Marathon Petroleum Corp. has delayed the start of maintenance on a fluid catalytic cracker at the Catlettsburg, Kentucky, refinery from this week to Sept. 15, according to a person familiar with the work.
Maintenance on the unit is scheduled to last about 40 days, said the person, who asked not to be identified because the information isn’t public.
Fluid catalytic crackers process vacuum gasoil into higher-value gasoline and other lighter products.
Jamal Kheiry, spokesman for Marathon in Findlay, Ohio, declined to comment on operations.
The Catlettsburg refinery, in northeastern Kentucky on the Big Sandy River, has a capacity of 240,000 barrels a day. The plant processes a wide range of both sweet and sour crude oils and distributes products by pipeline, barge, truck and rail, according to Marathon’s website.
