Guwahati Refinery, the first public sector refinery of the country, was built with Romanian collaboration, was inaugurated by Late Pt. Jawaharlal Nehru, the first Prime Minister of India, on 1st January 1962.The pioneer among the public sector refineries, Guwahati Refinery symbolizes the Nation’s march towards indigenisation of the refining technology. With a capacity of 1.0 million metric tonnes per annum, Guwahati Refinery processes crude oil received from the Upper Assam Oil Fields and caters to the requirements of the petroleum products of the North Eastern Region.
Its major products are LPG, Motor Spirit (Petrol), Aviation Turbine Fuel (ATF), Kerosene, High Speed Diesel, Light Diesel Oil and Raw Petroleum Coke. Keeping pace with the changes in the industrial environment, Guwahati Refinery is making efforts to produce specialty products. It is the only refinery in India to produce green needle coke, a high value import substitute.
Entering into the era of ecologically friendly fuel, Guwahati Refinery has installed three new units: the ISOSIV, the Hydrotreater and the INDMAX. The ISOSIV unit produces Lead Free Petrol by the Molecular Sieve Technology, which separates Octane rich MS components from feed naphtha. The Hydrotreater Unit (HDT) enables the Refinery to produce High Speed Diesel of very low sulphur and cetane number conforming to BIS specifications. The HDT also produces ATF, Superior Kerosene Oil with high smoke point and low sulphur. The Indane Maximization (INDMAX) technology developed by R&D Centre of IndianOil installed at the Refinery is designed to achieve LPG yield as high as 44% through Fluidized Catalytic Cracking of residual feed stocks like Reduced Crude Oil, Coker Fuel Oil and Coker Gasolene. The INDMAX unit also enables Guwahati Refinery to upgrade all its residual products to high value distillate products and make it a zero residue Refinery.
The Refinery’s complies with the MINAS specifications with respect to quality and quantity of its effluents. A modernized effluent treatment plant with Dual Media Filters and Coke fine Settlers, full fledged pollution control laboratory and reuse of treated effluent in the Refinery ensures the adherence to applicable standards. Extensive tree plantation to the tune of forty one thousand saplings and development of Ecological Park, Environment Park and Sanjeevani udyan in and around the Refinery spearhead its efforts to the cause of ecological balance. The Refinery is ISO-14001 certified by Det Norske Veritas of the Netherlands.
Introduction of heat exchanger train optimization, yield and energy optimization of Crude Distillation Unit and Delayed Coker Units, installation and commissioning of high efficiency boilers have contributed to a great degree towards energy conservation. A new 12 MWSTG Vapour Blow Down Recovery System in DCU, Pressurized Cooling Tower system for old process unit facilitates reduction in energy consumption.
For quality management, The Refinery has integrated management system or IMS of the refinery including ISO-9001: 2000, OHSAS-18001 (Occupational Health Safety Associated System), Level-8 rating in ISRS (International Safety rating system). The refinery also has various system improvement initiatives like Total Productivity Maintenance (TPM) implemented in Delayed Coker Unit; Six Sigma implementation in certain areas to further ensure quality products and enhance productivity of the refinery.
