HOUSTON, Aug 21 (Reuters) - Motiva Enterprises LLC reported a pump fire in a process unit at its 235,000barrels-per-day (bpd) refinery in Convent, Louisiana, accordingto a regulatory filing.
The filing with the Louisiana Department of EnvironmentalQuality did not specify the unit where the pump fire occurred onMonday.
Royal Dutch Shell Plc, which operates the refineryit co-owns with Saudi Aramco, said on Wednesday thatthe Convent refinery shut the unit after an operational issuethat resulted in a fire. Onsite responders quickly extinguishedthe blaze and no one was hurt, a spokeswoman said.
The filing said the fire did not cause any offsite impact.
The Convent fire came two days after a fire broke out in ahydrocracker on Saturday at Motiva's 600,000 bpd refinery inPort Arthur, Texas, the largest in the United States.
The shutdown of the damaged hydrocracker and a sulfurrecovery unit forced the shutdown of the plant's new 325,000 bpdcrude distillation unit as well, the centerpiece of a $10billion expansion that has faced repeated problems. (Reporting By Kristen Hays; Editing by Kenneth Barry and AndreGrenon)
