WebTraditionally, to minimize the quantity of coke formed, the pressure in the coke drum is set at minimum levels. In today's delayed cokers, the minimum practical pressure level is 6.89 x 10⁴ to 1.03 x 10⁵ Nm⁻² (10 to 15 psig). To achieve lower pressures requires large and expensive equipment with high compression requirements. WebJul 3, 2024 · Three types of coking process are delay coking, fluid coking and Flexicoking.

WebJan 28, 2013 · With delayed coking, two or more large reactors, called coke drums, are used to hold, or delay, the heated feedstock while the cracking takes place. Coke is deposited in the coke drum as a solid. This solid … WebThe delayed coking process involves heating hydrocarbon liquids in a coking furnace and transferring the heated liquids to a coking drum where the liquids decompose into coke and volatile components. In order to practically use the delayed coking process, a coker fractionation system is needed along with the coking furnace and coking drums.
WebJul 2, 2016 · Cokers used in the oil sands are either Delayed Cokers, a batch process taking about 10 to 16 hours per cycle, or Fluid Cokers, which are more complex, continuous coking units.

WebCoking is the primary process used to upgrade petroleum residues. This process produces a solid coke which has a high carbon content. There are two types of coking processes, fluid cokers and delayed cokers. The delayed coking process is much more prevalent. In delayed coking, the process is designed so that the coke forms in a drum.
Webproperties [12]. Flexi coking differs from fluid coking only because of the presence of gasification unit in flexi-coking. In flexi coking there is complete or partial gasification of the petroleum coke to yield a fuel gas. It is different from the bulk liquid-phase coking in delayed coking. In flexi coking technical programs in philadelphiaWebA fluid coker is a simplified version of a flexicoker in which coke is continuously drawn off, but only gasified to the extent necessary to fuel the coking process.
