Device for skimming a surface fluid

A device for skimming petrochemical or chemical fluid storage tanks working by gravitation, the petrochemical or chemical fluid having a density d2 and being covered by a surface fluid with a density d1 lower than d2, the device comprising:

• a buoyancy apparatus floating at an interface between the fluid with density d1 and the fluid with density d2;
• a collector for collecting surface fluid to be skimmed including an opening emerging above the interface between the fluid with density d1 and the fluid with density d2, the collector being connected to the buoyancy apparatus, and a connector submerged in the fluid with density d2;
• and
• a discharger for discharging the collected surface fluid, the discharger being connected to the connector of the collector and extending vertically in the fluid with density d2 toward the bottom of the tank,
• the discharger comprising at least two flexible pipes connected symmetrically to the connector.
