The Art of Delayed Coking

The one feature that differentiates a Delayed Coker from all (or at least most) other refinery operations is the handling of a solid product: petroleum coke. Although solids handling often causes problems in equipment reliability and environmental aspects, there are measures that can be taken to optimize these systems and achieve safe and reliable operation.

As coke buiilds up in the drum, the lighter products of cracking are recovered as overhead vapours and are taken to a fractionator for separation into various products. Petcoke yield is mainly dependent on the carbon content of the feedstock, while the structural quality of the Petcoke is influenced chiefly by the type of feed, i.e., crude or cracked products.

Delayed coking is a refining process that consists of the upgrading of petroleum residues into lighter and more valuable hydrocarbon fractions by promoting thermal cracking on the residue stream. Petroleum coke is a by-product of this process and depending on its morphology it can be used as fuel for steam generation, cement calcination or as feed stock for the manufacturing of aluminum and steel.
