Valero Energy Corp shut production on the small crude distillation unit (CDU) at its 180,000 barrel-per-day (bpd) Memphis, Tennessee, refinery on Monday for repairs, sources familiar with plant operations said.
A Valero spokeswoman did not reply to a request for comment.
Valero plans to keep the 80,000 bpd CDU shut until July 25 for unplanned repairs to clean out fouling from crude oil, the sources said.
