World’s Best Delayed Cokers

Delayed cokers analysis identifies areas for improvement

In preparing its World’s Best 2–3 Drum Delayed Cokers (WB2D) and World’s Best 4+ Drum Delayed Cokers (WB4+D) analyses, Solomon relied heavily on its extensive and proprietary database to identify characteristics of the best 2–3 drum and 4+ drum delayed coking units in the Worldwide Fuels Refinery Performance Analysis (Fuels Study).

The database included 76 cokers with a 2- or 3-drum configuration and 73 cokers with a 4-drum or larger configuration. The analysis itself focused on identifying units that demonstrated sustainable, cost-effective, and high operational availability while yielding the largest percentage of non-coke products. Results of this analysis offer valuable insight toward helping operators evaluate their own delayed coking units and identifying possible focus areas for improvement.

Solomon metrics used to identify the World’s Best include the following:

  • Unit Operational Availability (OA)
  • Relative Unit Maintenance Cost Efficiency Index (MEI™)
  • Yield Gap versus the Top 25% of Units

These metrics mirror what most clients demand from their delayed coking units: reliable operations at a reasonable maintenance cost.
