Questions and Answers
How does the system ensure the motors are intrinsically safe?
The motors are supplied with filtered, fresh air that is passed through them by the purge air blowers.
What role do the auxiliary lube oil pumps play in the lubrication system?
They maintain lubrication during start-up and stand-by service.
Why is cooling water routed to the cylinder rods of the motor drivers?
Cooling water is routed to manage the temperature and ensure efficient operation of the motor drivers.

Study Notes
Compressors Motor Purge System
- Fresh air enters the system through a weatherproof 25’ air inlet stack.
- Filtering of air occurs via F-121 (Purge Air Filter) before reaching the compressors.
- C-121A/B (Purge Air Blowers) ensure filtered air flows through C-120A/B (Charge Gas Compressors) and C-360A/B (Booster/Recycle Compressors) motors.
- The purge system is critical for intrinsic safety to meet Class I, Division I electrical classification standards.
- A loss of fresh purge air paired with flammable gas can lead to potential explosions or fires, with motors being ignition sources.
Crankcase Oil and Cooling Water System
- Crankcase oil is supplied from D-140 (Crankcase Oil Storage Drum) to C-120A/B (Charge Gas Compressors) Frame Oil Reservoirs as make-up oil.
- Main lube oil pumps P-122A/B-1 circulate oil to E-122A/B-1 and E-122A/B-2 (Lube Oil Coolers), where it is cooled by water.
- Auxiliary lube oil pumps P-122A/B-2 provide service during start-up and standby.
- Oil is filtered through F-122A/B-1 or F-122A/B-2 before reaching CM-120A/B (Motor Drives) bearings.
- Crankcase oil returns to the reservoirs after lubrication.
- Cooling water is distributed to both cylinders of CM-120A/B and through FI-123A/B-1 or FI-123A/B-2 cooling filters for piston and tail rods.
Rod and Cylinder Lubricator System
- P-121A/B (Lubricator Pumps) deliver lubricating oil to the rod packings and cylinders of C-120A/B.
- A hand pump is available for lubrication during pump maintenance or repairs, isolated from the system when not in use.
- A vent is incorporated in P-121 to allow for inventory checks and air bleeding from the system.
- Oil leaks are critical to prevent; inadequate lubrication can damage packing and compromise system containment.
