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

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
