INDIAN OIL CORPORATION LIMITED Refinery, (Gujarat)

Unit Profile

IndianOil Gujarat Refinery was dedicated to the Nation in 1966 changing the landscape of a town, a state and the country. Today, Gujarat Refinery is the Flagship Refinery of IndianOil, India’s largest commercial enterprise with a sales turnover of Rs. 4,50,756 crore in 2014-15 and highest Indian corporate in Fortune’s prestigious ‘Global 500’ listing of the world’s largest corporates.

The expansion in Gujarat Refinery has taken place in phases over the years from 2 Million Metric Tonnes per year to the present capacity of 13.7 MMT per year and is gearing up for further expansion. Gujarat Refinery and the city of Vadodara have been witness to each other’s phenomenal growth.

Gujarat Refinery is the 3rd Refinery of IndianOil and is situated at Jawahar Nagar, nearly 10 km North of Vadodara. The Refinery is spread over an area of 1950 acres including Asoj and Dumad terminal. The first crude distillation unit, Atmospheric Unit-I (AU-I) of 1.0 MMTPA was commissioned in October 1965. Gujarat Refinery is designed to processes indigenous as well as imported crude oil.

268 Today, Gujarat Refinery is the Mother 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. The Refinery has been playing a catalytic role in encouraging over 200 small and big industries over the course of five decades.

One of the most complex refineries in India, Gujarat Refinery has about 40 operating units. Over the course of five decades, the Refinery has kept up with the latest technological advancements and boasts of every modern unit and technology that is available in the IndianOil, Oil & Gas industry today.

Gujarat Refinery is also privileged with the distinction of setting up the country’s first Fluidized Catalytic Unit (FCCU) in 1982 and the first Hydrocracker plant in 1993. The country’s first Diesel Hydro Desulphurization Unit (DHDS) to reduce sulphur content was set up in 1999 to meet BS-II quality of HSD. MS Quality Improvement Project comprising of Continuous Unit (CCRU) and revamp of DHDS were carried out in the years 2006 and 2007 respectively to meet BS-III MS and HSD quality respectively. Further, the Resid Upgradation Project (RUP) and MS/HSD quality improvement project were commissioned in 2010-11. Gujarat Refinery is now gearing up for 100% supply of BS-IV fuels and capacity expansion to 18 MMT per year.

In 2004, the world’s largest single train Linear Alkyl Benzene (LAB) Plant was set up in the refinery marking IndianOil’s big-ticket entry into the Petrochemicals field. Today, the refinery holds the 2nd largest market share of LAB in India and exports to over 20 countries.

State-of-art Central Effluent Treatment Plant (CETP) has been installed to meet the revised MINAS specifications. Total treated effluent recycling in the cooling tower is already been in place as a part of IndianOil’s fresh water conservation policy.

The green belts, spread across an area of 139 acres in and around the refinery speak volumes about its commitment towards environment. With more than two Lacs strong tree population Gujarat Refinery’s three green belts act as lungs for the refinery. A beautiful Eco Park has been developed inside the green belt area surrounded by the pond which is a haven for various bird species.

Gujarat Refinery has full-fledged Effluent Treatment Plants consisting of physical, chemical, biological & tertiary treatment facilities. Various measures have been adopted for control of gaseous emissions. Water conservation is another important area being vigorously taken up in refineries through its quality control, re-use of treated water and maximum use in cooling systems.

Gujarat Refinery has strong safety management system and infrastructure with focus on behavioral safety.

269 Being an integral part of the city of Vadodara, Gujarat Refinery is committed to improving the quality of life in communities in and around the refinery and the city. Under CSR initiatives Gujarat Refinery has taken up projects for ensuring Clean Drinking Water, Health and Medical Care and Education in the nearby villages and communities.

Gujarat Refinery is also accredited with ISO-9001: 2008, ISO-14001: 2004 OHSAS 18001: 2007.

The average steam and power load of the refinery are 505 MT/hr Steam (HP+MP) and 110 MW Power.

By optimising the power plant operations in TPS Boilers 1,2 and 3 are idled. And in the process of energy conservation, fuel loss reduction STG 1, 2,3 are also idle.

270 Energy Conservation Measures

Gujarat refinery has implemented various energy conservation measures over the years and has successfully reduced its energy intensity index (EII) from 151 in 2010-11 to 106 in 2014-15. 22 Nos. of ENCON measures were taken up in 2014-15 which has resulted in saving of 39556 SRFT on an annual basis.
