Structural design guidelines for Delayed Coker Unit (DCU) used in hydrocarbon industry
Multidiscipline Modeling in Materials and Structures, 2021PurposeDelays in projects execution due to improper structural design lead to substantial losses to the owners. Little guidelines are available in practice that deals with structural design of Delayed Coker Units (DCUs). This work describes effective structural criteria for design of DCU used in hydrocarbon industry. Economical procedures are described

Coke bed structure in a delayed coker
Carbon, 2000The porous structure of the coke bed in a delayed coking reactor is investigated in order to understand how flow channels are formed and how the cooling water distributes during the quench stage of the reactor cycle. Tomography, gas expansion, pycnometry and mercury injection are performed in an attempt to associate the bed characteristics with the ...

DEPOSIT FORMATION IN INDUSTRIAL DELAYED COKER/ VISBREAKER HEATERS
Petroleum Science and Technology, 1998ABSTRACT In order to investigate fouling parameters indicative of the propensity of a furnace charge to form deposits in commercial coker/ visbreaker heater, 30+ processed furnace charge streams from more than 20 plant deposits were studied In general, about 90% of the deposits formed appear to be due to coke formation, and approximately 5% is due to ...

Determination of Service Life for Undamaged and Damaged Delayed Coker Drums
Volume 3: Design and Analysis, 2016A stated goal of governments in addressing climate warming and to transition to a low carbon future by the end of this century is to increase the proportion of energy supplied by alternative sources. For the hydrocarbon processing industry, the question of stranded assets will become significant as these alternative energy sources become more prevalent.

Corrosion Fatigue Performance of Materials in Delayed Cokers and Coker Blowdown Piping System
CONFERENCE 2024Abstract Very often the current body of knowledge and literature of fatigue performance in coke drums and blowdown piping system are linked to fatigue testing performed in air or in water. This paper summarizes the test results that were conducted using process fluids collected from a delayed coker.

Delayed coking is the technology most used to upgrade vacuum residue into high-value products, but in this process, secondary reactions produce coke. It is already known that the chemical and physical properties and composition of the feedstock and processing conditions affect coke morphology. Recently, a new type of morphology, called transition coke,

Delayed Coker Furnace Fouling Control – Laboratory Correlation to Field Experience
CORROSION 2008, 2008Abstract The problem of fouling is treated from three points of view; laboratory, plant, and economic. A laboratory apparatus, which simulates a furnace operating in a fouling mode, is discussed and test results are given for real situations. Two fouling problems, which occur in operating refinery furnaces, are evaluated with and without

Further Considerations for the Determination of Service Life for Delayed Coker Drums
Volume 3B: Design and Analysis, 2018Delayed coker drums are unique in hydrocarbon processing facilities in that estimating their true design and service life has been problematic. Generally, pressure containing equipment in these facilities is designed using the notion of design life based on required pressure thickness and corrosion allowance considerations.

Catalytic Coprocessing of Delayed Coker Light Naphtha with Light Straight-run Naphtha/FCC Gasoline
Petroleum Science and Technology, 2010Abstract Upgrading of delayed coker light naphtha (DCLN) is difficult due to its high diolefin and silicon content. Mixtures of light straight-run naphtha (LSRN) and DCLN fractions were hydrotreated in two stages over NiMo/Al2O3 and CoMo/Al2O3 catalysts (diolefin saturation followed by hydrodesulphurization (HDS).
