Delayed coking in the oil & gas industry
High temperature toleration
The Delayed Coking process is applied to the residual heavy oil, also called residuum feed, which emerges from the bottom of the vacuum distillation column. Via the bottom feed from a further fractionator column, this is fed, with steam, to another furnace and into coke drums. This cracks the heavy, long chain hydrocarbon molecules into coker gas oil and solid petroleum coke. The solid coke deposit remains in the coke drum, and the gas oil and lighter components in the vapour phase are fed back to the fractionator, to separate out the light gas oil, heavy gas oil and naphtha.
