What Happened ?
HPCL informed stock exchanges that the restoration work at the Crude Distillation Unit (CDU) of HPCL Rajasthan Refinery Limited (HRRL), its joint venture refinery, has been successfully completed. The restoration followed a localized fire incident that occurred in the CDU heat exchanger stack on April 20, 2026.
The CDU has been restarted and product streams from the CDU and Vacuum Distillation Unit (VDU) are now being produced and routed for downstream processing. The refinery has already begun production of several key petroleum products and is progressing toward normal operations.
Key Details
HRRL Refinery Restart and Production Ramp-Up:
- Restoration work at the CDU has been completed successfully.
- The CDU has restarted operations after the April 2026 fire-related shutdown.
- Product streams from the CDU and VDU are being routed to downstream processing units.
- Production has commenced for BS-VI High Speed Diesel (HSD), LPG, Petcoke and Naphtha.
- Commercial sales of LPG and Petcoke have already started.
- Dispatches of BS-VI HSD are expected to commence by the end of the current week.
- Production and dispatches of BS-VI Motor Spirit (Petrol) are expected to begin during the following week.
- HRRL is progressively ramping up refinery operations toward optimal capacity utilization.
Note:
- The successful restart marks a significant operational recovery milestone for HRRL and restores the refinery’s ability to process crude and supply petroleum products after the disruption caused by the April fire incident.
Risk Analysis
Summary:
- Although refinery operations have resumed, the facility remains in the ramp-up phase. Achieving optimal utilization levels and stable production rates will depend on operational execution and continued reliability across refinery units.
Key Risks:
- Refinery operations are still transitioning toward full capacity utilization.
- Production ramp-up may take time before reaching optimal throughput levels.
- Operational stability across interconnected downstream units remains critical.
- Any unforeseen technical disruptions could affect planned production schedules.
Worst Case Scenario:
- If operational ramp-up encounters technical or process-related challenges, the refinery may take longer than expected to reach optimal production levels and planned product dispatch schedules.
Risk Level: Medium
