HOUSTON, Aug. 20 (Reuters) – Diesel and gasoline production fell about a third at Galveston Bay’s 593,000-barrel-per-day (MPP) refinery at Marathon Petroleum Corp (MPC.N) in Texas City, Texas. after a key compressor outage on Thursday, sources familiar with plant operations said Friday.
Marathon spokesman Jamal Kheiry declined to comment.
The key hydroprocessor compressor, which uses the refinery’s diesel hydrocracker and two reformers, is being repaired after shutting down Thursday, sources said.
Marathon expects to complete compressor repairs over the weekend, according to sources.
The 60,000 bpd diesel hydrocracker, called the Ultracracker, shut down and restarted Thursday, but with reduced production due to the compressor cut, sources said.
The 75,000 bpd Ultraformer 3 reformer and the 65,000 bpd Ultraformer 4 reformer were reduced, as was the 140,000 bpd gasoline-producing catalytic cracker (FCC 3), according to sources.
Reformers convert refined by-products into octane-increasing components added to obtain gasoline finishes.
Marathon is the largest refiner in the United States by capacity. The Galveston Bay refinery is the second largest in the United States.
