HOUSTON (Reuters) - The heavy oil hydrocracking unit (HCU) at Royal Dutch Shell Plc's (RDSa.AS) 209,787 barrel per day (bpd) Convent, Louisiana, refinery was shut after a fire early on Sunday, sources familiar with plant operations said.
The fire broke out on the 45,000 bpd HCU, call the H-Oil Unit, at about 1:30 a.m. (0630 GMT) on Sunday, the sources said.
A Shell spokesman was not immediately available to comment.
No injuries were reported due to the blaze, the sources said.
The H-Oil Unit is a unique hydrocracker because it converts residual crude oil into motor fuels, especially diesel. Residual crude is normally processed by coking units. Hydrocrackers use hydrogen and a catalyst under high heat and pressure to produce motor fuels.
