Hi Everyone,
My name is Cuong and now i am working on a FPSO. Our facility has Dewpoint control system for process gas.
Frick Crew compressor PDSH 163L is used now:
- Lube oil: Frick #12b (regular check and analysis)
- Compressor maintenance is carried out regularly and follow maker schedule.
- Refrigerant: Propane (yearly charging and weekly leaktest)
- Operating parameters:+
suction pressure 4 barg
+
Suction temp 1-2oC
+
discharge pressure 11-11.5 barg (Normal operating)
+
Discharge temp 55oC
Recently, compressor discharge pressure was dropped to 9.5 barg and approached to low alarm limit (9 barg). We already charged 02 bottles propane for this system but discharge pressure just increase a little bit to 10.5 barg.
Could you guys explain or help me to find problems?
Best regards,
Cuong LM
