S.Korea SK Energy to shut No.4 refinery in Sept

SEOUL, July 13 (Reuters) - South Korea's SK Energy (096770.KS) will shut down its No.4 crude unit with a refining capacity of 240,000 barrels per day (bpd) in September for maintenance, traders said on Monday.

The country's top refinery, which has South Korea's largest crude refining capacity of 1.115 million bpd, will close the No.4 unit for a month due to poor margins after it skipped planned maintenance in April, they said.
