Shell halted loadings of oil products from the refinery after a fire and reported a hydrogen fluoride leak Monday evening.

British-Dutch oil and gas company Royal Dutch Shell (RDS.A - Get Report) said Tuesday that the earliest restart of Europe's largest oil refinery is in the second half of August, Reuters reports.

The multinational oil conglomerate shut down most of its operations at the 404,000 barrel per day Pernis oil refinery in the Netherlands after a fire last week caused a power outage.

"We expect to restart our operations at the earliest in the second half of August," a Shell spokesman said. "We regret the impact this may cause for our customers, and we are doing everything we can to minimize impact."

Shell halted the loading of oil products from the refinery after the fire and reported a hydrogen fluoride leak on Monday evening.

Shares of Shell were climbing higher during Tuesday morning trading.
