The Refinery


Nagarjuna Oil Corporation Limited (NOCL) is setting up a petroleum refinery at Cuddalore, Tamil Nadu, 180 km south of Chennai on the Bay of Bengal. This state-of-the-art project will refine 6 million metric tonnes of crude petroleum per year (MMTPA) in Phase-I, which is around 1,25,000 BPSD, and will primarily meet the growing energy needs of southern India. The project site is spread over an area of 2100 acres, including 300 acres of greenbelt.

It is the single largest private sector investment in Tamil Nadu and declared as anchor unit for the proposed Petroleum Chemical & Petrochemical Investment Region (PCPIR) in Tamil Nadu. The project includes infrastructure facilities that provide scope for further expansion of refining capacity by an additional 9 MMTPA in phase II.

Nagarjuna Group has partnered with the State Government of Tamil Nadu and Tata Petrodyne Ltd. to implement the refinery project. The company has also drawn up key alliances with technology and service providers.

The refinery is designed for producing feedstock of EURO III and EURO IV standards. The refinery can process some of the world’s sour crudes and is said to have Nelson Complexity Factor (NCF) of around 8.74. The Crudes that are processed in the refinery are Bonny Light and Arab Mix crude.

The Refinery’s primary units include Crude Distillation Unit (CDU) and Vacuum Distillation Unit (VDU) which is said to be the mother units, and secondary units include Catalytic Hydrodesulphurization Unit, Methyl Tertiary Butyl Ether Unit, Cold Box Unit, Fluid Catalytic Cracking Unit, Delayed Coker Unit, Diesel Hydrodesulphurization Unit and with supporting offsites and utilities systems consisting of product storage tankages, Captive Power Plant and marine facilities

The combination of relocated primary distillation units from Woerth Refinery Germany and new secondary processing units and offsite facilities offers an edge over others with competitive Capital Cost. Proximity to Karaikal port will help establish Single Point Mooring for crude import. The facility to handle up to 65,000 DWT tankers for exports / coastal movement makes the refinery, an ideal location for exports to SAARC and Southeast Asian countries.

The refinery is designed to cater to the domestic needs of the state. 70% of the total production is for the state marketing and the rest is for exporting.

We have roped in industry’s best technology providers and constructors including UOP, Axens, CB&I, Lummus Technology, Uhde Engineering, Technip, Aker Power Gas, Samsung Engineering Punj Lloyd and Petron Engineering Construction. Safety and well-being of Contractor personnel and NOCL Employee are accorded the highest priority.
