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 WebThe growth of delayed cokers was in step with the growth of fluid catalytic cracking and rapid decline in thermal cracking. A fluid coker, similar to a fluid catalytic cracker except …
WebThe delayed coker model provides a fundamental kinetic representation of the delayed coker operation, and the input page is shown in Figure 2.

WebAug 5, 2024 · Coking (delayed, fluid and flexi) is one of the types of carbon rejection processes. Delayed coking has been chosen by many refineries as an upgrading process due to its low investment cost and the inherent flexibility of the process to process any residuals. In this process, 20–30 wt.% coke is produced as a by-product. shuttleworth llcWebCoking 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.
