Non-operator Tower of the Coker – Interlock and Automization

Presented By

Guenter Breuer - BP Gelsenkirchen

Dr. Asli Nau - BP Gelsenkirchen

Conference: Rotterdam 2019

Due to an accident in 2001, Gelsenkirchen refinery decided to automize the coker operation to minimize the residence time for the operator in the structure to a minimum. The BP coker in Gelsenkirchen (Germany) is an example of a retrofit that has taken time but the continued devotion to the process is an example to the industry that CAN and SHOULD be done. Operations and Technology would like to share their experiences in increasing safety in the semi-batch process of a coker. All process steps (drum switch / disconnecting and stripping / quenching and draining / cutting pressure test/warm-up) are completely automized.

  1. Non-Operator drum operation – maximum safety
  2. Operator convenience
  3. Transparency and monitoring
  4. Harmonize Coker operation over all shifts
  5. Exclusion of false operation (High Level Interlock)
  6. Provision of rapid fault diagnosis and debugging
  7. Visualization of all program steps in the DCS
  8. Flexible sequence parameters to optimize cycle time
  9. Reliable operation
