<p>The tank can be applied for separation of a water influent containing considerable amounts of oil and gas which in particular is suited for use in oil production for their removal before the water is returned into the sea. In tank (1) a rotational flow is created which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall (10) where they coalesce and rise to the surface of the liquid and are removed via outlet (3), whereas the heavier parts are forced down. The heavy parts sink to the lower part where they are removed as sludge. The water is discharged via an outlet (4), found in the lower part of the tank (1). 18 claims, 4 figures</p> |
