Haldia Refinery, one of the eight operating refineries of Indian Oil, was commissioned in January 1975. It is situated 136 km downstream of Kolkata in the district of Purba Medinipur, West Bengal, near the confluence of river Hoogly and Haldi.
From an original crude oil processing capacity of 2.5 MMTPA, the refinery is now operating at a capacity of 7.5 MMTPA at present. Capacity of the refinery was increased to 2.75 MMTPA through de-bottlenecking in 1989-90, and to 3.75 MMTPA in 1997 with the installation/commissioning of the second Crude Distillation Unit of 1.0 MMTPA capacity. Petroleum products from this refinery are supplied mainly to eastern India through two product pipelines as well as through barges, tank wagons and tank trucks. Products like MS, HSD and Bitumen are exported from this refinery.
Haldia Refinery is currently the only coastal refinery of the corporation and the lone lube flagship, apart from being the sole producer of Jute Batching Oil. Diesel Hydro Desulphurisation (DHDS) Unit was commissioned in 1999, for production of low Sulphur content (0.25% wt) High Speed Diesel (HSD). With augmentation of this unit, the refinery is producing BS-II and Euro-III equivalent HSD (part quantity) at present. Resid Fluidised Catalytic Cracking Unit (RFCCU) was commissioned in 2001 in order to increase the distillate yield of the refinery as well as to meet the growing demand of LPG, MS and HSD. Refinery also produces eco friendly Bitumen emulsion and Microcrystalline Wax. A Catalytic Dewaxing Unit (CIDWU) was installed and commissioned in the year 2003 for production of high quality Lube Oil Base Stocks (LOBS), meeting the API Gr-II standard of LOBS.
In order to meet the Euro-III fuel quality standards, the MS Quality Improvement Project has been commissioned in 2005 for production of Euro-III equivalent MS. The refinery expansion to 7.5 MMTPA as well as a Hydrocracker project has been approved, commissioning of which shall enable Haldia Refinery to supply Euro-IV and Euro – III HSD to the eastern region of India.
