How investors may read it

The Coker Hydrotreater treats streams from the coker unit as part of the refinery's processing chain. An isolated unit typically stays out of service until inspection and repair, so investors will watch for follow-up updates on the extent of damage, restart timelines and any effect on refinery throughput.
