Seal oil leaks

Seal oil leaking into the feed from pumps covwed column packing with a thin hydrophobic film. This reduced wettability, which in turn cut efiidency in half. A detergent wash was only par-tialty effective for oil removal. Prt lem salved ly iqjecting a low concentration of nonvolatile surfactant during several days of operatian. 

Plant maintenance. Quality of air filtration system maintenance, frequency of compressor blade washing (deposition leads to higher surface blade rou mess, which in turn leads to faster rate of degradation), prevention of potential bearing seal oil leaks into air inlet stream, periodic water quality control in closed-loop evaporative cooling systems, etc., are all measures that can positively influence compressor fouling and their rate of fouling.
