Hi,

I'm trying to find literature to understand screw coalescing oil separators, but there is very little and scattered. I know it is part of package compressor manufacturer.
I wonder,
1). What residence time & oil drop size (or oil terminal velocity) are used in gravity section?
Stoecker recomends vapor velocities about 0,76 m/s. With residence time of 3 sg, there is a gravity section length of 2,28m which makes sense.
2). For oil reserve, some authors used 1.20 x compressor oil load recommended by the manufacturer and other from 3 to 5 min. by oil flow.

What do you think?

Thanks.
