HOUSTON, Aug 15 (Reuters) - Pemex, Mexico’s national oil company, is preparing for the “Big Block” overhaul at its 312,500 barrel-per-day (bpd) Deer Park, Texas refinery to begin in early October, said people familiar with plant operations on Friday.
The refinery’s 270,000 DU-2 crude distillation unit (CDU), the larger of two at the refinery, will be shut for the planned overhaul that will continue for about 60 days, the sources said.
