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
BASIC PROCESS IN REFINERY
MECHANICAL DEPARTMENT
Maintenance Various Components used:i. Centrifugal Pumps (SPLIT-CASING TYPE)ii. Screw Pumpsiii. Valvesiv. CompressorsMechanical Control Unit (MCU)
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
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
SCREW PUMP(+VE DISPLACEMENT)
• Used for High Viscous fluid
• High efficient as the flow increases
• mostly used for pumping lube oil
CAVITATION (NPSHA<NPSHR)
Cavitation Effects:
grinding of “marbles” Loss of capacity Pitting Vibration and mechanical damage such
as bearing failure Erratic power consumption
FAILURE MODES IN PUMP
Shaft Suction Valve Casing Operation CouplingGaskets Control Valve
VALVES Flow Control Valvesi. Gate ii. Globeiii. Balliv. Butterflyv. NRV
Safety Valvesi. PSVii. PRV
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

ROLE OF A MECHANICAL ENGINEER
• Mechanical Control Unit (MCU)
• Monitoring various parameters
• Communication with the control room staff
• Troubleshooting the problems
ENVIRONMENT CONSERVATION PRACTICES
• AIR POLLUTION
• WATER POLLUTION
• NOISE POLLUTION
• OHC
AIR POLLUTION CONTROL
5 Sulphur Recovery Units (99% recovery)
Tall stacks
Use of low S fuel oil, desulfurised fuel gas
Low Nox burners
WATER POLLUTION CONTROLZero Discharge RefineryEffluent Treatment PlantLarge ponds for aerobic storage of treated waterBenzene Vapour Recovery System at Naptha
NOISE POLLUTION CONTROL & OHC
EarplugsSilencers on
