Catalytic Co-Processing of delayed coker light naphtha with other refinery gasoline streams [PDF]
Periodica Polytechnica Chemical Engineering, 2009 Upgrading of delayed coker light naphtha is very difficult due to its high diolefin and silicon content. Mixtures of light straight run naphtha and delayed coker light naphtha fractions were hydrotreated in two stages over NiMo/Al 2 O and CoMo/Al 2 O catalysts (diolefin saturation followed by hydrodesulphurization ).

Exergy Study of Sour Water Stripper Unit of Delayed Coker Unit in a Refinery plant: A Real Start-Up Plant [PDF]
Egyptian Journal of Chemistry, 2021 Process sour water produced from refinery contains some hazardous pollutants as (H2S and NH3). Sour water stripper units remove both compounds from water. The two stripped pollutants are sent to Sulphur recovery unit to produce Sulphur and prevent any acidic emissions against environmental regulations.

Analysis of the mechanical behavior of a delayed coker drum with a circumferentially cracked skirt
Procedia Structural Integrity, 2017 Abstract: The skirts of four coke drums of a delayed coker plant in an oil refinery became severely cracked as result of the service and a poor design. The cracks were located in the circumference just below the welded joint of the skirt with the pressure vessel of the coke drums.

Effect of composition of coke deposited in delayed coker furnace tubes on on-line spalling
Fuel Processing Technology, 2018 Abstract Delayed coking is one of the most widely used residue upgradation process in crude oil refining where vacuum residue is thermally cracked and converted into distillates and petroleum coke. During heating of vacuum residue in coker furnace, coke is continuously deposited in furnace tubes which is removed at regular intervals by one of the ...
