HOUSTON: Royal Dutch Shell Plc restarted on Saturday the gasoline-producing unit at its 218,200 barrel per day (bpd) Norco, Louisiana, refinery, sources familiar with plant operations said on Monday.
The 112,000-bpd gasoline-producing Residual Catalytic Cracking Unit (RCCU) was shut on March 7 for a planned overhaul, the sources said. Shell began preparing the unit for restart on May 12.
The company began restarting production on Thursday.
The 50,000-bpd gasoline hydrotreater malfunctioned on Sunday and is expected to return to normal operation between Monday and Wednesday, the sources said.
The RCCU is unlike most gasoline-producing catalytic cracking units in that it uses residual crude oil as its feedstock for making unfinished gasoline.
The more common fluidic catalytic cracking unit uses gas oil.
