Hindustan Petroleum Corporation has informed that an unfortunate fire incident occurred on 20 April 2026 in the Crude Distillation Unit (CDU) section of the refinery of HPCL Rajasthan Refinery Limited (HRRL), a Joint Venture company of Hindustan Petroleum Corporation. Prima facie it appears that leakage of hydrocarbons through one of the valves/flanges in the heat exchanger circuit caused the fire. The fire was localized in the heat exchangers stack. Crude Distillation Unit (CDU), Vacuum Distillation Unit (VDU) and all other Units of the CDU section were quickly isolated. All are structurally safe and unaffected. No other section of the refinery has suffered any impact. The fire was promptly brought under control by the emergency response team of HRRL. There is no loss of life or injury to any personnel. As a precautionary measure, the scheduled dedication of the refinery by the Hon’ble Prime Minister on 21 April 2026 has been postponed. A revised date will be announced in due course. An investigation has been initiated to ascertain the cause of the incident and to undertake necessary remedial measures. The financial and operational impact, if any, is being assessed and Prima facie is not expected to be material.
