TheGujarat Refinery is anoil refinery located at Koyali,Vadodara District in Gujarat, Western India. It is the third largest refinery owned byIndian Oil Corporation afterParadip andPanipat Refinery.[1] The refinery is currently[when?] under projected expansion to 18 milliontonnes per year.
Following the conclusion of theIndo-Soviet Treaty of Friendship and Cooperation in February 1961, a site for the establishment of a 2 milliontonnes per year oil refinery was selected on 17 April 1961.[2] Soviet and Indian engineers signed a contract in October 1961 for the preparation of the project. Prime MinisterJawaharlal Nehru laid the foundation stone of the refinery on 10 May 1963.[2]
The refinery was commissioned with Soviet assistance at a cost ofRs.26 crores began production in October 1965. The first crude distillation unit with a capacity of 1 million tonnes per year was commissioned for trial production on 11 October 1965 and achieved its rated capacity on 6 December 1965. Throughput reached 20% beyond its designed capacity in January 1966.[citation needed]
PresidentSarvepalli Radhakrishnan dedicated the refinery to the nation with the commissioning of second crude distillation unit andcatalytic reforming unit on 18 October 1966.[citation needed]
The third 1 million tonnes per year distillation unit was commissioned in September 1967 to processAnkleshwar andNorth Gujarat crudes. In December 1968, Udex plant was commissioned for production ofbenzene andtoluene using feedstock from CRU. By 1974–75 with in-house modifications, the capacity of the refinery increased by 40% to a level of 4.2 million tonnes per year. To process imported crude the refinery was expanded during 1978-79 by adding another 3 million tonnes per year crude distillation unit along with downstream processing units includingvacuum distillation,visbreaker andbitumen blowing units. By 1980-81 this unit started processingBombay High crude in addition to imported crudes. It was the first time that Indian engineers independently handled a project of that scale.[citation needed]
To recover products from the residue, secondary processing facilities consisting offluidized catalytic cracking unit of 1 million tonnes per year capacity along with a feed preparation unit of 1 million tonnes per year capacities, were commissioned in December 1982. The refinery set up pilot distillation facilities for the production ofn-Heptane and light aluminum rolling oils. To enable absorption of increased indigenous crudes the refinery's capacity was further increased to 9.5 million tonnes per year.[citation needed]
In 1993–1994, Gujarat commissioned the country's firsthydrocracker unit of 1.2 million tonnes per year along with feed preparation unit-2 and hydrogen generation unit-1 (GHC Complex), for conversion of heavier ends of crude oil to high value superior products.[citation needed]
India's first dieselhydrodesulfurisation unit to reducesulfur content in diesel was commissioned in June 1999. Amethyl tertiary butyl ether unit was commissioned in September 1999 to eliminate lead from motor fuels. The facility conceptualised and commissioned South Asia's largest centralisedeffluent treatment plant (ETP) by dismantling the four old ETPs in June 1999. By September 1999 with the commissioning of anatmospheric distillation unit, Gujarat Refinery further augmented its capacity to 13.7 million tonnes per year making it the largest public sector undertaking refinery of the country.[citation needed]
A project for production oflinear alkyl benzene fromkerosene streams was implemented in August 2004.[3] It is the largest grassroots single train Kerosene-to-LAB unit in the world, with an installed capacity of 1.2 million tonnes per year.[3] To meet future fuel quality requirements, motorgasoline (MS) quality improvement facilities were commissioned in 2006.[citation needed] The Residue Upgraation Project undertaken by the Gujarat Refinery was completed by 2011 which increased the high sulfur processing capacity of Gujarat refinery, improved the distillate yield as well produceBS III &IV quality of MS and high-speeddiesel (HSD).[4] The Residue Upgradation Project came in two parts namely, the south block which consisted of hydrogen generation unit (HGU)-III, solvent recovery unit (SRU)-III, diesel hydrotreatment (DHDT) andisomerization units and the north block which consisted of vacuum gasoilhydrotreating (VGO)-HDT anddelayed coker units. To support the new units a newco-generation plant (CGP) andheat recovery steam generator (HRSG) were also commissioned.
The refinery's facilities include five atmospheric crude distillation units. The major secondary units includecatalytic reforming unit (CRU),fluidized catalytic cracking unit (FCCU) and the firsthydrocracking unit of the country. Through a pipeline toAhmedabad and a pipeline connecting to the Barauni-Kanpur pipeline (BKPL) and also by rail and truck, the refinery primarily serves the demand for petroleum products in western and northern India.[citation needed]
When commissioned, the refinery had an installed capacity of 2 milliontonnes per year and was designed to process crude from Ankleshwar, Kalol and Nawagam oilfields ofONGC in Gujarat. The refinery was modified to handle imported and Bombay High crude. The refinery also produces a wide range of specialty products such asbenzene,toluene,mineral turpentine oil, food gradehexane,solvents andkerosene.[citation needed]
The Gujarat Refinery is the first refinery in India to have completed the diesel hydrodesulfurization project in June 1999, when the refinery started production of HSD with low sulfur content of 0.25%wt (max).[citation needed]
