Valero Energy Corp VLO.N plans to overhaul the large crude distillation unit (CDU) in January at it 235,000 barrel-per-day (bpd) Port Arthur, Texas, refinery, people familiar with plant operations said on Wednesday.

Valero plans to shut the 210,000-bpd AVU-146 CDU by Jan. 15 for the overhaul, which is expected to take 45 days, the sources said.

A Valero spokesperson did not reply to a request for comment on Wednesday.

Valero also plans to shut the coker associated with AVU-146 along with other units supplied with feedstocks from the crude unit.

CDUs begin the refining process by breaking down crude oil into feedstocks for all other units at the refinery. AVU-146 is the larger of two CDUs at the Port Arthur refinery.
