Apparatus for continuously introducing or removing gases into and/or

The apparatus for removing liquid films floating on liquids, in particular oil films floating on water, has a plurality of rotatably supported plates (3) which are driven for rotation around an axis (2) and which are immersed into the liquid level. The oil entrained by the surface of the plates (3) on emersion from the liquid level is stripped by means of strippers (4) and supplied to a collecting launder (5).

Apparatus for separating of liquid films floating on liquids

Apparatus for continuously recovering ethanol from fermentable sugar

The apparatus for continuously separating liquid phases of different density consists of a separating basin (1) within which are arranged partition walls (5) for being lifted and lowered and for being moved one in direction to the other or for being swivelled. Swivelling of the partition walls (5) is effected about an eccentrically arranged axis (7) such that during the swivelling movement the partition walls (5) are simultaneously lifted or lowered. The partition walls (5) can be driven by push rods (8) and thus be swivelled in the contrary sense. When swivelling the partition walls (5) in one direction, the liquid level is lifted in the chamber defined between the partition walls and is lowered in the adjacent chamber, noting that the portion having the lower specific gravity flows over the upper edge, assuming a lower level, of the one partition wall in one direction (11) and that the proportion having the higher specific gravity flows in direction of the arrow (12), i.e. in the opposite direction, below the bottom edge of the outer partition wall (5). The separated phases are collected at the front sides of the separating basin (1). Supply is effected by a supply means (10) approximately centrally of the separating basin (1).
