IOCL Vocational Training (Mechanical Department) Powerpoint Presentation

  1. 1. VOCATIONAL TRAINING PRESENTATION By: VISHAL SRIVASTAVA Mechanical Engineering VII Semester SKIT, Jaipur IOCL, PANIPAT
  2. 2. INDIAN OIL-ENERGY OF INDIA Key player in Indian Energy Sector PSU Maharatna, meeting 47% of national petroleum demands Capacity: 65.7 MMTPA 63% market share in Aviation Fuel Leading Indian Corporate, ranked at 83rd position in latest Fortune ‘GLOBAL 500’ listing
  3. 3. Operations Refining Pipeline Transportation Petroleum Products and Petro-chemicals Exploration of Crude Oil and Gas
  4. 4. ATF SULPHUR INDANE Gas Xtra Premium Petrol Petrochemi cals HSD LPGSERVO Lubricants BITUMEN HEAVY PETROLEUM STOCK Products from Refinery
  5. 5. Barauni Haldia Mathura Digboi Guwahati Gujarat Panipat
  6. 6. PANIPAT REFINERY 7th refinery of Indian oil . Largest integrated Refinery and Petrochemicals Hub in India and 3rd in South-East Asia Present Capacity: 15 MMTPA Designed for high sulphur crude 0 Discharge Refinery
  7. 7. BASIC PROCESS IN REFINERY
  8. 8. MECHANICAL DEPARTMENT Maintenance Various Components used: i. Centrifugal Pumps (SPLIT-CASING TYPE) ii. Screw Pumps iii. Valves iv. Compressors Mechanical Control Unit (MCU)
  9. 9. REQUIREMENT OF PUMPS IN REFINERY • For circulation of cooling water • For pumping the fluid (crude oil,diesel etc.) in reactors, etc. with high pressure. • In liquid storage tanks
  10. 10. SPLIT CASING PUMP to pump clean water or low viscosity clean liquids at moderate heads  Less noise and vibration risk of water hammer is lower Unique design for high temperature application
  11. 11. SCREW PUMP(+VE DISPLACEMENT) • Used for High Viscous fluid • High efficient as the flow increases • mostly used for pumping lube oil
  12. 12. CAVITATION (NPSHA<NPSHR)
  13. 13. Cavitation Effects: grinding of “marbles” Loss of capacity Pitting Vibration and mechanical damage such as bearing failure Erratic power consumption
  14. 14. FAILURE MODES IN PUMP Shaft Suction Valve Casing Operation Coupling Gaskets Control Valve
  15. 15. VALVES  Flow Control Valves i. Gate ii. Globe iii. Ball iv. Butterfly v. NRV  Safety Valves i. PSV ii. PRV
  16. 16. REQUIRMENT OF VALVES • Its function can be stopping or starting the flow, controlling flow rate, diverting flow • preventing back flow, controlling pressure, or relieving pressure. • control of fluid flow or pressure is required • Very important for safety
  17. 17. GATE VALVE GLOBE VALVE
  18. 18. Non Return Valves
  19. 19. SAFETY VALVES PRESSURE SAFETY VALVE PRESSURE RELIEF VALVE
  20. 20. ROLE OF A MECHANICAL ENGINEER • Mechanical Control Unit (MCU) • Monitoring various parameters • Communication with the control room staff • Troubleshooting the problems
  21. 21. ENVIRONMENT CONSERVATION PRACTICES • AIR POLLUTION • WATER POLLUTION • NOISE POLLUTION • OHC
  22. 22. AIR POLLUTION CONTROL 5 Sulphur Recovery Units (99% recovery) Tall stacks Use of low S fuel oil, desulfurised fuel gas Low Nox burners
  23. 23. WATER POLLUTION CONTROL Zero Discharge Refinery Effluent Treatment Plant Large ponds for aerobic storage of treated water Benzene Vapour Recovery System at Naptha
  24. 24. NOISE POLLUTION CONTROL & OHC Earplugs Silencers on compressors Acoustic equipments Regular monitoring of work environment under OHC Development of Green Corridor and Ecological Park
  25. 25. SAFETY PRACTICES
  26. 26. LEARNINGS Practical experience Insight into the working of a PSUs Useful Interactions with people Environment and safety practices in a industry
