Radiometric levels on delayed cokers – lessons learned from a recent startup

Presented By

David Williams - Berthold Technologies

Conference: Rotterdam 2019

This presentation focuses on lessons learned from a recent startup of a delayed coker unit, including the proper installation, mounting and design of radiometric level solutions.  At a recent startup, a lot of time and money was spent to correct issues that could have been prevented with proper design. Some issues were as follows:

  • Where to mount the radioactive sources on the drum?  
  • Prevention of radiological safety issues.
  • How to prevent alignment issue and prevent erroneous readings? 
  • How to ensure proper operation of the level system?
