Sources say that TotalEnergies Texas refinery has begun a small unit overhaul.

TotalEnergies has begun a 60-day planned overhaul of the small crude distillation units (CDUs), as well as a reformer, and hydrotreaters, at its Port Arthur, Texas refinery that produces 238,000 barrels per day, according to people familiar with plant operation.

Sources said that the 35,000 bpd continuous catalyst reformer (CCR), along with three diesel hydrotreaters, with a combined output of 84,000 bpd and a naphtha hydrotreater with a throughput 42,000 bpd and a sulfur unit were closed along with the ACU-2 CDU with its 51,000 bpd vacuum distillation unit-1 (VDU-1), they added.

A TotalEnergies representative did not respond to a comment request on Tuesday evening.

ACU-2 will be shut down, but ACU-1 CDU (150 000 bpd) will continue to operate.

CDUs work at atmospheric pressure to break crude oil down into feedstock for other refinery units.

The VDUs are also capable of converting crude oil to feedstocks but they operate under vacuum pressure.

Reformers add octane boosting components to unfinished gas by converting refining waste.

Hydrotreaters are used to remove sulfur from motor oils and feedstocks in order to comply with U.S. Environmental rules.
