Delayed Cokers

The key areas of Delayed Coking Units that usually require decontamination at Turnarounds are the Main (or Coker) Fractionator. Alternatively, it can be the immediate downstream equipment, such as the Side-Cut Stripper, the Quench Tower and Separator.

As the Coker feed is typically Vacuum Residue, Sulphur compounds such as Hydrogen Sulphide, and pyrophoric Iron Sulphide, are likely to be an issue. CORE recommends a cascade washing technique for these vessels. These use formulations that can remove all hydrocarbon contamination safely and quickly. Separators may incorporate a Demister at the head of the vessel. Where prior history or our experience dictates, we add a final Oxidation wash to remove any residual pyrophoric compounds. This allows safe, rapid entry for maintenance crews following our procedure.
