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

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. BASIC PROCESS IN REFINERY

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. 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. 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. SCREW PUMP(+VE DISPLACEMENT)
• Used for High
Viscous fluid
• High efficient as
the flow increases
• mostly used for
pumping lube oil

12. CAVITATION
(NPSHA<NPSHR)

13. Cavitation Effects:
grinding of “marbles”
Loss of capacity
Pitting
Vibration and mechanical damage such
as bearing failure
Erratic power consumption

14. FAILURE MODES IN PUMP
Shaft
Suction Valve
Casing
Operation
Coupling
Gaskets
Control Valve

15. VALVES
 Flow Control Valves
i. Gate
ii. Globe
iii. Ball
iv. Butterfly
v. NRV
 Safety Valves
i. PSV
ii. PRV

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. GATE VALVE
GLOBE VALVE

18. Non Return Valves

19. SAFETY VALVES
PRESSURE SAFETY VALVE PRESSURE RELIEF VALVE

20. ROLE OF A MECHANICAL
ENGINEER
• Mechanical Control Unit (MCU)
• Monitoring various parameters
• Communication with the control room staff
• Troubleshooting the problems

21. ENVIRONMENT
CONSERVATION PRACTICES
• AIR POLLUTION
• WATER POLLUTION
• NOISE POLLUTION
• OHC

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. WATER POLLUTION CONTROL
Zero Discharge Refinery
Effluent Treatment Plant
Large ponds for aerobic storage
of treated water
Benzene Vapour Recovery
System at Naptha

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. SAFETY PRACTICES

26. LEARNINGS
Practical experience
Insight into the working of a PSUs
Useful Interactions with people
Environment and safety practices in a
industry
