  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
