Mangalore Refinery and Petrochemicals Limited confirmed a fire incident at its Coker Hydrotreater (CHT) unit on September 30, 2026, following the rupture of a high-pressure cold separator.
The incident occurred around noon at the Mangaluru facility. MRPL stated that the battery limits of the affected unit were isolated immediately, and emergency response teams engaged to control the blaze. The company clarified that the fire has been brought under control, though firefighting operations may continue for some time to ensure safe handling of the situation.
Incident details and safety status
The primary cause was identified as the rupture of the Cold Separator operating at high pressure within the CHT unit. This type of equipment is critical in refining processes for separating gas and liquid phases under pressure.
Regarding human impact, MRPL reported no major injuries. One individual sustained minor injuries and was shifted to a hospital. The company confirmed the injured person is out of danger and receiving necessary medical attention. The safety of personnel and the facility remains the highest priority, with the situation being closely monitored.
Operational context
As an Oil and Natural Gas Corporation (ONGC) subsidiary and a Schedule 'A' Government of India enterprise, MRPL operates a significant refining capacity. The CHT unit is integral to processing heavier fractions into lighter, more valuable products. While the immediate operational impact on total throughput is not quantified in the press release, the isolation of battery limits suggests a localized shutdown of that specific processing train.
The company issued a statement assuring the public that there is "absolutely no reason to panic" for individuals within or outside the MRPL premises. Further verified information regarding the extent of damage and timeline for resumption of operations will be shared as it becomes available.
