HOUSTON (Reuters) - BP Plc began a planned overhaul on Wednesday of the small gasoline-producing fluidic catalytic cracking unit (FCCU) at its 430,000 barrel-per-day (bpd) Whiting, Indiana, refinery, said sources familiar with plant operations.
BP is continuing to increase production levels on the large crude distillation unit (CDU) at the refinery on Wednesday, but will not run the 240,000 Pipestill 12 CDU at full capacity, while the 65,000 bpd FCCU 600 is shut for the overhaul, the sources said.
FCCU 600 is expected to be shut for about a month to complete the overhaul, according to the sources.
Production was cut on Pipestill 12 on Tuesday because of a malfunction.
Pipestill 12 is the largest of three CDUs doing the primary breakdown of crude oil into hydrocarbon feedstocks for all other production units at the refinery.
