The opaque gas mixture you see is what has been drained out sitting on the bottom of the separator and is actually an indication that it is doing its job correctly. Now that it is drained I would run it as is and check it again to see how bad the problem is as it could have just been an accumulation over a long time.
It is also best practice to put a new separator on it as there is no telling how old the current one is. put the date on the new one with a marker.
