The refining complex in Jamnagar has two refineries. : India's private refiner Reliance Industry said on Wednesday a secondary unit at its export-focussed refinery in the western state of Gujarat has been shut since June 6, which may delay the shipment of some product cargoes. The refinery, which has the capacity to process 704,000 barrels of crude per day (bpd), is part of the world's biggest refining complex in the city of Jamnagar in Gujarat state. Reliance, which operates the refining complex, did not give a reason for the "emergency shutdown" of the refinery's fluidized catalytic cracking unit (FCCU).
