Free Water Knock Outs (Oil Skimmer Vessel)

Typically horizontally oriented, a Free-Water-Knock-Out is a three-phase vessel designed to handle a large amount of water with a small amount of oil.  By removing large volumes of water with an FWKO, downstream equipment can be sized for a smaller water to oil ratio, thereby reducing heat and chemical requirements. Free-Water-Knock-Outs are normally placed near the beginning of a facility so that the downstream equipment does not have to be sized based on the large water volume.
