Shell Plc restarted the crude distillation unit (CDU), coker and gasoline-producing cat cracker at its 225,300 barrel-per-day (bpd) Norco, Louisiana, refinery. Shell is restarting the hydrocracker, while the reformer and naphtha hydrotreater will remain shut for previously planned work. The coker is scheduled to undergo planned work beginning next week but is expected to remain in operation.
The 240,000-bpd CDU malfunctioned on Thursday night and shut down early on Friday, forcing the shutdown of the 112,000-bpd residual catalytic cracker, 25,000-bpd coker, 40,000-bpd hydrocracker, 40,000-bpd reformer and 40,000-bpd naphtha hydrotreater. After correcting the CDU malfunction, Shell restarted the crude unit, which began sending hydrocarbon feedstock to the other units allowing them to restart.
