The refinery, which was initially expected to do the work as part of maintenance this month, will halt to replace an exchanger on the sulfur unit, said the people, who asked not to be identified because the information isn’t public. Work on a fluid catalytic cracker is planned for the fall of 2014, one of the people said.
The plant’s current turnaround, which began early this month and is expected to last about 40 days, includes a coker, crude unit and hydrocracker, according to the people. Some maintenance is also being conducted on a hydrogen plant and desulfurizer, they said.
Cokers convert heavy refinery streams, such as vacuum bottoms, into light products such as naphtha and heating oil. Hydrocrackers refine heavy feedstocks into lighter fuels such as high-octane gasoline or fuel oil, while FCCs upgrade vacuum gasoil into lighter petroleum products including gasoline and jet fuel.
Michael Karlovich, a PBF spokesman based in Parsippany, New Jersey, declined to comment.
The Delaware City refinery can process 182,200 barrels a day, according to data compiled by Bloomberg. The site runs heavy high-sulfur crudes and recently completed a project that boosted its ability to receive Bakken crude by rail to about 160,000 barrels a day, according to the company. It receives an additional 30,000 barrels a day by barge.
