Royal Dutch Shell Plc shut on Saturday the gasoline-producing fluidic catalytic cracker at its 318,000 barrel-per-day joint-venture Deer Park, Texas, refinery after a fire, sources familiar with plant operations said on Sunday. All individuals were safe and accounted for at the Shell Deer Park Complex, which includes the refinery and adjoining chemical plant. The Deer Park refinery is a 50-50 joint venture between Shell and Pemex, Mexico’s national oil company.
