Apparatus for the selective and continuous recovery of hydrocarbons forming a layer on the surface of an aqueous medium.

摘要

Device allowing the selective and continuous recovery of hydrocarbons present in the form of a sheet or nappe at the surface of an aqueous medium. It is essentially constituted by a roller covered with a hydrophobic and oleophilic material 5 partially surrounded by a mobile recipient 6 provided with evacuation means of the aqueous medium 52. This device is particularly well adapted to the deoiling of a decanting basin.
