Shell's Convent, Louisiana refinery contractors released from hospital: sources

HOUSTON (Reuters) - Two contractors who were burned last week in a fire at Royal Dutch Shell Plc's Convent, Louisiana, refinery have been released from the hospital, sources familiar with plant operations said on Monday.

The two contractors, who the sources said were released from the hospital on Friday, were among four workers injured in a flash fire on a hydrogen like while working on a tail gas treatment unit last Wednesday.

Tail gas treatment units use hydrogen to remove sulfur from motor fuels and their feedstocks.

The other two workers injured in the fire were able to return to work the same day.

The 209,787 barrel-per-day Convent refinery is performing a two-month overhaul of the gasoline-producing fluidic catalytic cracking unit and other units, the sources said.
