HOUSTON, June 1 (Reuters) - Royal Dutch Shell Plc
restarted the crude distillation unit (CDU), coker and
gasoline-producing cat cracker by Monday at its 225,300
barrel-per-day (bpd) Norco, Louisiana, refinery, said sources
familiar with plant operations.
Shell is restarting the hydrocracker, while the reformer and
naphtha hydrotreater will remain shut for previously planned
work, the sources said. 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, according to the sources.
After correcting the CDU malfunction, Shell restarted the
crude unit, which began sending hydrocarbon feedstock to the
other units allowing them to restart, the sources said.
