Description:

In order to increase the value of heavy oils, many refiners use delayed coking. This heavy oil upgrading scheme is really the last-remaining batch process utilized in petroleum crude refineries. There are currently 63 DCU’s operating in the US, and more around the world. Becht is proud to provide an in-depth discussion of this unique process which involves high temperatures, complex chemistry, and very unique specialty equipment and systems. Safety, Reliability, Design & Troubleshooting considerations are woven into the presentation topics. Daily group problem solving sessions are included relative to real world problems and economic considerations. Just a few of the learning objectives are understanding…

  • How a coke bed forms
  • Trade-offs in coker feed rate and equipment reliability
  • The difference between coker natural recycle and distillate recycle
  • How to effectively on-line spall coke from furnace tubes
  • What a coker blowdown system does
  • How to safely & reliably get coke out of the drum, and much more….

Final Discussion / Q & A
Who Should Attend:

The presentation applies to those professionals who are interested in getting a thorough introduction to all aspects (process, mechanical & operational) of delayed coking as part of a full 3-day course. It is primarily oriented toward engineers, operations personnel and service providers grounded in refining fundamentals – tower fractionation & heat balances, pump operations, valve basics, and fluid flow.
