Free Water Knock Out FWKO A Free Water Knock Out which is abbreviated as FWKO is also known as a vertical or horizontal three 3 phase separator used mainly to remove any free water being held in the vessel. Free water that remains in the vessel can cause problems such as formation of hydrates, corrosion or tight emulsions which are difficult to break. A free water knock out (fwko), is commonly called a three 3 phase separator because it can separate gas, oil and any free water. After separation of remaining liquids, the liquids are then passed into a separate vessel called a treater. |
