A method for producing an additive for reclaiming oil from a fluid product stream and a treated silica with controlled hydrophobicity are disclosed. The method includes the steps of providing silica or silicate with a particle size of between 3.0 &#x3bc;m to 20 &#x3bc;m, the silica or silicates having an agglomerate size of between 10 &#x3bc;m to 100 &#x3bc;m and being chosen to achieve the desired particle-size range and with a controlled level of hydrophobicity; treating the silica or silicate with a silicone or silane to make it hydrophobic; and controlling the hydrophobicity of the silica or silicate by varying the temperature and treatment time of the silica or silicate, amount of a treating material used to treat the silica or silicate, and the molecular weight of the treating material. The additive improves oil extraction and concentration from a fluid product stream.

Demulsification compound for oil separation from waste streams

A method for producing an additive for reclaiming oil from a fluid product stream and a treated silica with controlled hydrophobicity for use in the method are disclosed. The method includes the steps of providing silica or silicate with a particle size of between 3.0 &#x3bc;m to 20 &#x3bc;m, the silica or silicates having an agglomerate size of between 10 &#x3bc;m to 100 &#x3bc;m and being chosen to achieve the desired particle-size range and with a controlled level of hydrophobicity; treating the silica or silicate with a silicone or silane to make it hydrophobic; and controlling the hydrophobicity of the silica or silicate by varying the temperature and treatment time of the silica or silicate, amount of a treating material used to treat the silica or silicate, and the molecular weight of the treating material. The additive and related method improves oil extraction and concentration from a fluid product stream.
