3. INTRODUCTION Indian Oil Corporation  (IndianOil) is India’s Largest Commercial Enterprise. Standing true to its corporate vision of being ‘The Energy of India’, IndianOil has been successfully meeting the energy demands of India for more than five decades.  It is the leading Indian Corporate in Fortune’s prestigious ‘Global 500’ listing of world’s largest corporates at 161st position for the year 2016. The IndianOil Group owns and operates 11 of India's 23 refineries with a combined refining capacity of 80.7 MMTPA. The refineries of IOCL in Assam are: Digboi refinery Guwahati refinery Bongaigaon refinery

4. GUWAHATI REFINERY Guwahati Refinery  was set up at  Noonmati  in  Guwahati  on January 1, 1962. 1 st Public Sector refinery of India. The refinery was inaugurated by Late  Pandit Jawahar Lal Nehru , the first Prime Minister of independent India. The refinery was built with  Romanian  Collaboration and has a capacity of 1.0 million metric tonnes per annum. Guwahati Refinery also ventured into  ecologically friendly fuel and subsequently installed 3 new units: the  ISOSIV , the  Hydrotreater  and the  INDMAX .

6. MECHANICAL EQUIPMENTS PUMP COMPRESSOR VALVES BEARINGS AIR PREHEATER HEAT EXCHANGER

7. PUMP CENTRIFUGAL PUMP Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. RECIPROCATING PUMP A  reciprocating pump  is a class of positive-displacement pumps. It is often used where a relatively small quantity of liquid is to be handled and where delivery pressure is quite large.

8. AIR COMPRESSOR Mechanical device that increases the pressure of a gas by reducing its volume. In refinery compressor are used to pump out product like LPG, steam and other gases. HEAT EXCHANGER A  heat exchanger  is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact.

9. VALVES A  valve  is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Ball Valve Butterfly Valve Globe Valve Gate Valve Check Valve

10. AIR PREHEATER Air preheater  are heat exchanger to preheat or  air heating of the combustion  air  by means of flue gas, steam, water or thermal oil.  Air preheaters  are used when exhaust temperatures of combustion systems are particularly high. BEARINGS A  bearing  is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.  Bearings requires maintenance and lubrication.

11. MAINTENANCE Maintenance is a sum of activities which keep the machines in condition that enable uninterrupted implementations of plans involving its use and while in doing so optimize the maintenance cost. Different maintenance practice has been practiced by different maintenance personnel. However all these maintenance practices can be classified into two main types: Breakdown Maintenance Practice Preventive Maintenance Practice

12. DEMINERALIZED WATER PLANT Demineralization  is the process of removing mineral salts from water by using the ion exchange process. Demineralised water is water completely free (or almost) of dissolved minerals as a result of one of the following processes : Distillation Deionization Membrane filtration (reverse osmosis or nanofiltration)  Electrodialysis

13. THERMAL POWER STATION 28MW thermal power station of IOCL, Guwahati for generation of electricity and process steam for the units. Three steam turbines (1×12 MW, 2×8 MW). Operating on Rankine cycle. Water is heated into steam and spins a steam turbine which either drives an electrical generator. After it passes through the turbine the steam is condensed in a condenser and recycled to where it was heated.

14. CRUDE DISTILLATION UNIT (CDU) Primary unit of the Refinery : The Crude Distillation Unit (CDU), desalted crude from the desalter is heated up through a series of heat exchangers and is fed into a pre fractionator column. The outputs from CDU are gasoline, Kero -I, Kero -II and Straight Run Gas Oil. Reduced Coke Oil (RCO) which is the bottom product from the main fractionating column, forms the main raw material for Coking unit and Indmax . 

15. DELAYED COKING UNIT Main secondary unit : The Delayed Coking Unit (DCU), the Refinery produces middle distillates from heavy ends. Main feedstock to DCU is RCO, which is heated to high temperatures of about 500oC in a furnace. Due to high temperatures, RCO is thermally cracked and yields various hydrocarbon fractions like: LPG, Coker gasoline, Coker kerosene, Coker gas oil, Coker fuel oil, Residual fuel oil and Coke.

16. INDMAX UNIT The Refinery has progressively improved its operations in terms of energy efficient state-of-the-art technologies and production of clean fuels meeting emerging quality requirements. The Indane Maximisation (INDMAX) technology is an in-house technology developed by R&D Centre of IndianOil. The INDMAX technology was first commissioned at Guwahati Refinery. The technology is being globally licensed by M/s Lummus Technology Inc., USA (a CB&I Company). INDMAX unit is designed by Lummus employing proprietary efficient hardware components with basic process design from IndianOil . Advantages Higher Octane of Gasoline (RON >96) Lower Catalyst Consumption.

17. OIL MOVEMENT AND STORAGE DIVISION Functions of OM &S Receipt, storage, accounting, preparation and supply of crude oil to DCU. Receipt and storage of intermediate and finished products from production units. Blending of products and chemical dozing. Dispatch of finished products. Measurement of petroleum products – gauging and sampling. Filling and dispatch of LPG in bulk dispatches in bullets mounted on trucks.

18. PLANNING SECTION Budgetary Control Optimum Utilization Planning & Execution of different types of activities

19. ENVIRONMENT PROTECTION The Refinery’s concerns for environment protection is further demonstrated by extensive tree plantation and development of Ecological Park and Sanjeevani Udayan in and around the Refinery further spearhead its efforts to the cause of ecological balance. Planting and preserving bio-diversified species are continual efforts in preserving bountiful nature. Periodic campaigns are also carried out in the neighbourhood to bring home the importance of clean environment.  Latest Energy Conservation measures also resulted in water conservation.  “ Prakriti Ke Saath – Pragati Ki O’r ” explains the Refinery’s commitment to environment. The Modernized Effluent Treatment Plant commissioned in March’07, the continuous environment monitoring system.

20. LEARNING’S

21. CONCLUSION In line with Indian Oil’s responsibility towards the society, Guwahati Refinery has contributed towards developing the community, which exists around it. The CSR agenda of the Refinery focuses on three broad areas of education, health care and providing water supply . Initiatives taken under these heads are participative in nature with community participation in a partnership model for ensuring sustainable development of the community.
