(Updates with comment from Jackson County)
Nov 15 (Reuters) - One person was killed in an overnight fire at a processing unit of Chevron Corp's 330,000-barrel-per-day refinery in Pascagoula, Mississippi, a Jackson County emergency official said.
The fire was contained and extinguished by plant personnel, said Earl Etheridge, director of Jackson County Emergency Services. The refinery is Chevron's largest and most complex.
"There were unconfirmed reports of an explosion," Etheridge said. "There has been one confirmed death."
The fire came after a Chevron pipeline exploded on Thursday near a tiny Texas town south of Dallas, prompting evacuations from nearby homes and a school district.
A report with the WLOX News website quoted a Chevron statement saying the Pascagoula refinery experienced the fire at one of its processing units at around 2 a.m. Friday morning. (Report: http://link.reuters.com/pud74v)
Fire units from Pascagoula and Jackson County stood by outside of the plant and were released around 4 a.m., Etheridge said, adding that there was no threat to the environment or the public.
Chevron officials were not immediately available for comment.
The Pascagoula refinery can process and treat low-grade heavier, sour, foreign crude oil. It produces about 130,000 bpd of motor gasoline, 50,000 bpd of jet fuel and 68,000 bpd of diesel fuel, according to Chevron's website.
