Performance of a rotating drum skimmer in oil spill recovery
free download
Oil spill recovery by means of a rotating drum skimmer was investigated experimentally for a wide range of design and operating conditions. The effect of drum diameter, drum length, rotating speed, oil film thickness, oil properties, and drum centre height above the oil/water

To help ensure that the skimmed oil does not contain excessive water, many API separators also include an oil roll skimmer. This For this reason, an oil skimmer pipe is almost always used as a backup oil removal de- vice. Oil

The main advantage of this type of skimmer is that, the oil that is collected can be recycled. Suction skimmers do not do very well in rough or choppy water because the wave action will force more water than oil into the skimmer.
