Valero Port Arthur refinery partially restarts after blast, according to sources

Two people familiar with the plant's operations said that Valero Energy Corp. has partially restarted their 380,000 barrels per day Port Arthur, Texas refinery after an explosion and fire on March 23.

Valero repairs the heater on the 210,000 bpd crude distillation unit (CDU) while the production line of the 115,000 bpd CDU is running. This production line is closed.

A Valero spokesperson failed to respond to a question for comment.

During an inspection of the units of the refinery following the 23 March shutdown of the unit due to the fire, Valero found a damaged tube within the AVU-146?heater. Valero intends to restart the CDU once the heater tube is repaired.

AVU 146 is a crude distillation unit that accounts for 2% or 9.62 million bpd of the crude oil refinery capacity of the U.S. Gulf Coast States of Texas, Mississippi, and Louisiana. This represents over half of 'the U.S. overall. AVU 146 is capable of 3.4% of Texas' total atmospheric crude distillation capability of 6.13 millions bpd.

CDUs work at atmospheric pressure, converting crude oil to?feedstocks? for other refinery units.

The March '23 explosion and fire at the diesel hydrotreater did not result in any injuries, but a?person filed a suit, claiming he was injured after being knocked down. Valero had previously refused to comment on the lawsuit.

Due to the shutdown of the refinery, the price of diesel rose by 16 cents per barrel the day after the explosion. (Reporting and editing by Nathan Crooks, Nick Zieminski, and Erwin Seba)
