Furnace Trip and Foamover Lesson Learned

Presented By

Gary Gianzon - Marathon Petroleum

Conference: Galveston 2018

The presentation will share two recent events at different facilities and how these abnormal events were managed. The first event is a furnace trip that led to a potential for a tarry drum. After steam and quenching, the residual water would not drain. A number of novel mitigations were put into place before opening the bottom slide valve. In the second event, cold weather caused condensate to be present in the drum inlet steam purges. The secondary impact was a lower than normal drum inlet and outlet condition that subsequently resulted in a foam over. Awareness of how these events occurred and subsequent recovery action plans should be considered by all coker sites.
