Coker people watch your blowdown finfans!!!
PSA on a cold night here in the Gulf. The coker blowdown has many hours of in-operation and can get cold. Having worked in Fort McMurray in the winter, I’m all too familiar with the procedures to keep these cooler warm and flowing.
Here are some ideas for my friend in Houston regarding freeze protection:
• Close the louvers when not in use
• Add roughneck heater to the deck below the cooler
• Use temporary tarps or some type of sheeting to restrict air flow from below
• Monitor the air coolers with IR cameras to look for cold spots
• Add steam to the bundles if available.
Remember, the banks can he plugged by frozen water but also condensed waxes. So aim to keep them above 65F at a minimum, >100F is even better.
