A method for recovering bio-oil from an emulsified bio-oil process stream, by adding a chemical additive system to the emulsified bio-oil process stream, wherein the chemical additive system comprises at least one surfactant and at least one hydrophobic particulate not based on silica. Bio-oil recovered from the method. A bio-oil recovery system, including a supply of emulsified bio-oil, a supply of chemical additive, wherein the chemical additive comprises at least one surfactant and at least one hydrophobic particulate not based on silica, a treatment unit for combining the chemical additive system with the emulsified bio-oil, and a centrifuge system for dewatering the treated emulsion and producing a concentrated bio-oil. |
