Abstract
Abstract An oil separator of the demister-type wherein a conduit directs an oil containing gas into a tank, at least two demister packs in the tank, the first pack operating in a supersaturated condition and the last pack operating in an unsaturated condition, at least one baffle in the tank for reversing the gas flow before or after passing a demister pack to remove large and small oil droplets so as not to impose limitations on the capacity control of the compressor.

Claim 3
Dependent Claim
32 words
An oil separator according to claim 1, wherein said gas inlet, said passages and said baffles are arranged in such manner that said gas stream flows downwardly through said first demister pack.
Claim 4
Dependent Claim
29 words
An oil separator according to claim 1, comprising a third demister pack positioned on said first baffle such that the incoming gas stream in said conduit will impinge thereon.
Claim 5
Dependent Claim
37 words
An oil separator according to claim 1, wherein said means defining said first and second passages in said tank comprises a set of concentric tubes, said first and second demister packs being concentrically mounted in said tubes.
Claim 6
Dependent Claim
32 words
An oil separator according to claim 4, wherein said gas inlet, said passages and said baffles are arranged in such manner that said gas stream flows downwardly through said first demister pack.
Claim 7
Dependent Claim
35 words
An oil separator according to claim 5 wherein said means for collecting oil is located in the bottom part of said tank, and said gas outlet is located in the upper part of said tank.
Claim 8
Dependent Claim
34 words
An oil separator according to claim 1 comprising a line including a distributing device for introduction of cooling oil into the gas stream prior to entry into the inlet of said first demister pack.
Claim 9
Dependent Claim
24 words
An oil separator according to claim 7 wherein said distributing device includes a discharge outlet for the cooling oil into said first demister pack.
Claim 10
Dependent Claim
70 words
An oil separator according to claim 1 wherein said inlet is at the bottom of the tank and said gas stream flows upwardly in said conduit to said first baffle, then downwardly through the first demister pack, then upwardly through the second demister pack, said gas outlet being at the top of the tank, and said oil collecting means at the bottom of the tank in isolation from said inlet.
