DEVICE FOR OIL AND WATER SEPARATION, AND SYSTEMS FOR OIL SPILLS GATHERING INCLUDING SUCH DEVICE Russian patent published in 2016 - IPC B01D17/22 E02B15/10 C02F1/40 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the device for oil and water separation. The device contains a chamber (2) for oil accumulation, enclosed by the wall (1), wherein at least part of the wall (1) surface is coated by the porous, oleophilic, and hydrophobic layer (3), that permits water and oil penetration through it. The device also contains a fixing layer (4) coating the surface of the porous, oleophilic, and hydrophobic layer (3), to limit dispersion of the porous, oleophilic, and hydrophobic layer, wherein the fixing layer (4) ensures water and oil penetration through it, wherein the diameter of pores of the said porous, oleophilic, and hydrophobic layer (3) is 300-850 mcm, and porosity is 10-40%. The oleophilic and hydrophobic layer (3) is cluster of silicone sand with applied coating, wherein sphericity of the silicone sand with the applied coating is at least 0.7, particles diameter is 300-850 micron, and density of the cluster is 1.4-1.65 g/cm³.

EFFECT: invention increases efficiency of the oil spills gathering, and is suitable for the oil spills gathering from large sea areas.
