Good day all,

I am working in a gas plant. our issue is with propane screw compressor package, we are suffering a lot from the damaging of the seal due to oil continamated with vapor water or some thing else. The colure of the oil changed to the milky oil and also the consumption of oil is too high>is any one could help us.

many thanks

Mustafa,
Maybe you need to check oil with oil analysis & find out what contamination is.
When you find out what it is check where contamination could come from, then go from there.

Excessive oil consumption could be damaged coalescers in oil separator, or loose. Replace/tighten.
Also liquid propane entering compressor could also wash oil out.
