CNRL restarting Horizon bitumen upgrader

Canadian Natural Resources Ltd. has begun to restart the Horizon bitumen upgrader, which it shut down Feb. 5 for unplanned maintenance on the fractionating unit (OGJ Online, Feb. 15, 2012).

The upgrader, at CNRL’s oil sands mining operation north of Fort McMurray, Alta., can produce 110,000 b/d of synthetic crude oil and is scheduled for expansion in phases to 232,000-250,000 b/d.
