Carry-over to Lobe Compressor of Low poly Liquid Droplets in HDPE

Carry-over to Lobe Compressor of Low poly Liquid Droplets in HDPE

Carry-over to Lobe Compressor of Low poly Liquid Droplets in HDPE

(OP)
We have a lobe type compressor which circulates Nitrogen for conveying HDPE polymer powder to silos. This Nitrogen gets contaminated with Low boiling polymers in ppm level which condense inside the suction lines as well as blower. This leads to damage to the lobes as well as high amperage. The separator ahead of the compressor is a simple vertical gravity one and really does not help. Demister get choked frequently and normally not used in this service by Designer. Suction temperature is around 42 Deg C and Discharge Temp aroung 95 Deg C. Suction pr around 300 mm H2O and Disch Pr. around 0.6Kg/cm2. Flow is around 4000 NM3/hr. Suction K.O.pot and suction lines are insulated. Any Solutions??
Thanks
Mani
