(Adds company no reply)
HOUSTON, Oct 30 (Reuters) - Total SA cut production to minimum rates on Wednesday at its 225,500-barrel-per-day (bpd) Port Arthur, Texas, refinery after a sulfur recovery unit (SRU) shut down, said Gulf Coast market sources.
A company spokeswoman did not reply to an emailed request for comment.
Units at the refinery were operating at between 50% and 70% of their capacity after SRU 3 was shut due to a malfunction, the sources said.
SRU 3 is expected to restart within a few days, the sources said.
SRUs stand at the end of a chain of units removing sulfur from motor fuels in compliance with U.S. environmental rules. If the sulfur cannot be removed to comply with the regulations, refineries will reduce production. (Reporting by Erwin Seba; Editing by Sandra Maler and Muralikumar Anantharaman)
