- In an update on its refinery maintenance, HollyFrontier (HFC -1.2%) says that unplanned Q4 maintenance on its Navajo Catalytic Reforming Unit has wrapped up -- and that cold weather there resulted in boiler outages that affected run rates.
- Issues with the CRU at Tulsa also caused a rate reduction, it says. That refinery will use downtime to accerlate maintenance for units originally planned for later in 2017, including the East Crude Unit.
- Because of the maintenance, HollyFrontier now says it expects crude oil throughput for the quarter to average 425,000 to 435,000 barrels per day.
