2.2. Low Pressure Isolation and Over-Pressurization If the low-pressure side of the PX G energy recovery device is isolated before the high-pressure side is depressurized, the PX G unit or the low-pressure piping may be damaged by over-pressurization. High-pressure CO2 will seep through the PX device’s hydrodynamic bearing to low-pressure regions in the PX G unit.
PRODUCT DESCRIPTION ELECTRICAL 4.1. Wiring Diagram The appliance should be installed per national wiring regulations. Page 7 of 13 ERI Document 80809-01...
INSTALLATION 5.1. Installation Each unit has four connections labeled HP IN, HP OUT, LP IN, and LP OUT. HP IN is the high-pressure CO2 from gas cooler inlet. HP OUT is the high-pressure CO2 Outlet LP IN is the low-pressure CO2 flash gas inlet. LP OUT is the low-pressure CO2 to refrigeration cases The PX G unit must be supported by its bottom housing and not by the pipe fittings.
The following procedures are general guidelines for the startup and shutdown of PX G unit systems. Procedure details will vary by plant design. Contact Energy Recovery if your process design significantly differs from that shown in Figure 1. Always ensure that the operating limits listed in Section 1.3 are followed.
Check Nuts/Bolts that attach the motor/housing Check Pressures/Temperatures 7.3. Spare Parts Available spare parts and accessories are available at Energy Recovery Inc. Contact Energy Recovery for any spare parts and work to be completed. 7.4. Leaks from Pressure Exchanger If a leak is visible from the Pressure Exchanger, the PX should automatically shut off Ensure the PX is shut down and shut in (bypassed) If CO2 is detected near the motor to housing mating area, it is likely the shaft seal has been damaged.
