RE: New Chinese Cokers may not be useableas someone who was at horizon during the fire rebuild, I can tell you that is probably a BS rumor. CNRL doesnt need to replace any cokers and they have 2 extras sitting on site that have been there since 2007 .
most of the costs from the coker fire were a result of pipes and heat exchangers freezing and cracking because it was -20 when they were shut down. also the structure above the coker was replaced and the coker internals.
