Gujarat Refinery is situated at Jawahar Nagar, nearly 10 km North of Vadodara. Gujarat Refinery is the anchoring industry of Vadodara and is catering to the increasing energy demand due to the fast-paced development and economic prosperity of the vibrant state of Gujarat over the course of five decades.
Gujarat Refinery was set up as a 2 million tonne refinery. The first crude distillation unit, Atmospheric Unit-I (AU-I) of 1.0 MMTPA was commissioned in 1965. Today it is a 13.7 million tonne integrated refinery-cum-petrochemical complex.
Second crude distillation unit and Catalytic Reforming Unit was installed in 1966, the third 1.0 MMTPA crude distillation unit (AU-3) was commissioned in 1967 to process Ankleshwar & North Gujarat crudes. In December 1968, Udex plant was commissioned for production of benzene & toluene using feedstock available from CRU. By 1974-75, with in-house modifications, the capacity of the refinery was further increased to a level of 4.2 MMTPA. To process imported crude, the refinery was expanded during 1978-79 by adding another 3 MMTPA crude distillation unit (AU-4) along with downstream processing units like Vacuum Distillation, Visbreaker & Bitumen Blowing Unit. For recovery of high value products from the residue, the secondary processing facilities consisting of Fluidized Catalytic Cracking Unit (FCCU) was commissioned in 1982 and the crude processing capacity of the refinery was further increased to 9.5 MMTPA.
In 1993-94, Gujarat Refinery commissioned country’s first Hydrocracker Unit for conversion of heavier ends of crude oil to high value superior products. Country’s first Diesel Hydrodesulphurization Unit (DHDS) to reduce Sulphur content in diesel was commissioned in 1999. MTBE Unit was commissioned in 1999 to eliminate lead in MS.
By 1999, with commissioning of 5th crude distillation unit (AU–5), Gujarat Refinery further augmented its capacity to 13.7 MMTPA. In 2004, the world’s largest single train Linear Alkyl Benzene Plant with an annual capacity of 1,20,000 tonnes was set up marking IOCL’s big-ticket entry into Petrochemicals.
Under the resid upgradation project VGO-HDT (2.1 MMTPA), DHDT (2.2 MMTPA), HGU (72.5 TMTPA), ISOM (230 TMTPA), SRU (95 MT/hr), ARU (750 MT/hr), FCC & LPG Merox were done in 2010. Commissioning of ATF Merox (200 TMTPA), DCU (3.7 MMTPA) was done in 2011.
Further, the following units were added to meet the fuel specifications:
- To produce BS-IV/BS VI compliant fuel, revamp of Diesel Hydrodesulphurization (DHDS) / Hydrotreating (DHDT) unit and VGO Hydrotreating (VGO-HDT) were executed. Project was executed in two phases and completed in 2019.
- To meet Auto Fuel Vision & Policy of GoI a Fuel Quality Upgradation Project was taken up under which a New Diesel Hydrotreating Unit of 2.0 MMTPA, Prime G Unit of 0.7 MMTPA, Hydrogen Unit and Amine Regeneration Unit was commissioned in 2021.
Upcoming Projects: Gujarat Refinery expansion (J-18) from 13.7 to 18.0 MMTPA along with integration with LOBS and Petrochemicals is in progress and proposed to be commissioned in FY 2024-25.
