Deep-freeze issues still lingering FacebookTwitterEmail FILE -- Steam and fog rise from the Total refinery in Port Arthur, Texas on Dec. 21, 2020.Brandon Thibodeaux/NYT (Bloomberg) -- Texas’s refining complex is mostly back from last month’s crippling cold blast, but lingering freeze-related issues continue to plague a number of production units. More than six weeks after the Arctic storm took down at least 18 of the state’s 30 refineries, and almost 5 million barrels a day of crude-processing capacity, two of the plants still haven’t restored operations. But at a number of sites, equipment ranging from fluid catalytic crackers to crude units are still struggling. It’s an old story: Refineries don’t respond well to being restarted after unplanned total shutdowns, be it from winter storms, hurricanes or flooding.
