced Process Control: Case study on Delayed Coker Unit [PDF]
2019 Fifth Indian Control Conference (ICC), 2019 Benefit estimation is one of the key components for introducing Advanced Process Control (APC) / Multi-variable Predictive Control (MVPC) / Model Predictive Control (MPC) to a process, as the cost associated with it have to be justified in economic terms.

Abstract Delayed coking is an important process in refinery to convert heavy residue oils from crude distillation units (CDUs) and fluid catalytic cracking units (FCCUs) into dry gas, liquefied petroleum gas (LPG), gasoline, diesel, gas oils and cokes. The main fractionator, separating superheating reaction vapors from the coke drums into lighter oil

Data-Driven Soft Sensors for Process Industries: Case Study on a Delayed Coker Unit
Systems and Control TransactionsThis research addresses the challenges associated with data-driven soft sensors in industrial applications, where successful implementations remain limited. The scarcity of practical applications can be attributed to variable operating conditions and frequent disturbances in real-time processes.
